With the continuous increase in urbanization, the annual output of construction waste has consistently grown at a high speed. Based on extensive research and comparative analysis of relevant literature, this paper summarizes recent reinforcement methods for recycled concrete aggregate. The primary obstacle to utilizing construction waste resources is the significant amount of old cement mortar attached to the surface of recycled aggregate. This not only increases water absorption rate but also creates numerous weak interface transition zones in recycled concrete, greatly impacting its performance. By comparing and analyzing a large number of relevant literature on removing old cement mortar and enhancing the strength of recycled concrete interfaces, this paper examines their advantages, disadvantages, applicability, environmental benefits, etc., and proposes corresponding suggestions for developing recycled concrete aggregate technology. These findings aim to provide new insights into future research directions for reinforcing recycled concrete aggregates.
