Abstract

The paper deals with technologies of concrete surface improvement. Concrete surface is important because of its hardness, durability and other problems. Besides, it is necessary to protect it from aggressive environment. The purpose of the article is to introduce a few techniques of silica sol use in order to change concrete surface properties. The absorption, irrigation and watering processes were applied as the techniques. Both silica sol and its mixes with solutions contained Ca(II) were used as the substances. The experimental methods were realized during the study. The experiment results have shown that hardness of heavy concrete and foam concrete surface was increased up to 40–50% and the level of soil strengthening was 0.2 MPa. It means that if silica sol and solutions containing Ca(II) are used the soil strength is increased more than 40–50%.
