Abstract

In order to study the difference of recycled aggregate concrete and ordinary concrete in basic mechanical properties. The artificial broken way is applied to abandoned concrete, recycled aggregate and cement slurry soaking are mixed, according to ordinary concrete mix design method of configuration of recycled concrete, concrete with recycled aggregate replacement rate is 0, 20%, 40%, 60%, 80% is tested. The results show that the compressible strength and elastic modulus of recycled concrete decrease, but the physical properties of recycled concrete can be improved, and the apparent density of recycled concrete can be reduced. When the replacement rate of recycled aggregate is not more than 40%, the high compressible strength can be obtained, and recycled aggregate made of construction waste can be used to replace the natural aggregate to configure recycled aggregate concrete.
