Experimental Research on the Preparation of Heat-Resistant Concrete Using Normal Portland Cement

Abstract:

Based on the heat-resistant mechanism, the orthogonal experimental method and the requirements for physical-mechanical performances of heat-resistant concrete, one mixing process project was taken as the target for analysis on the mixture ratio design of heat-resistant concrete. The conventional raw materials such as normal Portland cement, common crushed aggregates, fly ash and concrete admixture were adopted to manufacture the C30 heat-resistant concrete which gets the limit heat-resistant temperature of 500°C subsequently. And the influencing factors on the strength of heat-resistant concrete were also studied in this paper. Experimental results show that the mixture ratio design of heat-resistant concrete in this paper is reasonable. The engineering application results also show it is financially viable that adopting the normal Portland cement to manufacture the heat-resistant concrete with limit heat-resistant temperature of 500°C.
