Abstract


Experimental study was carried out to investigate the mechanical properties of recycled aggregate concrete prepared with recycled aggregates obtained from local precast concrete industry and the findings of this study are presented in this paper. Five different concrete mixtures were prepared: one control mixture containing only natural aggregates and four mixtures of recycled aggregate concrete (RAC) containing natural and recycled aggregates at 25%, 50%, 75% and 100% replacement levels of natural aggregates. The results of mechanical tests such as compressive strength, modulus of elasticity, Load versus CMOD response, fracture energy in tension and compression are presented. The results indicate that at 25% replacement level, mechanical properties of RAC are almost similar to that of control concrete mix, however, mechanical properties of RAC are degraded when natural aggregates are replaced with recycled aggregates at replacement level greater than 25% and degradation is increased with the increase of replacement level
