Sand is free-flowing natural material, obtained as a result of natural destruction of rocks under the influence external factors. May contain small amounts of various impurities. It is used in almost all types of construction. To properly mix the solution, you need to know the density of the sand, since the proportions of the other components depend on it. It also affects the volume of purchases, for example, for arranging a cushion for the foundation.
What is density and what does it depend on?
Density shows how many grains of sand in kilograms fit into 1 m3. It is measured in kg/m3, sometimes in t/m3 or g/cm3 (this indicator affects). But this value is not always constant, as it can change depending on the following conditions:
1. Grain size. It can be fine-, medium- and coarse-grained. The larger the grain of sand, the lower the density, and, conversely, small ones fit more tightly. Coarse- and medium-fraction sands are used for manufacturing building materials and masonry mortars, and fine-grained ones are used for the production of dry construction mixtures.
2. Porosity. Shows the number of voids. The high porosity option has lower density. If it is loose, then the value is 47%, if compacted - 37%. The degree of porosity decreases when sand grains are saturated with moisture, as they are enveloped in water and the voids between them disappear. It also decreases after transportation, since during movement everything is compacted due to vibration. Different fractions have different degrees of porosity. For construction sand made from large and medium grains it is 0.55, for fine sand it is 0.75. The denser it is laid, the greater the load from the foundation it can withstand and distribute it more evenly.
3. Humidity coefficient. You should definitely check the degree before purchasing. The more water it contains, the lower the density. The weight of 1 m3 of wet sand differs significantly from the same amount of dry sand.
4. Impurities. Depending on their volume, the density of sand kg/m3 also changes. It may contain clay, dust, salt, gypsum and much more. Density pure material is about 1300 kg/m3, with clay impurities - 1800 kg/m3. To remove contaminants, it is washed, but because of this, the cost increases significantly.
Types and prices
There are several types of densities:
- true;
- bulk (medium).
The first type is also called specific gravity and is also measured in kg/m3. True density shows how much is in one cubic meter of bulk building material, without taking into account the voids between the grains. It is calculated experimentally in laboratories. Its value for non-metallic sand rock is 2500 kg/m3.
Bulk density shows the quantity in one cubic meter, taking into account voids and gaps. Its value is always less than the true value. To measure it, you will need a 10 liter bucket. Sand in its usual uncompacted state is poured from a height of 10 cm from the edge of the container until a slide appears above it. As soon as the bucket is filled, the excess is leveled with a metal ruler, without compacting the sand, after which the container is placed on the scale. The result obtained must be divided by the number 0.01, which means the volume of the bucket, converted to cubic meters. For example, sand weighs 16.5 kg, it is equal to: 16.5/0.01 = 1650 kg/m3. In this case, it is convenient to use the formula P=M/V, where P is density, M is mass, V is volume. And, conversely, knowing the compaction indicator, it is calculated how much the bulk building material weighs, for this it is multiplied by the volume of the container - M = P * V.
The true density of construction sand is a constant value. The average value is used for calculations. Prices vary depending on its type, purity and fraction size. Uncleaned is noticeably cheaper than washed. Therefore, if a small batch is required, you can purchase unwashed sand and clean it of impurities yourself, especially if it is needed for the construction of a non-load-bearing structure. If you need it for making a foundation, you should purchase only clean and quality material. Clay and other impurities reduce the degree of adhesion of sand grains to cement, which is why the strength grade of concrete decreases.
Table with prices at which you can buy construction sand:
When choosing sand, you should take into account: the lower its density, the more binding powder is required to fill the voids between the sand grains and connect all the components, as a result, the cost of the mortar increases.
The degree of radioactivity of most bulk building materials is first, but it is better to check the quality certificates, especially if it will be used to build a house, in which case it should only be class one.
Humanity has been using sand for construction needs for a long time; without it, one certainly cannot build a house. It is actively used in dry construction mixtures, which are sold in stores or as a component for preparing cement mortars. Construction sand is used depending on its density, e.g. individual species are used to create others in order to make a concrete screed.
Sand is a non-metallic, free-flowing building material. As a rule, this is a mixture of grains measuring 0.14-5 mm, which were formed during the natural destruction of rocks. There are several. They are characterized by a different content of small particles of clay or simply dusty elements.
The purest of them and the highest quality is river sand. Sea water is worse, since it already contains salts, from which it must be purified. Quarry sand and mountain sand are distinguished by the presence of undesirable clay, which means the quality of the product is lower. Sand mainly has the following composition: quartz and also impurities in the form of silicates and the same clay.
To characterize this building material, there is such a thing as sand density. It is estimated by the porosity coefficient. For example, fine-grained varieties have an indicator of 0.75. The density of construction sand and its quality are always determined by the presence of clay in it. Builders love to work with a uniquely pure river product. It has a density of 1.3 tons. cubic meter. The density of sand with clay content is higher and is already 1.8 tons. In the same volume.
This material has served as the basis for cement and concrete compositions. It is in great demand when laying highways, blowing glass products and in agriculture.
In construction, the concept of density is of fundamental importance, which is the ratio of the mass of sand to its volume; it has units of measurement: g/cm3 and kg/m3. Natural sand is 1300-1500 kg/m3.
For bulk building materials, this indicator is variable and depends on the degree of compaction. This means that the same amount of product occupies different volumes. The density of sand is invariably dependent on humidity, and any changes in it affect the bulk density. As humidity increases, sand grains become covered with a layer of water and, accordingly, the volume of sand increases sharply. It is sand that is taken into account during humidity fluctuations when calculating the dosage of sand according to the required volume. If this factor is not taken into account, mortar will not have the necessary margin of safety and, in general, the engineering design will be of poor quality.
Nowadays it is mainly used; it is extracted simply by washing quarry sand. This is done in this way: clay and dust are washed out of it with a large volume of water.
The density of construction sand also depends on the structure of the grains. For example, a high indicator directly indicates that it contains dense, especially strong and frost-resistant grains. It is this material with an increased coefficient that is indispensable for construction in permafrost conditions. It is the basis of high-strength concrete with excellent frost resistance.
Density in a loose state is characterized by 1500 kg/m3, but can increase to 1700 kg/m3. It is characterized by the best hygienic characteristics and is a washed and calcined dry natural material. When used in construction, high hygienic characteristics of the home are ensured. Density quartz sand- this is very important parameter, which is taken into account when conducting construction work.
Sand is a bulk material. It is difficult to measure its true density - it is almost impossible to remove gaps between grains of sand. For this reason, the concept of bulk density of sand is more applicable to sand. This is the average value of the weight of the material per unit volume.
Concept and meanings
The determination of the bulk density of sand hides the value of the dry mass of the material per unit volume, measured in cubic meters or cubic centimeters.
There are many types of sand by origin and fraction. Small grains of sand fit more tightly into the volume than large ones, therefore their mass is much greater. And vice versa.
Thus, sand extracted from the river is usually smooth and polished and has a dense structure. Its weight per cube averages 1500-1600 kg/m 3 according to GOST 8736-93. Sand grains from a quarry are often porous with sharp corners and edges; these weigh much less - about 1300 kg/m3.
Factors determining density
The bulk weight of sand depends on several factors:
- The fraction and shape of sand grains determines the density of the bulk material to a greater extent. The larger the fragments, the greater the distance between them and vice versa. Round and square grains of sand take up more space than flat ones.
- Breed of origin. The denser the mineral from which the sand is formed, the greater the mass.
- Remains of soil and organic impurities also affect the bulk mass of sand. Cooking technology mortars involves the use of purified fine filler, so this parameter can be adjusted by washing or sifting the fill.
- Humidity after washing or sand mining. Water penetrates the pores of sand grains and increases their weight. The bulk density of dry sand is up to 30% less than wet sand. As it dries, the mass decreases and the volume increases.
- Sand compacted during placement has much more high density per unit volume than poured in the normal state.
The value of mass per cubic meter can be clearly seen in the table of bulk density of natural sand:
Calculation of changes in volume and mass
Sand is delivered to the construction site in different forms: dry or wet, river or quarry. It may not be used immediately: the material is used as needed. If the embankment is stored under open air, grains of sand constantly change humidity depending on weather conditions. Technologists have to take these factors into account before preparing working solutions and backfilling pits.
Since the bulk density of fine and coarse sand is constantly changing, compaction coefficients are used to determine the actual mass of the volume without weighing. Some of them are reflected in the table:
The average density of the material is multiplied by the coefficient to obtain the desired result. The table shows the most popular values of kу.
The bulk compaction coefficient of sand does not guarantee an accurate result - the error can be 5 percent or more. The only reliable way to determine the mass of a unit volume of material is weighing, which is not always possible or convenient. Professionals can use any of available methods determining density on site.
If you plan to build a house, then after creating the project, the issue of purchasing materials comes to the fore. To calculate how much sand to buy to mix the required volume masonry mortar or concrete mixture, it is necessary to know the density of the bulk component. This indicator significantly affects the strength parameters of structures and buildings. The conversion of mass to volume (and vice versa) is also carried out because the price of the material is indicated differently: per weight or volume unit.
What is density and what does it depend on?
This physical characteristic substance, showing the mass of its unit volume and expressed in g/cm3, kg/m3, t/m3. Sand, like all bulk materials, has this peculiarity: depending on conditions, the same amount of it can occupy a different volume. The density of construction sand is influenced by the following factors.
1. Grain size (fineness modulus). Sand is a mixture of particles ranging in size from 0.14 to 5 mm, formed naturally during the destruction of rocks. How smaller size grains and the more homogeneous the composition, the denser the sand. Coarse- and medium-grained material is used for the production of concrete, fine-grained - for cement mortars, fine-grained (pulverized) - for fine construction mixtures.
2. Porosity and level of compaction. They characterize the number of voids in the granular substance. In a loose state, construction sand has a porosity of about 47%, in a dense state - no more than 37%. Looseness is reduced due to saturation with moisture, vibration, and dynamic influences. Porosity is assessed using a special coefficient e: for fine-grained sands of dense composition it is about 0.75, for coarse and medium-grained sands it is 0.55. The compacted sand mass takes on fairly high loads and well distributes the stress that occurs in the foundations.
3. Humidity. Typically, reference books give the density at normal level humidity, regulated by GOST. When purchasing, you should take into account that the weight of a cubic unit of raw material differs significantly from the theoretical indicator. When humidity increases from 3 to 10%, sand grains are enveloped in water - due to this, the volume increases and the density, accordingly, decreases. With further moisture saturation (up to 20%), water displaces air and fills the voids between the grains - while the weight of the cubic meter increases.
4. Presence of impurities. Sometimes they contain particles of clay, dust, salt, mica, gypsum, humus, crushed stone, and stone chips. They affect the quality characteristics of the building material: if for clean sand it averages 1,300 kg/m3, then for clay – 1,800 kg/m3. Sand can be cleaned by washing with water, but its cost increases.
Types of density
Construction sand can be characterized using different indicators of its volumetric weight: theoretical and actual.
1. True (formerly called specific gravity). This is the mass of a cubic meter in an absolutely compacted state, without taking into account the air spaces between the particles. The true indicator is determined in a complex laboratory way; its value corresponds to the weight of a cubic meter of solid non-metallic sand rock - approximately 2500 kg/m3.
2. Medium (bulk). When determining it, it is taken into account that the calculated volume includes not only grains, but pores and voids that fill the spaces between them. The average is usually lower than the true value.
To independently determine the average density, use a 10 liter bucket. Sand is poured into it from a height of 10 meters until a slide is formed - it is carefully cut horizontally at the level of the top edge of the bucket. The material placed in the container is weighed, and then its density in kg/m3 is calculated: divide the mass in kg by 0.01 (the volume of the bucket in cubic meters).
The true value is a constant value and has an auxiliary value. In order to competently conduct construction, make practical calculations and evaluate the quality of the purchased material, it is more important to know average. For example, if a cubic meter weighs less than 1300 kg, this indicates a large number of voids and requires filling them with a binder. The cost of materials increases, making construction more expensive.

As you have already noticed, on the Internet it is quite difficult to find a clear answer to a specific question: what is the density of sand or its specific gravity. A search engine, such as Yandex or Google, provides a lot of information. But all of it is rather of an “indirect” nature, rather than precise and understandable. The search engine selects various mentions, fragments of phrases, lines from large and obscure tables specific gravity building materials, in which the values in different systems units. “Along the way” it “falls out” on websites a large number of"additional" information. Mainly: by types and varieties of sand, its use, application, origin, mineralogical composition, color, size of solid particles, color, impurities, extraction methods, cost, price of sand and so on. Which adds uncertainty and inconvenience to normal people who want to quickly find an accurate and understandable answer: how much is the density of sand in grams per cm3. We decided to “correct the situation” by collating the data on different types sand into one general table. By excluding in advance what we think is “unnecessary” or “related” information general. And by indicating in the table only the exact data, what is the density of the sand.
What is the density of sand or its specific gravity ( volume weight, specific gravity - synonyms)? The density of sand is the weight contained in a unit of volume, which is most often considered to be cm3. The question is completely objectively complicated by the fact that sand itself has many types, differing in mineralogical composition, the size of the fraction of solid particles in the sand, and the amount of impurities contained. Impurities in sand can be clay, dust, crushed stone, stone chips and larger stones. Naturally, the presence of impurities will immediately affect the density of sand that will be determined by laboratory methods. But most of all, the density of the sand will be influenced by its humidity. Wet sand is heavier, weighs more and immediately significantly increases the specific gravity per unit volume of this material. What is associated with its value when buying and selling. For example, if you want to buy sand by weight, then its sale should be tied to the so-called normal humidity, determined by GOST. Otherwise, if you buy wet or wet sand, you risk greatly losing out on its total quantity. In any case, for the consumer, it is much better to buy sand measured in units of volume, for example in cubes (m3), than in units of weight (kg, tons). The humidity of the sand affects its density, but has a very slight effect on the volume. Although there are some “subtleties” here too. Wet and wet sand is more dense and occupies slightly less volume than dry sand. Sometimes this needs to be taken into account. The specific gravity of the sand contained in the selected volume, that is, the density, will be significantly affected by the “way of laying” it. Here, it is meant that sand of the same type can be: in a state of natural occurrence, be under the influence of the suspended influence of water, be artificially compacted or simply poured. In each case we have absolutely different meanings, how much is the density of sand of this type. Naturally, it is difficult to reflect all this diversity in one table. Some data must be sought in specialized literature.
Among all the numerous options for the density of dry sand, only one is usually of practical interest to site visitors - bulk density. It is for this that we present the values of the specific gravity of dry sand in the table. It is useful to know that there is also another density - this is the true density of dry sand. How to define it? It is determined by laboratory methods or calculated using a formula. Although, it is more convenient to use reference data in a special table. The true density of dry sand gives us a different specific gravity - theoretical, which is always much higher than those values of the specific gravity of dry sand that are used in practice and are considered technological characteristics material. With some reservations, the true specific gravity of dry sand can be considered the density of solid particles (grains) included in its composition. By the way, when determining the bulk density, and therefore the technological specific gravity of dry sand, the grain size also plays some role. This characteristic of the material is called grain size. IN in this case in this table we are considering medium-grain dry sand. Coarse-grained and fine-grained are used less frequently and their specific gravity values may differ slightly. Not only the grain size, but the mineralogical composition of this bulk building material can vary. This table shows the bulk density of a material consisting primarily of quartz grains. Quantity and weight are measured in kilograms (kg) and tons (t). However, let's not forget about other types of material. On our website you can also find more specific information that is rarely found on the Internet.
