Study on Fire Resistance of Cement

Abstract:

This work aims to study the effect of sintering temperatures on the compressive strength and weight of net cement. The compressive strength and quality variety of cement which undergo different sintering temperatures (400°C, 600°C, 800°C, 900°C) and sintered at different times (1h, 2h) are studied through experiments and theoretical analysis. By using XRD explore the inner of sample chemical composition and further obtain the mechanism about sample of weight loss and strength loss. The main internal components of cement are Ca (OH)₂, C-S-H, Ca₂SiO₃ and CaCO₃ at room temperature. When the temperature was up to 400°C, The internal structure of cement started to be destroyed due to its hydration products C-S-H, Ca (OH)₂ and CaCO₃ began to decompose slowly.
