How much sand is available on 1 cube concrete. Components for creating a material under the ribbon base. Required components for lightweight material
Concrete is construction materialwhich has the form of a solid stone product obtained during the frozen of a concrete solution. In order for the erected construct from concrete able to withstand the necessary loads, you need to know the amount in 1m3 of all necessary components. To obtain a concrete solution, cement, water, sand and crushed stone are used.

Concrete thickness 100 square meters. Whatever the real manufacturer, he blends his solution and concrete. What you need to pay attention, we have collected for you. The solution consists of binder, sand and water. For concrete, the binder is cement, as additives, sand and gravel are used. In addition, the water is still used.What does Davidovich's geopolymer concrete look like, you can learn
To get a product of this type, it is necessary to carry out the selection of ingredients according to GOST 27006-86. Since the process of obtaining severe fine-grained concrete is conducted with different physical characteristics, then they have developed its own preparation technique. In mandatory, the obtained products are checked for strength.
How much water should be used, it is impossible to accurately predict. The prevailing outdoor temperature, air humidity and sand affect the need for water. By approximate estimate, one can expect that one pine water per kilogram of cement. For sand you must use a cleaned masonry or construction sand, not sandy sand. It contains salts that prevent complete curing.
The limestone is approved only for masonry a thickness of at least 24 cm, unloaded walls and a maximum of two floors. It is easier to process than cement mortar. However, it is less stable and penetrated for water. The mixing ratio is 3 pieces of sand and 1 part of the hydrated lime. Instead of hydrated lime, you can use lime or hydraulic lime. When using lime paste, the sand content increases to 4 parts of the space.
In order to prepare such a concrete, it is necessary to use sand. It is sent to a sieve with a cell of 2.5 mm, and then 1.2 mm. As a result, you get a large sand fraction. After you use a sieve with a cell of 0.315 mm, what will pass through it and will act as a placeholder.
The lime cement solution balances the qualities and disadvantages of other types of solution. Excess cement increases resistance, simplifies the lime to the processing. The mixing ratio is 2 parts of the lime or hydraulic lime hydrate, 1 parts of the cement and 8 parts of the sand.
Required components for lightweight material
Cement solutions are used for berths, storage and enhanced masonry. They are difficult to handle. However, compared with other types of solution, they are the most stable, waterproof and rapid. Of course, you also need water. The ratio of water to cement should be from one to two. For example, at 10 kg of cement, this corresponds to 5 kg or 5 liters of water.
To prepare a fine-grained concrete, you need to use the M400 or M500 grade cement, for them the characteristic bulk mass is 1100 kg / m3. In addition, sand and crushed stone is fine-grained. For the first material, the value under consideration will reach 1500 kg / m3, and for a rubble with a fraction of 0-5 mm, it will reach 1.41 tons / m3.

The cost of the obtained concrete will be high, because the process of high stamps, various additives and additives are used in the manufacturer. It is possible to reduce cost if you use better consumables. The process of cooking concrete can be performed by anyone, since nothing is difficult in it. However, there is another option - it is already a ready-made product.
Components and their bulk mass for the preparation of refractory concrete
In order to obtain a heat-resistant product, it is necessary to use various thin-fat impurities, liquid glass and portland cement. The heat-resistant concrete can be two types: normal or light, it all depends on the volume of volumetric mass. For lightweight material, the volume of the volumetric mass of 1500 kg / m3 is characteristic.

Thanks to the proportionable proportion for heavy item, it is possible to apply the product obtained when the foundation is arranged. The cost of fine-grained heavy mortar is a bit more expensive, since its composition has a greater amount of binding component.
Required components for lightweight material
To obtain durable foundation It is necessary to use crushed stone with large grains, as well as a very liquid concrete. Thanks to this, you can fill all empties. However, it is important before the fill it is important to correctly install the substrate using a low brand cement. According to the consistency, the finished material must resemble a wet soil.
The video describes the composition of light concrete:
The most common proportion is considered as follows: 1: 3: 6 - Cement: Sand: Crushed stone. However, the presented proportion is not universal, because the density of the product can change their meanings under the influence of various factors.
E can be seen table brand of concrete.
It is best to calculate the indicators based on technical directories. If the basis is considered the weight, then the weight is considered, then you need to dry sand and crushed stone so that the extra moisture does not violate the calculation. Such an approval is true for any other proportion of components. It is necessary to use only one container and, if necessary, make changes. Otherwise, the slightest error can lead to sad consequences.
Consider a bulk mass for each of the ingredients used:
- Cement M400 - 1100 kg / m3;
- Sand - 1440 kg / m3;
- Granite crushed stone - 1.41 t / m3.

If you need to make concrete for the construction belt Fundamentthen it is necessary to take care so that the cooked solution possessed necessary strength. In this case, it is very important to clearly observe the proportions and use only high-quality components. When choosing a cement, carefully read the date of its manufacture. Just cement can maintain its properties under normal storage conditions for 6 months from the date of its manufacture.

The video describes the composition of concrete for a ribbon foundation:
The sand should not contain in its composition of clay impurities, the poet will need to wet it. If the sand in the hands leaves dirty traces and sticks out, then it says about its low quality. The crushed stone used should be clean and have grain sizes 20-30 mm. For the preparation of concrete for a ribbon base, you can use the granite screening, but without dust.
Table 2 - concrete preparation proportions for belt base
As for another component - water, its quantity depends on the physical state of fillers, so it is not recommended to send it to the concrete mixer at once.
Consider a bulk mass for each component used:
- Cement M300 - 1100 kg / m3;
- Sand - 1680 kg / m3;
- Crushed stone - 1.35 t / m3.
The process of cooking concrete is very responsible events, because it is so important to accurately observe the entire proportion. But in the preparation of concrete of various types, it is necessary to take into account such a parameter as a bulk mass. If you can accurately have these data, you can prepare a high-quality concrete solution with the necessary strength characteristics and at the same time save your funds to buy an unnecessary material.
Many spend concrete work at home, pouring foundations or laying concrete floor. In this case, some builders are asked about the proportions of the mixing of raw materials (sand, crushed stone, cement, water). Often, for the preparation of special properties of concrete, for example, to obtain high frost resistance, various modifiers are introduced into the mixture.
Basically, concrete is prepared from cement, rubble and sand with the addition of water. The main weight in the composition of concrete occupies a large aggregate (crushed stone, gravel, granite, etc.). These materials are obtained by crushing rock breed on particles (fractions) different size. On average, one cube rubble weighs 1600 kilograms.
How many rubble needed to the cube (1 m 3) of concrete depends on its brand. Basically, the calculation of the strength (brand) of concrete is carried out on cement, it is it that affects this characteristic of the material after the final hardening. For example, for the brand of concrete M300, the following amount of raw components will need: 380 kg of cement M400 brand, 1100 kilograms of rubble, 220 liters of water and 705 kilograms of sand. As we see, the weight of large aggregate (rubble), much exceeds the weight of the other components. Exactly the same amount of rubble need for concrete M100 brand, the weight of other components concrete mix Such: Cement 210 kilograms, sand - 870 kilograms, water - 210 liters. The data of the brand of concrete is the most popular, let's look at how much the crushed stone for the cube (1 m 3) concrete of other brands.
To obtain concrete M50 brand, the following raw materials are needed: cement M400- 380 kg, Sand 645 kg, crushed stone 608 kg, the amount of water is standard for all types of concrete 220 l, the ratio of materials 1: 1.6: 1.7.
To get the M75 brand concrete, you need to take 175kg cement M400, sand takes 940 kg, rubble 1050 kg, the proportion of raw materials 1: 5.5: 6.
To obtain concrete brand M150 - 230 kg of cement M400, sand 850 kg and 1080 kg rubble. It turns out a ratio of 1: 3.6: 4.6.
Materials in the agitator are covered in the following sequence: first pour the required amount of water, then cement, and when it dissolves crushed stone, and at the end of the sand. The amount of raw material components on a stirrer can be found by separating the cube capacity (1000l) on its volume. Suppose the concrete mixer is designed for 200 liters of working mixture. To find out the amount of raw material components for the preparation of concrete M 150, we calculate the coefficient 1000/200 \u003d 5. Now we will learn the required amount of raw materials to one zam 230/5 \u003d 46 kg of cement, 850/5 \u003d 170 kg of sand, 1080/5 \u003d 216 kg of rubble, 220/5 \u003d 44 l of water.
