Abstract
The possibility of using fine recycled concrete aggregate as a substitute for natural sand are relatively limited. In order to promote it for engineering application, this paper reports the effect of elevated temperatures from room temperature to 600oC on the compressive behavior of mortars containing recycled fine concrete aggregate was investigated. It is found that no obvious relation between the color change and the recycled mortars replacement percentage.And the mass loss of recycled mortars is larger than that of normal mortars.The compressive strength of recycled mortars declines significantly as the temperature rises. The elastic modulus of recycled mortars decreased with the increase in temperature, and the decrease is much quicker than the decrease in compressive strength.
