According to the prototype, the concrete mixture was prepared by blending the resin and hardener mixtures in the gates, and then they were mixed with dry gesio celeit and fillers.

Conditions of hardening of molded products are thermal moisture.

The resulting figurative from the proposed and known concrete mixtures had the following indications of the properties given in table. 2
