IMPROVING THE PROPERTIES OF CEMENT COMPOSITES BY CURING THEM USING AGGRESSIVE INFLUENCES
Main Article Content
Abstract
It is noted that the curing of cement composites is impossible without effects and is a reaction to them. In this case, the forces of the resulting resistance, according to the laws of thermodynamics, are aimed at weakening the impact. Experimental prerequisites and arguments are given that by choosing the time, intensity and duration of aggressive action on cement composites during their curing, it is possible to obtain more impact-resistant or ordered and durable structures of the material. The creation of conditions for the hardening of cement composites using liquid aggressive media leads to the formation of a dense inert layer on their surface, more adapted to the effects of this type. Using temperature and humidity influences, freezing and thawing, and loads, more durable composites were obtained. Thus, the curing of cement composites using time- and intensity-determined harsh temperature and humidity conditions, freezing and thawing, aggressive liquids, and loads makes it possible to obtain more durable or resistant structures of the material to specific destructive factors.
