Description

one

The invention relates to the composition of mortars and concretes for minerals in living, containing additives.

Construction solutions containing cement, sand, water, and as a additive, low-calcium calcium hydrosilicates are known.

The purpose of the invention is the improvement of the flexural strength of mortar.

This is achieved by the fact that the solution contains, as an additive, filamentous calcium hydrosilicates with a diameter of 0.1-10 microns, a length of 1.0-500 microns in an amount of 0.05-5.5% by weight of cement.

Calcium hydrosilicates are used as a reinforcing agent.

The described mortar contains 1 weight. h. Portland cement, 3 wt. including quartz sand, water with a water-cement ratio of 0.45 and 0.05-5.5% of the weight of cement of calcium hydrosilicate with a diameter of 0.1-1.0 microns and a length of 1.0-500 microns, as a reinforcing additive. The compressive strength of the material is 522, with a bend of 174 kg / cm. The proposed mortar can be used in concrete and reinforced concrete products with reduced cement consumption while reducing the hardening time.

Subject invention

A mortar comprising Portland cement, sand, water and an additive, characterized in that, in order to increase the ultimate strength of the products obtained in bending, it contains as an additive filamentary calcium hydrosilicates with a diameter of 0.1 - 10 microns, 1.0-500 microns in length , in the amount of 0.05-5.5% by weight of cement.
