Abstract

The crystallization process of soluble salts inside the natural and artificial porous materials partially immersed in
different saline solutions has been studied. This procedure is used to simulate the conditions of exposure to salt
weathering in which foundations and lower walls of building structures are within the zone of capillary rise of saline
ground water,
Crystallization pressures that can develop in the samples, which are a function of the pore size and salt solution
interfacial tension, have been calculated and are compared with experimental values of the materials tensile strength,
since both these parameters allow the prediction of porous materials behaviour against salt weathering.
