Experimental Research on the Influence by Particle Shaping on Mechanical Performance of Recycled Aggregate Concrete

Mechanical properties of particle shaped recycled aggregate concrete,simply-crushed recycled aggregate concrete and natural aggregate concrete are studied in this paper. The experimental results show that mechanical properties of 100% particle shaped recycled aggregate concrete are lower than these of natural aggregate concrete. However,they are significantly higher than these of simply-crushed cycled aggregate concrete. Furthermore,mechanical properties of particle shaped recycled coarse aggregate concrete are notably higher than these of simply-crushed cycled aggregate concrete and 100% particle shaped recycled aggregate concrete. And they are slightly lower than these of natural aggregate concrete. Finally,the experimental results also provides reference for engineering practices.
