Method for determining the degree of influence of the heating temperature on the strength set of concrete based on isotherms

Abstract

The article presents the development of an alternative approach to determining the degree of influence of the curing temperature on the concrete strength gain, based on the construction of isotherms. Based on the test results, isotherms were plotted, representing the graphs of strength gain for each of the temperature regimes. Visual and numerical comparison of the concrete strength values obtained from isotherms gave an understanding of the degree of influence of sample heating on strength development.
