The method of determining the amount of moisture evaporating from concrete in a chamber during hardening with the use of only heat of hydration of cement has been developed and worked out. Experiments were carried out using samples of (0.1 x 0.1 x 0.1 m) of heavy concrete. It was established that in the studied conditions, the presence of processes of mass exchange between the concrete surface and the space of the chamber during the solidification does not affect the water absorption of concrete and the strength of concrete at compression at an early age. It is recommended not to carry out waterproofing of heavy concrete products during their heat treatment in conditions similar to those under study.
