description: Heat generation during cement hardening is important from a practical point of view. Due to the low thermal conductivity of concrete, loss of heat in massive structures is slow. Unlike thin-walled structures, only surface layers are cooled in massive ones, while there is substantial warming and expansion of the center of the structure. As a result, tensile stresses occur in the surface layers of the concrete block, resulting in temperature cracks. Evaluation of concrete thermal stress condition of massive structures during construction period is one of important tasks to ensure operational reliability and structural durabilities. 
This masterâs thesis deals with the problem of thermal cracking resistance of the massive reinforced concrete foundation slab during the construction period and covers the theoretical bases of the thermal stress state of concrete. In addition, the method of calculation of the mode of peripheral electric heating of the structure has been developed.
