INFLUENCE OF AGGRESSIVE ENVIROMENT ON DURABILITY OF PORTLAND CEMENT BASED DRY BUILDING MIXTURES

V. Tokarchuk, Y. Kovalenko

Abstract


The corrosion resistance of dry building mixtures on the basis of Portland cement of general construction purpose was considered. The choice of types of dry building mixtures for research was substantiated. Their physical and mechanical properties and corrosion resistance in the conditions of contact with various aggressive environments have been studied. It has been established that the corrosion resistance of dry building mixtures depends not only on the properties of the original cement, but also on the composition of the mixtures themselves. Significant impact on the stability index has the appearance of an aggressive solution. An increased corrosion resistance of the mixture which contains a polymeric component in its composition, had been noted.

Key words: dry building mixtures, portland cement, stucco, tile adhesive, corrosion resistance
