This fine -grained concrete is a novelty in the market for dry building mixtures. Its base is Portland cement, large sand and plasticizers that provide plastic properties of the mixture. These chemical additives, among other things, improve the properties of sand concrete, making it frost -resistant and waterproof. The diameter of the grains of sand in the mixture is in the range of 3-6 mm, which gives greater strength to the material. The main property of sand concrete is the complete absence of shrinkage processes. It hardens very quickly, so suitable for use even at fairly low temperatures. It has proven himself quite well when screeding floors, laying bricks, as well as with fastening structures made of reinforced concrete.
