Depending on their brand, the mixtureSand-cement can be used for various types of work. It is widely used in the repair work of the foundation, as well as for certain types of finishes. The choice of material should be based on many factors. The more carefully it is implemented, the more durable the surface will be.
The composition includes cement and sand, whichdiluted in a certain proportion of water and used for pouring foundations. In addition to the main constituent elements, mineral additives can be used in the mixture, which can change some properties of the mixture, for example, its strength or ductility.
Adding certain elements to a significantdegree can affect the characteristics of the sand-cement mixture. Observance of the correct proportions is necessary to achieve maximum strength of concrete. If the mixture is excessively diluted, then the concrete will crack later, which will significantly worsen its performance characteristics, and will greatly shorten the period of full-fledged use.
With the help of such a mixture, it is possible to brick the walls, fill the foundation or repair cracks of various surfaces.
This sand-cement mixture is used forplastering of walls. It is the most widely used building material. Portland cement is used for its production. It can be of the brand PC 400 D20 or PTS500 D0 (to which fractionally sand is added in dry form). After diluting such a mixture with water it is necessary to let it stand for about five minutes. This time will be enough to achieve a concrete solution of maximum strength.
The surface that will be exposedprocessing must first be primed in several layers. This action will help increase the strength of bonding the solution to the surface and, accordingly, significantly extend the service life.
Use of the cement mixture M150 can be used for:
When working with this material, special attention should be paid to safety. It is important to use special tools and working gloves that will prevent the solution from getting on the skin.
This figure indicates that the sand-cement mixtureUsed for masonry work. It has increased strength, and is used for finishing various surfaces. When working with a mixture, you must follow a certain order of work:
The total strength of the surface is ensured approximately 28 days after the completion of the work.
The cement mixture M300 is a concrete used for the construction of surfaces, which must have the highest strength. This brand is used for the following works:
Sand concrete can be used for levelingfoundation surfaces. This mixture can only be used in rooms that are not exposed to high humidity and high mechanical loads.
When diluting the mixture, it is necessary to strictly observethe dosage indicated on the package. Adding the mixture is carried out in cold water with a temperature of no more than 20 degrees. The dry mixture, which is injected, must be constantly mixed and injected evenly, if lumps are formed, the quality of the mixture will decrease significantly.
Then it is necessary to leave the prepared solution for five minutes so that it is infused. It is necessary to use the mixture within two hours, if the solution freezes - it needs to be mixed.
Sand-cement mixture for paving slabs is prepared according to the same principle. It gives an opportunity to conduct qualitatively any masonry work.
If we consider the consumption of sand-cement mixturesquare meter, then at a layer thickness of one centimeter it will be necessary to use approximately 22 kilograms of the dry mixture, which in this ratio should be diluted with water.
The calculation per cubic meter is only used in large-scale construction enterprises. In this case, for 1 m3 it will take about 650 kilograms.
To calculate the amount of material,it is important to take into account the thickness of the concrete layer. It often varies within 1-1.5 cm. With this thickness, you need to use 25 kilograms of the mixture.
Sand-cement mixture for laying canvary significantly in the price category. It depends on its brand, weight and used additives, affecting the characteristics of the material. In average, we can call such prices: the price of the mixture starts from 64 rubles. for a bag weighing 25 kg (varies depending on the country of origin, ready - 2300 rubles per 1 cubic meter.
For construction and finishing work, alwaysit is necessary to use a suitable material. A mixture of cement and cement will help cope with many defects, create a uniform floor or wall covering, as well as neutralize cracks in surfaces.
The choice of material should be based onnecessary functionality and type of work for which the mixture will be used. The more carefully the choice is made, the better and more durable the surface will be.
