VARIATION IN THE MECHANICAL PROPERTIES AND TEMPERATURE OF MODIFIED REACTIVE POWDER CONCRETE

This research presents an experimental investigation to study the effect of elevated temperatures on mechanical properties of conventional and modified reactive powder concrete. The mechanical properties which investigated in this study are compressive strength, tensile strength, modulus of rupture and modulus of elasticity. Twelve tested specimens were casted for each property; these specimens were tested with different exposed temperatures (28 OC, 60 OC, 100 OC and 150 OC). The results indicate the effect of increasing the elevated temperatures have a vital role to decrease the compressive strength, tensile strength, modulus of rupture and modulus of elasticity of tested specimens
