frost resistance.

Покращення експлуатаційних властивостей керамічної цегли поверхневим модифікуванням поверхні

In the article there are substantiated and determine the optimal composition of protective covering by the mathematical planning method with taking into account the influence of protective covering on water absorption, adhesive strength and frost resistance. It is constituted technologic regime of marking and hardening protective covering on the ceramic matrix surface. It is determined the depth of protective covering penetration and its role in the adhesive contact formation during hardening process and its dependence from ceramic matrix structure.
