Description

(54) CONCRETE MIXTURE

one

The invention relates to building anticorrosive materials and can be used for the manufacture of structures and the erection of structures used in aggressive environments.

The known concrete mixture, including Portland cement, coarse and fine aggregates, water, and polymer additives. Low molecular weight polyethylene is used as an additive.

The closest to the invention according to the technical essence: and and the achieved result is a concrete mix containing portland cement, sodium methylsiliconate, aerosil, sand, crushed stone, granite and water 2.

Known concrete mixtures have insufficient strength properties. For example, there is a significant difference between compressive strength and tensile strength, which in large-sized reinforcement structures leads to the formation of cracks with changes in environmental temperatures.

The aim of the invention is to increase the efficiency and the ability to stretch concrete.

 is achieved by the fact that a concrete mixture, including Portland cement, sodium methylsiliconate, aerosil, sand, crushed granite and water, additionally contains aluminum vinyl chloride waste production of polyvinyl chloride in the following ratio of components, weight,

The concrete mix is prepared by the ladies.

Coarse and fine aggregates are mixed. Portland cement, previously mixed with an aluminum chloride powder, is introduced into the premixed mixture. Next, water was added with sodium introduced into methylsiliconate and aerosil. The mixture is stirred for 2-3 minutes.

Below are the approximate compositions of the proposed concrete mix, wt.%:

Land cement, Methylsiliconate sodium, Aerosil, sand, crushed granite and water, characterized in that, in order to increase the deformability and tensile strength of concrete, it additionally contains aluminum vinyl chloride waste production of polyvinyl chloride in the following ratio of components, wt.%:

The test results of the proposed composition of the concrete mix are presented in the table.

The fine mixture of aluminum vinyl chloride is evenly distributed in the mass of concrete. When hardening, it creates a polymer layer, increasing the adhesion of the filler grains to the cement stone. This increases the tensile strength and deformability of the concrete.

Thus, it becomes possible to increase the dimensions of a structure made of chemically resistant concrete, to apply more efficient reinforcement and to eliminate the formation of cracks in the body of reinforced concrete.
