Abstract:
This article proposes the usage of alternative energy instead of traditional, as safer, and environmentally friendly for the planet and all humankind in the manufacture of monolithic concrete and reinforced concrete products. Monolithic concreting in the conditions of the construction site is now widespread in the construction industry. The subject of the article is considered of the issues of heat treatment of concrete and acceleration of its hardening processes using solar energy. A brief review and classification of the most well-known and common energy sources used to harden acceleration of the concrete mix such as wind power, biofuels, solar energy, alternative hydropower is given. For consideration in the article offers the solar energy – the energy received from solar radiation. The sun as a source is an inexhaustible and affordable type of energy that supplies energy several times higher than traditional sources. In this regard, attention is paid to this field of alternative energy when using it in various spheres of the national economy, especially in the field of construction. Already existing methods of heat treatment of concrete with the help of solar technology are considered, the modern level of development of these methods is defined and further ways of their development are planned. As an example, a physical and mathematical model of a non-stationary heat transfer process in a flat reinforced concrete structure during its heat treatment using solar energy, considering the hydration of cement, is considered. Analytical expressions are obtained that allow us to model the process at any stage and actively intervene and adjust the external parameters to create rational and comfortable conditions for increasing the strength of concrete.
