Abstract

Nowadays, more and more waste construction waste is abandoned in China, which makes the problem of environmental protection especially prominent. The reuse of waste concrete not only helps to solve the problem of landfill, but also contributes to sustainable development of resources. However, due to some defects of Recycled Aggregate(RA), such as large water absorption rate, many microcracks and old mortar on its surface, which lead to the utilization rate of recycled concrete is relatively low. The compressive and tensile properties of Recycled Concrete(RC) are lower than ordinary concrete. A large number of scholars have modified RC to improve the defects of recycled concrete. This paper reviews the modification of the recycled concrete aggregate and adding admixture modification. And it raises questions and reasonable opinions, which provide scientific basis and references for further research in the field of modified concrete.
