INVESTIGATION OF THE DAMPED CREEP OF CONCRETE IN BENDING USING  SPECIAL EQUIPMENT AND TAKING INTO ACCOUNT THE INFLUENCE OF POLARITY OF A SURFACE-ACTIVE SUBSTANCE

It was show that the creep deformation of pumice concrete with an aggregate saturated with 0.5% CaCl2 solution is an essentially more intensive process than the creep deformation of pumice concrete prepared with a water-saturated aggregate. Hence we conclude that the higher the SAS polarity, the higher its wedging-out action which intensifies the development of creep deformation.
