PORE STRUCTURE, MODULUS OF ELASTICITY AND MEASUREMENT OF DEFORMATIONS IN A COLD STATE WITH A VIEW TO DETERMINING THE RESISTANCE OF CONSTRUCTION MATERIALS TO FROST

STRUCTURE DES PORES, MODULE D'ELASTICITE ET DILATOMETRIE AU FROID EN VUE DE LA DETERMINATION DE LA RESISTANCE AU FROID DES MATERIAUX DE CONSTRUCTION

Based on the knowledge of the frost behavior of water in capillary systems and the filling process of capillaries with water, it is possible to accept the fact that only pores of average size can be held responsible for the damage to materials caused by frost. Thus if a satisfactory understanding of the frost resistance of a material is to be obtained, analyses of pore distribution must be conducted and supplemented with miscroscopic studies of the shape of the pores. On their own, the mechanical properties of a material give little information on the resistance of a material to frost, but it is possible to assess this resistance by studying the variations in the modulus of elasticity, especially in the case of repeated stresses caused by frost.
