Description:
The study attempts to demonstrate that it is possible to apply classical equations of chemical reactions for assessing the strength of concrete, cured in winter. This assumption differs from the existing classical theories of strength development in concrete, based on physical approaches. The graphs of the known normal temperature dependences of the chemical reaction rate and the increase in substance concentration in time allowed us to confirm the possibility for further research of strength development in concrete from the standpoint of chemical theories. For these purposes, the Van’t Hoff and Arrhenius equations were considered. To compare the results of theoretical studies with real constructions, we conducted an extensive experiment that involved a testing machine and a temperature chamber to assess the actual development of concrete strength in time at different temperatures (5, 20, 40, and 60°C). The temperature graphs of hardening of B40 concrete were plotted. Both equat...
