Abstract: The types and mechanisms of shrinkage deformation of cement concrete and the most effective ways to combat shrinkage crack formation have been considered. It has been found out that in natural conditions reinforcement, a rigid coupling with the base of the pavement, the interaction with other constructions in humid cement concrete shrinkage gives rise to internal stresses exceed the tensile strength of the concrete, which lead to cracking. The presence of cracks leads to a decrease in the durability of concrete products because it is a chemical corrosion of cement concrete and reinforcement steel. Shrinkage-compensated concrete that contains complex additives, reducing shrinkage, expanding cements, synthetic fibers has been suggested.

Keywords: shrinkage, plastic, autogenic, humid, heat, carbonization, cracking, polymers, domestic care, water-saturated filler.
