摘要：

In the paper the influence of a compression load on sulphate corrosion rate of mortar is studied. It is shown that the applied compression load up to level of 60% from compression strength value of the given mortar significantly slows down this rate. This inhibition effect by decrease of content of bound SO3 and destructive phases, as ettringite and gypsum in attacked material is connected. A relatively high - quality pore structure of attacked mortar was the further result of mentioned inhibition effect. The reasons of the effect are analysed and discussed and the quantitative relationships between studied corrosion rate factors are given.
