The Influence of Changes in the Specific Heat Capacity and Thermal Conductivity of Concrete on the Accuracy of the Development of Mathematical Models of Its Hardening in Thermal Technology Installations

Based on the analysis of literary sources and our own research, the limits of changes in the specific heat capacity and thermal conductivity of concrete during their heat treatment in thermal technology installations have been determined. The influence of the temperature maintained during the heat treatment and the degree of hydration achieved as a result of heating on the values of these thermophysical parameters has been established. The conclusion is made about the determining effect of changes in the thermal conductivity of concrete during its heat treatment (compared with the specific heat capacity) on the results of analytical and numerical calculations of heat treatment modes.
