Applying the dimensional method for valuation of the strength loss of cement compositions exposed to elevated temperatures

Abstract

The paper presents the basis of the analytical model for calcu-lating the loss of strength in ce-ment compositions exposed to elevated temperatures. This model is to replace the classical method of calculating the fire resistance of the loss of load-bearing capacity. The experimental data were taken as initial indicators. Based on the implemented calculations it would become possible to predict the occurrence of ultimate state by loss strength and the reliability of practical indicators obtained by means of full-scale tests
