CRITICAL DEGREE OF SATURATION - A TOOL FOR ESTIMATING THE RESISTANCE OF CONSTRUCTION MATERIALS TO FROST

DEGRE CRITIQUE DE SATURATION - UN OUTILPOUR L'ESTIMATION DE LA RESISTANCE AU GEL DES MATERIAUX DE CONSTRUCTION

The theoretical and experimental study of the effect of frost on porous and brittle construction materials showed the existence of critical degrees of saturation. The critical degree of saturation is a constant of the material which has a well defined value for a given type and quality of the material under study. It was shown that deteroriation occurred after frost if the actual degree of saturation exceeds the value of the critical degree of saturation. It is possible to select a material as a function of its resistance to frost by comparing, for different materials, the critical degree of saturation and the degree of saturation actually reached under given conditions. The use of the critical degree of saturation helps to eliminate the lack of correlation existing in some cases between results obtained during frost tests and results obtained during utilization of the material. /TRRL/
