Extended Abstract: The aim of the research was to determine how sulfur-containing compound impregnation influences on concrete compressive strength and the impact resistance of concrete tiles. The results of these studies indicate that impregnation of vibropressed concrete paving tiles and concrete samples of dif-ferent strength classes with aqueous solutions

based on calcium polysulfide leads to a significant increase of compressive strength and impact resistance. These data show that the strength of the products can be controlled by varying duration and frequency of the impregnation and by using pre-vacuum method. Impregnation with a solution of calcium polysulfide density of 1,23 g/cm³ can be recommended to increase strength of concrete products that are exposed to intense hydration and mechanical stress.

Key words: concrete, sulfur, compressive strength, impregnation, hydrophobization, nanoparticles, durability, polysulphide.
