How many tons of sand in a cube: tables, examples of calculations

How to accurately calculate the required amount of sand

In order to accurately convert cubes of sand into tons or tons into cubes, it is necessary to know exactly the density of a given material, provided it is relatively stable compaction and a given volume. Accurate determination of the physical characteristics of sand is possible only under laboratory conditions, besides, the moisture content and compaction of sand constantly fluctuates depending on weather conditions and the method of its development, therefore, an accurate mathematical calculation is practically impossible. At the same time, the high cost of laboratory tests is unprofitable in relation to the error of averaged calculations. That is why it is customary in construction to carry out averaged calculations with a sand density of 1600 kg / m3 at a moisture content of 5-7%.

More than converting tons of sand into cubes is the problem of determining a sufficient amount of material, taking into account its compaction, because in the process of development, transportation and storage, the volume of sand changes significantly. Therefore, when purchasing, a coefficient of 1.1-1.27 is usually introduced, taking into account these features, i.e. if, according to calculations, you need 10 m3, then it costs 11-13 m3 to purchase, depending on the direct purpose of the material and the method of its storage.

Why know how many cubes in a ton of sand - specific gravity

Almost all building materials are both artificial and natural. Speaking about the latter, it consists of grains of 0.16-5 mm in size, and its bulk density is in the range of 1300-1500 kn / m3.

Whichever type of sand you choose, you need to know that it has one very good property - to absorb moisture, removing it from other finished products, while increasing its flowability. It is logical that if the volume changes, then the bulk density itself changes, which in turn depends on how the humidity changes.

If, for example, the humidity fluctuates in the range of 3-10%, then this material differs from dry in its density. It should be understood that a grain of sand, which is covered with a layer of water, increases in volume, and this leads to the fact that the density of the sand increases.

This suggests that when calculating construction work, it is worth considering this (bulk density) and knowing how the density changes with increasing humidity. It is the quality level of sand that depends on its density index.

The density of different types of sand, such as river, quarry or construction sand, will differ slightly from each other.

This is a very necessary characteristic, especially when it comes to a professional construction site, since this property affects the strength of the object, respectively, its service life.

The density of sand is already a known figure and you do not need to calculate it, but in order to calculate the volume of sand in a tone, you need to determine its mass. The calculation is carried out according to the formula m = V * p. Obviously, v is the volume of the sand and p is the density.

The density of sand is of two types:

1. Bulk.
2. True.

True and bulk density

This value is influenced by some factors that should be taken into account:

• the amount of impurities in the material itself (clay, dust, debris);
• immediate moisture level. A fairly wet factor, it is he who has an effect on the density. If the moisture content increases to 10%, then the density of the sand decreases, as different lumps form in it. But in such a situation, the volume increases;
• the size of the sand particles.Since sand consists of small grains, to take into account its density, you need to know the fraction of the material;
• you need to take into account the type of sand, which depends on where the sand is mined.

For more information on determining the density of sand, see the video:

Influence of impurities and temperature on the weight of water

From the point of view of physics, the specific gravity of the liquid is also important. The amount of a substance of interest that is placed in a volume (in 1 of its unit) or, if translated into a scientific term, the mass of a unit of volume, this is the bulk density, or, to put it another way, the specific gravity. This value is measured in kg / m3 or in tn / m3 or gp / cm3.

The table below clearly demonstrates the direct effect of temperature and organic impurities on weight. So in one cube, liquids in different states, there is an unequal specific gravity. The data was taken from a handbook of physical properties and materials.

Now you know the true weight of water in different conditions and under different conditions. And after doing some simple calculations, you can convert it to the desired units.

How to determine how much a cube of sand weighs: material characteristics

Many owners of country houses are trying to calculate how much sand is in one cube. This indicator is especially relevant for suburban construction, affecting such serious arrays of work as the construction of a building or the arrangement of the courtyard and the local area. How much does 1 cube of sand cost with delivery - one of the burning questions of any person who undertakes independent construction or is concerned about the purchase of material for hired workers.

Depending on how many kilograms of sand are in a cube, the basic proportions of the concrete mixture will be calculated. This point is very important, since an incorrect calculation will lead to a violation of technology and serious consequences.

Sand is used for a wide range of construction works

Why is it so important to determine how many cubes of sand are in 1 ton

An indicator reflecting how many kilograms in 1 cube of sand, with erroneous calculations, can cause many difficulties:

• violation of the formulation of a mixture of concrete;
• incorrect consistency of the finished solution;
• loss of adhesive properties;
• poor concrete quality;
• disturbances in the solidification process;
• decrease in the strength of concrete;
• premature destruction of a structure made of cement mortar.

For this reason, it is very important to determine not only how much sand is in 1 cube, but also how much material is contained in this volume.

When calculating the required number of cubes of sand, take into account its specific gravity

The indicator reflecting 1 cube how many kg of sand is contained in a specified volume is called specific gravity or specific gravity. This measure, applicable to bulk materials, is in the range of 1500-2800 kg / m2. Accordingly, you can now estimate how many kg are in a cube of sand.

The specific gravity of a material can be influenced by various factors, including:

• composition of minerals;
• grain composition;
• size of fractions;
• humidity level;
• the percentage of compaction;
• impurities.

Sand density

Today, many are concerned about the cost of a cube of sand, but few know that the final price is influenced by the characteristics of the material, one of which is density. Sand, like crushed stone, belongs to the category of bulk materials. Its density depends on the air spaces that form between the solid particles.

The density of sand is:

• technological;
• real;
• bulk - represents the ratio of the specific gravity of sand to the volume occupied by this material.In this case, the volume includes not only solid particles of sand, but also all the pores, as well as voids in the composition of the embankment (taken as a basis for determining how many cubes of sand are in a bag or bucket);
• true or conditional - the value is considered as the limit of the ratio of the specific gravity of the material to the volume it occupies, minus all pores and voids present in the embankment.

The density of sand varies within 1.3-1.8 t / m ?, and is equal to 1.3 t / m? for river sand, and 1.4 t / m? - for a career.

The density of construction sand is 1.3 to 1.8 tons per 1 cubic meter

Sand fraction size

How many cubes of material are in a bag of sand can be determined taking into account its grain composition. To do this, it is enough to sift the grains of sand using special sieves. As a result, you will be able to determine the level of content in the material of gravel particles with certain dimensional data. Usually, the size module of the material is used in calculations.

Table 1. Sand size modulus:

If you have fractions in front of you that exceed 2.5 mm, most likely you are dealing with quarry or river sand, how much a cube of material weighs in this case will depend on water demand.

According to the particle size, the material is divided into 2 classes:

• I - more than 1.5 mm;
• II - with any dimensional data.

The class of material and the size of its fractions determines how much 1 cube of sand costs for construction work.

There are three sizes of sand grains - fine, medium and coarse

How to calculate weight?

They sell the material on wooden pallets. So it can be packed more tightly, and loading and unloading operations can be carried out using a crane or hoist. The permissible weight of a pallet of bricks according to building codes should not exceed 850 kg, taking into account the weight of the pallet itself (about 40 kg), although in reality it is usually larger. It is convenient to count the items on a pallet, as they are stacked in the form of a cube.

The weight of a cubic meter of an ordinary single solid brick is about 1800 kg, a slightly smaller volume is included on the pallet, weighing up to 1000 kg. One cubic meter of one and a half material weighs about 869 kg, about the same volume fits on a pallet. The weight of a cubic meter of double bricks reaches 1700 kg, about 1400 kg can be stacked on a pallet. That is, the weight of one pallet of different products will not be the same.

It is impossible not to mention the so-called white brick, it is made from quartz sand and lime, so it is on sale under the name silicate. In the 20th century, it became very widespread. This material is much denser than the previous one, it is distinguished by even greater sound insulation. White bricks are also not the same. A solid single sand-lime brick weighs about 4 kg, one and a half up to 5 kg. Sometimes it is hollow, its weight: single about 3 kg, one and a half almost 4 kg, double more than 5 kg. It can also be facing, such a brick is also hollow, usually one and a half, less often double. The first weighs about 4 kg, the second almost 6 kg.

You can also calculate the approximate mass of the pallet of other types of sand-lime bricks. And, of course, the weight of 1 cubic meter of material is not equal to the weight of the pallet: a full-bodied single one will weigh about 1900 kg, one and a half more than 1700 kg. Single hollow is already more than 1600 kg, one and a half about one and a half tons, double about 1300 kg. Facing silicate brick, which is made with voids, is somewhat lighter: one and a half about 1400 kg, double about 1200 kg. But there are always discrepancies associated with some technological differences between products from different manufacturers.

Sometimes you need to know the mass of brick fighting when dismantling walls or even entire buildings, this issue becomes relevant. A cubic meter of battle cannot be translated into pieces. So how much does a broken brick weigh? The volumetric weight (kilogram / m³) is used for calculations. The accepted norm for calculating the weight of brick breakage is 1800-1900 kg per cubic meter.

A summary table by brick weight is in the next video.

Let’s block ads! (Why?)

1m3 = 1.43t = 1430kg

* Data obtained according to laboratory studies, passports to 16 varieties (types) of sand taken in 6 quarries. The conversion factor is 1.43 - valid throughout the territory of St. Petersburg, and most of the L.O.

To determine how many cubes are in a ton of sand, you need to know its density. And it is equal to 1.43. Further, using the formula: V = m / p, where values: V - volume of sand, m3; m is body weight, t; p - constant 1.43; you can calculate the volume of sand depending on the specific mass values.

Example 1. You have 0.3m3 of sand. How much is a kilogram? According to the formula: m = V * p, we consider: 0.3 x 1.43 = 0.429 t x 1000 = 429 kg

Example 2. In one cube of sand - 28.6 bags, 50 kg each. Total: 1 m3 = 28.6 x 50 = 1 430 kg

Influencing factors

Good river sand is delivered to customers in a more or less standardized form. However, it still experiences a number of influences that directly affect the mass of a particular volume. It is quite obvious that the higher the humidity, the higher the density. Rather, the so-called bulk density of a bulk substance depends on the degree of moisture. Experienced builders and delivery workers know very well that storing sand outdoors in winter increases its weight by 10-15%.

The specific indicator depends on the amount of snow and ice that has formed on the stored sand

You should also pay attention to the grain size. This indicator, influencing the trading parameters of the material, is itself determined by the geological and climatic parameters of a particular deposit.

It is customary to divide sand by size module into 3 main categories:

• small (no more than 1.5-2 mm);
• medium (from 2 to 2.5 mm);
• large (over 2.5 mm).

Sand raw materials from reservoirs have increased roundness. After all, both water and friction act on the grains of sand. Under mechanical action, flakiness grows, which, however, affects, to a greater extent, not the weight, but the strength of the sand. For private buildings and small paths, flakiness can be ignored. But in case of large-scale construction, it cannot be ignored.

The bulk density of sand is determined primarily by compaction. Shaking increases the compaction. In the process of pouring from one container to another, during unloading it is reduced. Accordingly, the compaction ratio can vary from 1.1 to 1.3. But one more nuance must be taken into account - various impurities may be present in the composition of the sand; to take everything into account as accurately as possible, you need to buy sand on a warm, dry day.

Materials science distinguishes the following types of sand density:

• real;
• technological;
• bulk;
• true (it is conditional).

The bulk density is determined by dividing the weight of the raw material by its volume during the research process. In this case, any cavities and air-saturated gaps are taken into account. The relative density denotes what is the ratio of the mass and volume of a substance after the highest practically used state. But the sand is free-flowing, and therefore, under real operating conditions, it does not reach the greatest compaction. To achieve this, professional presses are used.

The true density will definitely surpass all other parameters. In many cases, it turns out to be twice as high.

However, from a builder's point of view, only bulk density is of real importance.

The bulk density of the sand is determined taking into account the modulus of the size or the grain size composition. The measurement is carried out by sifting the starting material through a sieve with heterogeneous cross-sections of the passages. This method only seems primitive - in fact, it is quite accurate. The content of all kinds of impurities in the composition of the sand, primarily gravel, is established without problems.

Important: the section of grains of sand affects not only the mass, but also the so-called water demand

Typical river sand grain size is 0.3-0.5 mm.The absence of various inclusions or their extremely limited number means that a cubic meter of sand from the river weighs more than the sand raw materials from the quarry. When assessing humidity, one must understand that it affects both the specific gravity and the bulk density (albeit to a somewhat lesser extent). This information is enough to estimate the required amount of raw materials for various situations. For more information, contact qualified consultants.

Basics of calculating the tonnage of sand in m3

When working with a translation from one quantity to another, it should be remembered that the fact how much a cube of sand weighs is influenced by two parameters:

• compaction and moisture of the material;
• density of raw materials.

Fine-grained open-pit sands contain many impurities that strongly compact the raw material. In this case, the density of the material will be in the range of 1700-1800 kg / m3.

To determine how much a cube of sand weighs, you need to multiply the density of the raw material by the volume.

Coarse sand has a density of 1400-1600 kg / m3. The weight of any bulk material is affected by its moisture content. According to the standard, the moisture content of the sand should be about 6-7%. If this indicator varies within 20%, then the mass of the entire material will exceed the calculations by about 5 tons. And this is provided that the useful volume of an average dump truck is 12 m3.

So, figuring out how to convert cubic meters to tonnage turned out to be not so difficult. The main thing is to know a few parameters.

Cubic meters per ton

Before starting any construction, it is necessary to accurately calculate how much material is needed for certain structures. This is a very important stage, therefore, in construction companies, entire departments are created to carry out such calculations and budgeting.

But you can independently carry out such calculations if you yourself decided to start building your own house. In order that you do not have excess material or, on the contrary, do not have enough of it, it is necessary to correctly calculate the weight of crushed stone in 1 m3 or in a ton, or to convert m3 to tons.

To find this value, they usually use the services of special laboratories. To determine the bulk density of crushed stone, special tests are carried out with the help of which the density of the material is determined. How is it possible to convert a ton of rubble into a cube?

To convert a ton of crushed stone to cubic meters, the weight of the material should be divided by the bulk density. Let's look at an example. Let's say you ordered a dump truck with a lifting capacity of 20 tons. So, the weight of crushed stone is 20,000 kg, and its bulk density is 1,500 kg / m3.

After carrying out the calculations, we get as a result a volume that is equal to 13.3 cubic meters. Thus, a dump truck with a carrying capacity of 20 tons is capable of transporting 13.3 cubic meters of product.

Recall that the density of crushed stone of 1500 kg / m3 is not constant. It depends on the value of the fractions and varies from 1400 to 1600 kg / m3.

For a more convenient calculation, you can use the table, which shows the weight of crushed stone 1 m3, taking into account the value of the fraction.

Is it possible to carry out an accurate calculation of sand on a calculator

Of course, it is difficult to calculate the exact volume of sand in a ton on a calculator, since for this you need to know the above characteristics. But in order to know these numbers, it is necessary to conduct laboratory studies, for this you need to have exact numbers, and not those that we see in the tables (rounded).

To facilitate the task for the builders, it was decided to take approximate figures for the calculation:

1. humidity - 7%;
2. density - 1600 kg / m3.

Of course, there will be a small error in the calculation, but it is more cost-effective than the decision to conduct laboratory research. The volume of sand is calculated approximately. But in order to get clearer data, it is worth taking 1-3 cubic meters more.

This is necessary to take into account the losses that arise during transportation - it is compacted, dissipated.

Calculation rules

Conversion from cubic meters to kilograms, and vice versa, is made based on accurate data on all of the above factors. Such information can only be obtained through laboratory work. The procedure is expensive, the quantities require constant monitoring of measurements. Therefore, it was decided not to weigh, but to measure the mixture in cubic meters.

Conversion by weight

The mass of the cube is calculated by the formula: m = V * p. This is the product of volume and density. The volume is known, it is 1 m3. The density is found in the look-up tables.For example, let's calculate the specific gravity of the building molding material 0.2 m3, the particles of which, according to GOST 2138 - 91, have a compaction of 1710 kg: m = 0.2 * 1710 = 342 kg / m3.

The weight of commonly used types of building sand in 1 m3 is summarized in the table:

This is a reference data that takes into account the natural moisture content of 6 - 7% of the total mass. When calculating the required amount, in order to find out how much 1 cube of sand contains a kg, it is advisable to use the coefficients 1.1 - 1.27. For example, if you need 5 cubic meters, then it is worth purchasing 5.5 - 6.4 cubic meters.

Machine capacity

How many cubes in a KAMAZ dump truck or any other car are calculated based on the carrying capacity of the truck. The equipment has a different body capacity - from 6 to 50 tons. Calculations again run into the knowledge of the weight of the material. A few more examples, now based on average density:

• 4 * 1600 = 6400;
• 6 * 1600 = 9600;
• 8 * 1600 = 12800.

The figures obtained are the weight of bulk raw materials for 4, 6 and 8 m3, respectively, presented in kilograms. The result is divided by 1000 to get the tonnage and is determined with the capacity of the machine. The minimum capacity of the ZIL is 6 tons, which is no longer suitable for any of the presented volumes. We need machines with a lifting capacity of 8 tons.

Focus on density

It is important to take this indicator into account when choosing a specific type of sand mixture to determine the means of its transportation. A ten-ton car with a body volume of 6 cubic meters is capable of transporting 8.3 m3 of sand with a density of 1650 kg: 6 * 1650 = 9.9

But if the compaction of particles exceeds this level, the technique will not cope: 6 * 1800 = 10.8 tons.

How many cubic meters are in a ton is an important issue when loading a car. It must be understood that the value always corresponds to the specific gravity. The relationship of these parameters gives approximate figures for the capacity of sand in various loaders. Some vehicles have severe limitations on the volume of the body, which prevents them from being used to their full potential. With a moisture content of 5 - 7% and a density of 1600 m3, it is possible to transport:

• in ten-ton machines - up to 8.5 cubic meters of the mixture;
• 17 t - 10 m3;
• 31 tons - 20 cubic meters;
• 50 t - 25 m3.

A similar calculation can be made for any container. For example, in a bucket with a volume of 10 liters with a standard compaction rate and moisture content, you get 0.008 m3 or 8 kg. Accordingly, a 50 kg bag of sand will weigh 31.2 kg. Such calculations should be applied directly when mixing concrete in order to obtain a high-quality structure.

Varieties

There are many varieties of sand. Each of them has found its application in everyday life and construction. Below are the most common types of sand.

River

Outwardly, it is a free-flowing material, not ore.

Its plus is that it does not contain: clay, dust, salt, pebbles, and so on.

River

This type of sand is mined in two ways - by equator draglines and hydro-mechanized method. River sand can be easily distinguished from others by its external data. It can be white, yellow, or gray. GOST 8736 sand is used in everyday life and construction.

If we talk about construction, then it is used in the manufacture of reinforced concrete structures, as well as in the manufacture of paving slabs, road slabs, and so on. Characteristics: density - 1.5 kg / cbm, sand moisture - 4%, specific gravity - 2.65 g / cc;

Quartz

Quartz sand is a special free-flowing material that consists of small granules with a diameter of 0.05-3 mm.

Quartz

It is the impurities that give the sand a certain shade, if we talk about pure quartz sand, then it is milky white. It is used in many areas: sandblasting, for the manufacture of glass, for the manufacture of concrete and other materials.

Due to its good characteristics, such sand can be painted in any color, which helps to create decorative plaster. Characteristics: moisture less than 10%, clay content 1%;

Career

In essence, quarry sand is ore, loose material, granular. It contains particles ranging in size from 0.7-5 mm. There are 3 main ways to get this type of sand: sifting, washing, open method.

Career

This type of sand is used in all foundation works and road construction works. Sand characteristics: modulus 0.7-5 mm, impurity content 10%;

Nautical

It is a non-metallic bulk material. It is easy to find it on the seabed.

Nautical

It has a wide range of applications, from a banal construction site to the production of various dry mixes. But unfortunately, this type of sand is quite rare, since it is not always possible and convenient to extract it;

Artificial

Since the above types of sand are natural (except for quartz), artificial sand can also be noted.

Artificial

Before choosing the right sand, you need to know all its characteristics, and calculate the correct volume of sand using rules and formulas. The main characteristics of sand include:

• sizes, size index;
• radioactivity;
• specific gravity;
• a direct indicator of the bulk volume;
• the amount of impurities in the sand;
• filtration coefficient;
• compaction factor;
• density.

Varieties of natural sand

Natural and artificial sand is increasingly found on store shelves today.

River

The one that is mined from the river bottom. It stands out for its cleanliness indicators. May have a yellowish or grayish tint.

River

Particle dimensions reach 0.3 to 0.5 mm. It is used at the stage of mixing mixtures for construction, as well as mortars, during the installation of drains. It is considered the most used and popular type.

Career (dusty)

Dusty is extracted in the classical way. Its shade is brownish or yellowish. The material contains dusty impurities and small stones.

Career

In a purified and classical form, quarry sand is used for a thick lime mortar and a complex of construction work related to the exterior and interior decoration of buildings; on its basis, a cement screed is created.

Extracted from the seabed and characterized by improved quality.

Nautical

Artificial

Artificial is made from mountain material.

As a result, it is possible to obtain a homogeneous material, in the composition of which there are no chemical elements that have passed into the composition of the alloy during their production, but the particles have an acute-angled shape.

Artificial

It is used to create a cement-sand mixture with increased density. The most common types are:

based on quartz. It is mined by crushing and sieving a snow-white mineral. Quartz sand is used for a complex of construction work related to external and internal decoration;

Quartz

based on expanded clay. It is mined by crushing expanded clay clastic rock in the form of small stones and inorganic materials. It is also possible to burn small residual clay impurities. It is used at the stage of mixing concrete, for filling the foundation pit, in order to level the surface;

Expanded clay

based on slags. The crushing of this material into small particles is carried out by their instant cooling with H2O. This material is characterized by a variety of grain sizes: from 0.6 to 10 mm. Used when mixing mortar for construction.

Slag

According to the content of minerals, several groups are distinguished, which include one or more minerals.
