Description

The invention relates to compositions of betan mixtures, cores additives, improving those. Or other properties of concrete.

A concrete mixture is known that switches off the mineral to a moving, sunflower, water and polymer additive.

The purpose of the invention. is increasing ductility and reducing cement consumption.

This is achieved by the fact that the concrete mixture contains as an additive the product of copolycondensation of ortho-aminobenzoic acid with esterphenols in an amount of 0.01-0.015% of the binder weight.

The presence of IB of the concrete mix of this additive slows down the hardening of the concrete, without requiring a change in the adopted penetration mode.

The proposed additive is obtained by copolycondensation of ortho-aminobenzoic acid with sterol phenols L 60-70 ° C for 2 hours.

The mixture on (Suggested nlififvkator) (prepared as follows.

50% -; water emulsion additives rabevav, poured with water to a density of 1.01 and injected into the concrete mix, together with the mixing water at the rate of 0.01-0.015%, on a dry matter of the weight of cement.

After heat treatment of the concrete product with the additive, it has a good presentation and uniform structure.

The use of an additive reduces the cement consumption per 1 m of concrete to 10%.

The use of an additive permits the production of smooth concrete mixes without slowing down the hardening of the concrete, as in the early stages of hardening.

Subject invention

Concrete mix, including blend. Mineral to grit, aggregate, water and polymer additive, characterized in that, with a view to. To reduce plasticity and reduce cement consumption, it contains, as an additive, the product of sonolycondensation of ortho-aminobenzoic acid with ether phenols in an amount of 0.01-0.015% of the weight of the binder.
