Experiments was conducted to study the influence of temperature on the performance of rubberized concrete. The obtained results show that under vacuum condition after exposure to 250℃ the morphology of rubberized concrete does not change significantly, while its strength rises remarkedly and the increase rate of the strength for the rubberized concrete using 149μm (100 mesh) rubber powder is higher than that for using 4000μm (5 mesh) rubber powder. After exposure to 250, 500, 800℃ in air, the compressive strength of the rubberized concrete using 149μm rubber powder reduces more than that for using 4000μm one.
