Description

(54) CONCRETE MIXTURE

one

The invention relates to compositions of concrete mixtures containing target additives.

A concrete mixture is known that includes a mineral in a moving, aggregate, water and additive. A mixture of sodium sulfate and potassium chloride is used as an additive.

Closest to the proposed technical essence and the achieved result is a concrete mix, including cement, sand, crushed stone, water and an organic additive. As an additive, a product from the high degree of pyrolysis of gasoline is used in an amount of 0.01-0.2% of the total mass 2.

However, the known concrete mixes do not allow to obtain concrete with a sufficiently high water resistance and corrosion resistance.

The purpose of the invention is to increase water resistance and corrosion resistance.

The goal is achieved by the fact that a concrete mixture, including cement, sand, crushed stone, water and an organic additive, contains as an organic additive waste from the production of dimethyl dioxane and synthetic isoprene rubber in the following ratio of components, May / o:

Cement

11.2-13.2 Sand 18.4-20.3 Crushed stone 56.8-58.8

Claims (2)

Claim 1. A concrete mixture comprising cement, sand, crushed stone, water and an organic additive, characterized in that, in order to increase water resistance, corrosion resistance, it contains as an organic additive waste products of dimethyl dioxane and synthetic isoprene removal of rubber waste solution into concrete the mixture promotes the formation of evenly distributed closed pores. The proposed additive has a stabilizing effect and, moreover, is capable of internal hydrophobization of concrete. As a result of water repellency, the water resistance and corrosion resistance of concrete are increased. In tab. 1 and 2 shows the approximate compositions of the proposed concrete mix and the properties of the resulting concrete. Thus, the proposed concrete mix can significantly increase the water resistance of concrete, as well as improve its chemical resistance.
