Comparative Research on Exploitation Frost Resistance of Ceramics and Concrete

Abstract

The aim of the work is to compare the influence of physical and structural parameters on the exploitation frost resistance for ceramics and concrete of walls and partitions. The physical and structural parameters of small effective porosity (We ≤ 26 %) ceramics and concrete are determined: density (ρ), reserve of porous volume (Rp), capillary rate of mass flow (G), effective porosity (We) and exploitation frost resistance (FE). Possibilities to predict the exploitation frost resistance of ceramics and concrete according to the indicated parameters are analysed. It is established that the exploitation frost resistance of small effective porosity (We ≤ 26 %) ceramics and concrete may be predicted applying very similar empirical equations obtained. They justify analogous valid laws of exploitation factors affect for ceramics and concrete during exploitation.
