Abstract
Concrete hardening conditions are the main factors affecting the achievement of operational concrete structures properties. Optimal conditions provide conditions for the cement clinker hydration, rate determine of strength gain, reduce the probability of formation shrinkage cracks, and retain a sufficient amount of moisture in the concrete body to increase cracking resistance. In practice, on many construction sites, the ratio of maintenance to concrete hardening is negative. There is no temperature and humidity regime for concrete hardening. Сement clinker hydration can only occur in wet conditions and if there is water in the capillaries of cement stone, it is necessary to create high humidity for concrete hardening to prevent moisture loss due to evaporation. The optimal heat-moist concrete hardening mode helps to reduce the porosity of hydrated cement stone, reduces the pores size and their shape, and increases of concrete microstructure density
