Abstract:
In this article, a physical and mathematical model of the unsteady process of heat and mass transfer in a flat reinforced concrete structure during its heat treatment by solar energy is proposed and considered. Monolithic concreting in the conditions of a construction site is currently widespread in the construction industry. The subject of the article is to consider the issues of heat treatment of concrete and acceleration of its hardening processes using solar energy. Analytical expressions have been obtained that simulate the process at any stage of it, which makes it possible to actively intervene and adjust the external parameters of the environment to create rational and comfortable conditions for concrete strength growth.
