Capillary permeability of concrete in aggressive dry hot climate

Abstract

The article presents the results of studies carried out to determine the capillary absorption (Wsuc) of a saline solution during evaporation and to establish a cyclic temperature regime. It has been established that for a reliable assessment of the capillary permeability of concrete in a dry hot climate, it is sufficient to subject the samples to 60 cycles of preliminary alternating heating and cooling, followed by testing in a climatic chamber for capillary absorption of a salt solution at a temperature of 40 °C and a relative humidity of 30%.
