The topic of waste disposal is very relevant today, and I want to draw attention to glass containers. Its share in city landfills, as well as in spontaneous landfills in forests, is very significant. This is due to the basic lack of information among the population about the benefits of adding broken glass to concrete solutions. It has been scientifically proven that the addition of broken glass significantly increases the strength of concrete.
So, it took us at least a thousand bottles to concrete the roof of the garage. They picked them up right on the street. If summer residents knew about the benefits of broken glass, the percentage of bottles in trash bins would be significantly reduced.
Adding broken glass creates reliable waterproofing and extends the service life of concrete. But you need to take precautions when breaking bottles. You need to wear safety glasses and beat in a container, for example, in a bucket. It is most convenient to crush glass between two bricks.
Please pay attention to this issue. You just need to inform the population, talk to them, explain the inadmissibility of throwing away, for example, batteries with food waste, etc. It's all about competent organization.
Tatiana Lanskaya
Northern summer resident:I have never heard of a roof being concreted this way, but everything related to the foundation, steps, garden homemade tiles etc. quite fair. Here is some collected life experience so far:
1. "From personal experience I know that any glass container and even broken glass can be used in the manufacture of floors on the ground. To do this, dig a special hole no more than 20 centimeters deep. Then it is covered with any glass. In this case, all the broken glass acts as filler. The floor itself is laid on top of the glass. Do not forget that in this case, glass containers can become the most reliable protection against various living creatures, for example, from moles. Empty bottles can replace even the most high-quality insulation. Earlier during construction country houses used only empty bottles. They were laid in continuous layers under the floor. They were also used when laying out a concrete blind area."
2. "The only, somewhat acceptable and in a safe way the use of broken glass in construction, I would say its use in the drainage layer under the foundations. That is, you can pour pre-crushed glass along with sand and crushed stone into a cushion for pouring the foundation. Why is it undesirable to use it as a filler in concrete solutions (instead of crushed stone)? Because glass, unlike crushed stone, is smooth, therefore, its adhesion to the cement-sand mixture will be insufficient. Thus, the resulting concrete will be weaker than that made from pure crushed stone."
3. “You can recycle cullet, using it for laying a foundation, using binding materials, in the form of a solution with the addition of 1 part of M400 cement, 2 portions of sand and one part of cullet. The bottles must be carefully broken so that their fragments, such as the neck, do not remain intact ", which may not be filled with solution, so reliable foundation strength will not be achieved. And from whole bottles, having foamed each neck, you can build a fence. So, there is no need to throw away such an economical and environmentally friendly building material."
4. “We also found a lot of glass containers at our dacha. When we were putting up a bathhouse, a neighbor advised us to line the underground under the bathhouse with empty glass bottles, having first dug a hole in the shape of a cone. Along the slopes of this cone, lay the bottles with their necks down, simply drowning them in the ground. What does such a device provide: firstly, water flows down and does not accumulate under the floor, as a result - wooden floor is less susceptible to rotting, and secondly, the glass heats up when we heat the bathhouse, and retains heat for a long time - the floors in the bathhouse become warmer."
5. “Indeed, glass containers are quite often used in construction if they are available. If you have the desire and a sufficient amount of time and, probably most importantly, patience, then it can be mixed with screenings and poured into concrete. The most important thing is that the glass containers must first be crushed very well. The non-crushed option is not very suitable for use in concrete a good option. For grinding, as an option, you can use a concrete mixer filled with water so that when turning, glass fragments do not fly out of it.”

The construction industry uses concrete mixtures that, after hardening, have increased strength. To perform special tasks, various additives are added to concrete to change its characteristics. One of the common components is liquid glass for concrete. It shortens the drying time concrete mixture, increases the resistance of the monolith to moisture, acids, and elevated temperatures. It is important to mix concrete and glass correctly to ensure the required material performance is achieved. Let's take a closer look at this additive.
Why add liquid glass to concrete?Getting to know the material
Many people have heard that the construction industry uses an additive called liquid glass. However, not everyone has an idea of what it is. The ingredient in question is potassium and sodium silicates dissolved in water, derived from silica. Almost everyone has encountered an aqueous solution of silicates when using silicate glue for household purposes. The material is visually perceived as a viscous liquid with a whitish-yellow tint. Let us dwell on the manufacturing technology, according to which the material is classified by type.
General classification
Modern technology makes it possible to obtain the additive various methods. The component can be produced by high-temperature processing of silicon raw materials together with an aqueous solution of sodium hydroxide. The equipment allows you to obtain an ingredient with specified properties by sintering soda with quartz particles. You can also use the method of mixing silicon dioxide with an alkali solution.
Depending on the manufacturing features, two types of ingredients are obtained:
- sodium mixture, characterized by increased adhesion, adhesive properties, resistance to atmospheric factors;
- potassium composition, characterized by accelerated drying, as well as good resistance to elevated temperatures.
The performance characteristics of both types of materials are identical, but the sodium composition has a lower price.
Additive to concrete - sodium liquid glass Why add liquid glass to concrete?
The use of a silicate solution introduced into the concrete mixture at the preparation stage, as well as external treatment concrete surface changes the properties of concrete.
After liquid glass is introduced, concrete acquires additional characteristics:
- resistance to moisture penetration. Due to its increased water resistance, a monolith modified with a special additive is in demand for foundations and underground structures;
- resistance to elevated temperatures. This allows the use of modified cement composition for the manufacture of fireplaces and the construction of stoves, the masonry of which is exposed to open fire;
- the ability to harden in a limited time. With an increased concentration of sodium silicate in the working solution, the concrete mixture hardens at an accelerated rate, which is important for sealing various cavities;
- resistance to acids. The introduction of a silicate solution into a concrete composition increases resistance to aggressive environments, which is important for the use of concrete in the chemical industry.
To ensure the required characteristics, when mixing concrete with liquid glass, the proportions must be strictly observed.
Liquid glass in concrete - pros and cons
Just like all building materials, the additive has its advantages and disadvantages.
What does liquid glass give when added to concrete? Advantages of the additive:
- low price of building materials;
- low additive consumption;
- resistance to atmospheric factors;
- durability protective film;
- ease of use when introduced into concrete and surface application;
- good adhesion to mineral bases.
In addition, the silicate component has:
- increased hydrophobizing properties. As a result of creating a waterproof layer, moisture absorption is difficult;
- high antiseptic characteristics. The additive prevents the development of bacteria and impedes the growth of microorganisms;
- antistatic properties. The characteristics of the silicate additive prevent the accumulation of static electricity;
- ability to seal cracks on the surface. This ensures the array is moisture-proof;
- resistance to open fire, acids, and elevated temperatures. The processed material retains its structure and properties.
Along with advantages, there are weaknesses:
- accelerated crystallization of the modified composition when carrying out measures for waterproofing foundations;
- impossibility of use for treating the surfaces of buildings made of brick;
- insufficiently high strength properties of the protective film, which is destroyed under mechanical stress.
Among insulating materials liquid glass for concrete is released Despite its shortcomings, the additive is widely used professional builders, private developers, home craftsmen to solve an expanded range of problems.
Application of liquid glass in concrete - areas of use
Workers in the construction and repair industries actively use silicate solutions based on sodium and potassium. They increase the performance characteristics of the monolith, which allows it to be used for various purposes.
Areas of application of silicate modifier:
- sealing cracks and cavities through which moisture penetrates;
- external finishing of building walls to increase their moisture resistance;
- waterproofing of basement masonry;
- moisture protection basements, hydraulic facilities;
- cooking special compounds for priming concrete surfaces;
- construction of foundations for installation of heating equipment;
- production at industrial enterprises special types concrete;
- construction of foundations for various objects;
- protection of walls of residential and utility rooms from the development of mold, fungal colonies;
- processing of joints and internal surfaces of well rings.
Liquid glass sold in plastic canisters In terms of its characteristics, the component has practically no analogues when performing work related to waterproofing and impregnation. Properties silicate material allow us to provide reliable protection concrete structures from moisture, elevated temperatures, and aggressive environments.
How much liquid glass to add to concrete - proven recipes
Let's consider how much of the silicate component should be poured into the concrete mixture to perform various tasks.
For preparing modified cement mortars and concrete, use the following recommendations:
- masonry mixture for the construction of fireplaces and stoves is prepared from Portland cement and fine sand, maintaining a ratio of one to three. IN sand-cement mixture you should fill in 18–20% of the glass from the total volume of mixed components, then add water. All that remains is to mix everything thoroughly until smooth, and the finished solution can be used;
- to prepare a concrete base with moisture-resistant properties, fire-resistant characteristics and intended for domestic use, the concentration of the additive should not exceed one tenth of the total mass. This composition can also be used to waterproof home pools;
- To waterproof the joints of well rings and treat the internal surface, a composition consisting of Portland cement, glass, and sifted sand is prepared. It is very important to maintain proportions by adding ingredients in equal proportions. By gradually adding water, you need to achieve a creamy consistency.
Provided the proportions are observed, the concrete solution acquires the required properties.
Liquid glass as an additive for concrete We pour liquid glass correctly - the additive to concrete does not tolerate mistakes
Situations arise when the introduction of glass does not bring the expected result. This is due to the lack practical experience, non-compliance with proportions.
- It is prohibited to introduce a silicate additive into the prepared concrete solution. You must first mix the ingredients, then dilute the glass with water. Then you need to gradually pour in the solution, mixing thoroughly;
- control the percentage of added components, do not exceed the proportions tested in practice. This ensures that the required performance properties of concrete are obtained.
Remember that an increased concentration of silicate filler, as well as a decreased one, negatively affects the properties of concrete.
Adding liquid glass to concrete - operating rules
To ensure the required effect from using the additive, it is necessary to study the rules for working with silicate additives, as well as prepare the necessary tools.
Waterproofing with liquid glass For surface treatment of the concrete mass you will need:
- wide roller to speed up the application of the protective composition;
- brush for processing silicate mixture small areas and corner areas;
- metal brush for preparing the surface to be treated;
- a spray gun that allows you to apply material when performing work on an industrial scale;
- container for mixing ingredients and preparing special mortars;
- protective gloves protecting skin covering from contact with the silicate component.
General operating rules provide:
- Thorough cleaning of the treated surface from contaminants of organic and inorganic origin.
- Sealing deep cracks and leveling the surface using concrete putty.
- Layer-by-layer application of material using a wide roller, brush or industrial spray gun.
When the coating is applied in two layers, it penetrates 1.5–2 mm deep into the array. The modifying composition does not contain harmful components, however, you should wash the skin with water if the silicate solution gets on its surface. After completing the work, it is necessary to inspect and clean the tool from any remaining silicate mixture.
The supplement can be administered orally concrete mortar at the cooking stage. To do this, you need to gradually add liquid glass for concrete to the concrete mixer or container. The instructions for use must be followed to ensure the required concrete characteristics.
How to cover a concrete floor with liquid glass To prepare modified concrete composition You will need the following tools:
- a special attachment for the drill that increases the efficiency of mixing the components;
- a container for mixing components using a nozzle or a small-sized concrete mixer;
- Personal protective equipment that protects the skin and mucous membrane from getting the additive.
The algorithm for preparing a modified concrete composition involves the following operations:
- Dosing of ingredients in the required proportions.
- Adding an aqueous solution of a special additive to the concrete mixture.
- Preparation of the concrete mixture according to the recipe.
- Thoroughly mix the components until a homogeneous consistency.
When pouring liquid glass into concrete yourself, the proportions must be strictly observed. Exceeding the amount specified in the recipe will cause accelerated drying concrete with cracks. Adding a reduced volume of liquid glass to concrete will not provide the required performance characteristics.
Conclusion
To ensure the required performance characteristics of concrete, when pouring liquid glass, follow the proportions for concrete. Guided by the recommendations of professionals and following a recipe proven in practice, it is possible to ensure the necessary working properties of the monolith. Due to the low cost of the silicate additive, the cost of the concrete solution increases extremely slightly, and performance allow the use of modified concrete to solve a wide range of construction problems. Consulting professionals will help you avoid mistakes.
Currently, one of the alternatives to plain concrete is glass concrete. This building material is different from ordinary concrete greater strength, frost resistance and thermal conductivity. Today there are 6 types of glass concrete on the market, each of which has its own differences and features. The material can be made independently at home, and its properties will be the same. high level.
A little history
On the one hand, there is concrete, which causes pollution, in particular due to the cement used in its composition. On the other hand, there is glass waste that can be completely recycled using a complex and expensive process. The solution to placing glass in concrete was proposed by the Ellen MacArthur Foundation after a series of studies published in October 2016.
Concrete is one of the widely used building materials in the world. In the United States, where the study was conducted, 600 million tons of concrete were produced in 2015. However, it is one of the materials with the greatest negative impact on environment- because of the cement used to make it.
To reduce its carbon footprint, the concrete industry has begun using two main cement substitutes: coal ash, which is produced by burning coal, and slag, a byproduct of steel production. These substitutes have reduced carbon emissions by 25 to 40% per ton of concrete, increased strength and reduced costs.
But these replacements are not ideal solution: they contain heavy metals- mercury, which makes them potentially toxic. Producers and users remain dependent on fossil fuels:"As more and more more companies are trying to reduce their carbon footprint and use renewable energy, the use of fossil fuel by-products in their factories is increasingly seen as counterintuitive and counterintuitive,” writes Ellen MacArthur Foundation Ph.D.
At the same time, solving the problem of glass waste is becoming increasingly problematic. Americans fail to reuse glass after consumption - 11 million tons per year. Only one third is recycled and the rest goes straight to landfills. Although glass is 100% recyclable, the study says more American cities are abandoning their recycling programs - mainly for financial reasons: sorting glass is difficult and expensive.
General description and classification
Each building is a unique structure with features unique to it. Even if during construction it is applied standard project, it is necessary to take into account some factors, for example, the characteristics of the soil, the depth of its freezing, the humidity of the soil and air, the available wind and its strength. When taking these nuances into account, some adjustments will have to be made to the construction project.
So, if there is an increased seismic hazard in the area of the building, then it is necessary to increase the total footage and diameter of the reinforcement, and also reduce the distance of its tying. If the soil moisture at the site of the future building is too high, you will have to increase the layer of concrete near the reinforcement, slowing down corrosion. In some cases, such problems can be solved by replacing calculation material to another, which has more convenient and advantageous characteristics. You can make construction cheaper by equally replacing building materials with cheaper ones.
For example, alternative option An expensive foundation due to an increase in quantity can be the use of glass concrete. However, it is worth paying attention to the fact that it includes a huge group of building materials that differ in properties, so you need to be able to understand their classification and characteristics various types. You will also have to become familiar with the strong and weaknesses concrete before choosing a specific type.
Each type of glass concrete has its own properties and characteristics. Depending on this, it is worth starting from when choosing a building material.
Glass reinforced concrete
This type of concrete is called composite concrete, which is an analogue of reinforced concrete. IN in this case The metal reinforcing rod is replaced with fiberglass. Thanks to the replacement of reinforcement, composite concrete has a number of distinctive properties.
Currently, expensive metal reinforcing rods have been replaced by more budget-friendly ones. composite materials made from plastic, basalt fiber or glass. In construction, the greatest demand is for fiberglass reinforcement, which, although inferior to basalt in strength, is much cheaper. Main characteristics:
- Light weight.
- Basalt and fiberglass reinforcement are manufactured in the form of bundles, which are rolled into a 100 mm coil.
- Basalt fiberglass reinforcement has 100 times less thermal conductivity than metal, which is why it is not considered a cold bridge.
Glass composite material is not subject to various types of corrosion and is very resistant to aggressive environments, although experts recommend avoiding highly alkaline environments.
This means that the reinforcement does not change in diameter, even if the surrounding environment is humid. Metal material If the concrete is poorly waterproofed, it can completely collapse. Corroded metal reinforcement begins to increase in volume almost 10 times, which can cause the concrete to burst.
This makes it possible to safely reduce protective layer concrete blocks, reinforced with fiberglass. The large thickness of the protective layer is determined by the protection function steel reinforcement from high humidity, which impregnates the top concrete layer, thereby preventing all possible corrosion.
When the thickness of the protective layer decreases, together with the light weight of the reinforcement itself, the weight of the entire structure also decreases, without reducing the strength indicator. This reduces the cost of the material, the weight of the entire structure, and the load on the foundation. Thus, glass-reinforced concrete is inexpensive, warmer and stronger.
With the addition of liquid glass
Liquid sodium silicate glass is added to glass concrete blocks to increase resistance to high air humidity and high temperatures. In addition, the material is distinguished by the presence of antiseptic properties, so it is best used for pouring foundations on marshy areas, as well as during the construction of hydraulic structures:
- decorative ponds;
- swimming pools;
- wells and more.
To increase heat resistance, such blocks are used when installing boilers, stoves and fireplaces. In this case, glass is the connecting element.
Glass-filled material with fiber
Thereby universal material it is possible to produce monolithic blocks and sheet materials, which are currently purchased on the market under the brand name “Japanese wall panels”.
The characteristics and qualities of this building material may change under the influence of certain additional elements or depending on changes in the amount of dyes, acrylic polymers and other additives. Glass-filled concrete with fiber is a strong, lightweight and water-resistant material that has a number of valuable decorative qualities.
GRC consists of a fine-grained concrete matrix that is filled with sand, as well as lengths of glass fibers called fibers.
Litracon, or glass-optic concrete
The main material used in manufacturing is a concrete matrix, as well as oriented long glass fibers, including optical fibers. They pierce the block through and through, and the reinforcing fibers are located between them in a chaotic manner. After grinding, the ends of the optical fibers are freed from the cement laitance and can transmit light through them almost without loss.
Currently the material is expensive. In one square meter fiber optic concrete will cost about $1,000. But experts continue to work to reduce costs. Construction material has glass fittings. You can imitate it yourself at home if you find optical fiber and be patient, but in this case it will not be a construction material, but, most likely, a decorative one.
With broken glass
Thanks to this type of concrete, you can significantly save on filling materials by replacing sand and crushed stone with broken glass and closed glass containers:
- ampoules;
- balls;
- tubes.
Crushed stone can be replaced with glass 100%, without losing strength and weight finished block will be much smaller than conventional glass concrete. Beer bottles inside concrete are suitable for making this material at home.
With binder
Glass concrete with glass in the form binder used for industrial production.
At the beginning of the process, the glass is sorted and finely crushed, after which it passes through a screen and is separated into fractions. Glass particles, the size of which is more than 5 mm, are used for the manufacture of glass concrete as a coarse aggregate, and smaller grains act as a binding powder. If you have the opportunity to finely grind glass at home, you can make concrete yourself.
For decorative purposes
Glass concrete for decorative finishes used in different ways. A typical surface treatment procedure can be applied, sandblasting or polished with diamonds. Glass particles are mixed monolithically with concrete, but more often they are applied to the surface fresh concrete. This method is used to add uniqueness to the flooring of a room.
A logical assumption would be that decorative glass concrete would be made from recycled glass bottles, but that's not true. Recycled glass has too much contamination. For this purpose, objects such as windows, glasses and mirrors are used.
Manufacturers do not use “dirty” glass containers or glass with stickers. Recycled glass is sorted by color, but it can also be mixed together. In any case, it melts and crushes, rather than being extinguished by water (which breaks the glass badly). The material is then sorted by size and the edges are blunted.
Glass concrete can be purchased at 20 various colors, the most expensive is red. For one bag you will have to pay 150 dollars.
Currently, glass concrete is widely used, and thanks to its unique characteristics, it is in demand in the manufacture of finishing panels, fences, gratings, partitions, decor and other products. If you master the technique of making glass concrete with your own hands at home, you can save a lot of money and create unique design in my house.
Concrete has been widely used in construction for many years due to its resistance to deformation and durability, but the material also has some disadvantages, the most important of which is low tensile strength. Most often, this problem is solved with metal reinforcement, but in our time more progressive solutions have appeared. You can make glass concrete with your own hands, and the properties of the material will be at the highest level while reducing the weight of the structure.
In the photo - the use of fiberglass allows you to give even thin concrete elements unsurpassed strength
Main types of materials
Let us immediately note that the concept of glass concrete refers to a whole range of variations; we will not consider all of them; we will only get acquainted with those that are most often used and with which you can work independently. Each type has its own characteristics, which determine certain properties of the material.
Composite concrete
The second name for this option is glass-reinforced concrete. It is very similar to conventional reinforced concrete options, but glass concrete technology involves the use of metal fittings fiberglass rods.
To explain all the advantages of composite reinforcement, let’s compare it with conventional metal reinforcement:
| Metal | Fiberglass |
| When exposed to moisture, it corrodes, causing the frame to collapse, reducing the strength of the concrete structure. | It is absolutely not afraid of moisture and can withstand its effects for a long time. |
| The large weight of metal-reinforced structures imposes many restrictions on construction. | Products made from glass concrete weigh much less, as a result of which they can be used almost anywhere. |
| Enough high price reinforcement makes the project much more expensive to achieve High Quality you need to spend significant amounts of money. | The price of composite reinforcement is much lower, which makes it more affordable than conventional metal. |
| The weight of the metal is quite large, which creates inconvenience during work and loading and unloading operations. | Fiberglass rods weigh 5 times less with the same diameter. |
| Transporting reinforcement is very difficult due to the large length of the elements. You have to hire freight transport. | The material is rolled into coils about 100 meters long, and the weight of one coil does not exceed 10 kg. It can also be transported in the trunk of a passenger car. |
| The metal has high thermal conductivity, as a result of which the rods serve as unique cold bridges in the structure. | Fiberglass conducts heat 100 times less than metal, such structures are much warmer. |
Such reinforcement is superior to metal in all respects, which is why it is very widely used in modern construction
Another important advantage is that composite rods are 2.5 times more tensile strength, which allows the use of products of smaller diameter without losing the strength characteristics of the structure.
Work on creating a reinforcing belt of this type is much simpler and faster due to a number of reasons:
- Light weight material.
- Easy connection - using plastic clamps that securely fix each node.
- In winter, metal is very cold, while fiberglass does not freeze.
The work of laying a composite armored belt is much simpler than when using metal
Important!
It is worth remembering that the strength properties of fiberglass are much higher, so you can use reinforcement of a smaller diameter without losing strength.
Glass reinforced concrete
This glass concrete has a number of differences, the main one of which is the use of fiberglass as a filler, which determines the high performance properties of the material.
Fiberglass is resistant to alkalis and other adverse influences
The main advantages of this option include the following factors:
- Versatility: this way it is possible to produce both panels and blocks or light and durable cladding sheets. The scope of application is very wide.
- Ease: the composition includes fine-grained concrete mixed with sand in a ratio of 50/50 and chopped fiberglass.
- Strength fiber-reinforced concrete: it is twice as resistant to compression plain concrete, when stretching and bending, it is 4 times stronger, and the impact resistance is even 15 times higher.
- With the help of various additives: plasticizers, dyes, water repellents, the properties of concrete can change significantly.
But it is worth noting that the production of such material is a rather complex process, and high quality and reliability can only be achieved in a factory environment.
Fiber-reinforced concrete sheets have a unique structure and can even be used as a final finish
Concrete with the addition of liquid glass
This option cannot be called glass concrete in pure form, however, it is worth considering it, since liquid glass is used in production. This silicate-based component gives the material high moisture resistance properties and increases resistance to high temperatures.
In addition, liquid glass has pronounced antiseptic properties, due to which it is often added during construction in swampy areas, where dampness has a particularly strong effect on structures.
Liquid glass gives concrete the highest properties of resistance to both moisture and high temperature
Instructions for preparing concrete are as follows:
- First the concrete is prepared the right brand, but do not make it too liquid.
- Next, liquid glass is diluted with water in the proportion specified in the instructions on the package.
- The prepared solution is added to concrete in a ratio of 1:10, after which the composition must be thoroughly mixed before use.
Important!
The water that is added to liquid glass is not taken into account when preparing concrete, since it is used to maintain chemical reaction, making the surface resistant to moisture.
It is important to mix the solution thoroughly, then the entire surface will be protected from moisture
Sometimes a simpler method is used: impregnation of the surface with a solution of liquid glass. But in order to achieve the best protection, it is better to apply another layer of solution with liquid glass for concrete on top, especially since it hardens quickly enough, so the time required for the work will not increase.
Everyone knows that cutting reinforced concrete with diamond wheels, as well as diamond drilling holes in concrete, is associated with many difficulties. But the use of fiberglass elements simplifies these complex work: the material lends itself much better, and crowns and discs wear out less quickly.
Concrete with fiberglass is much easier to drill
To understand the issue even better, watch the video in this article; it clearly shows some of the nuances under consideration. In general, we can confidently say that fiberglass elements are the future, and glass concrete will be used more and more every year.
) is one of the modern universal building materials. For designers and architects, glass concrete provides almost unlimited creative possibilities.
Glass concrete has established itself as an excellent product that has made a great contribution to the aesthetics, technology and economics of the construction industry. Essentially, glass concrete is a collective name for a group of materials that can be used to create various designs. Glass concrete has been used in global construction practice since 1969 and has been successfully used all over the world since then. Over the past years, it has significantly expanded the scope of its application and has significantly improved. Glass concrete structures are widely used in Japan. South-East Asia, countries of the Arab East, USA, Europe. In Russia, the scale of its production and use is much smaller compared to other countries. The reason for the creation of this material was the need to improve conventional concrete.
