Abstract: After the construction solid waste is broken, it is directly used as recycled aggregate, which often has the disadvantages of large porosity, high water absorption and low strength, resulting in low strength and poor durability of the recycled concrete prepared by it. Therefore, the effective use of recycled aggregate in concrete is limited. For this reason, researchers have carried out systematic research on the modification of recycled aggregate in order to realize the reuse of resources. The research shows that the strengthening methods of recycled aggregate can be divided into physical methods, chemical methods and microbial methods to make up for the defects of recycled aggregate. In this paper, the concrete content of recycled aggregate strengthening method is reviewed, which provides some theoretical support for the treatment of construction waste and its utilization as recycled aggregate.
