WEAR RESISTANCE OF POLYMER-IMPREGNATED MORTARS AND CONCRETE

The wear resistance of mortar and concrete samples untreated and impregnated with solutions of epoxide resin was tested. The compressive strength has a decisive influence on the abrasion of untreated mortar and concrete samples. The idealized diameter area of the maximal grain of the gravel in the sample has less influence on it. The wear resistance of impregnated samples with low compressive strength markedly increases. The hardener used influences the polymerization rate of the activated resin in the structure of samples, with time, and their abrasion is influenced also in this way.
