China and other developing countries are the largest consumers of concrete. The massive use of concrete consumes natural resources and produces construction waste, which leads to the shortage of landfill sites. Using recycled aggregate to prepare concrete cannot only meet the performance requirements of natural aggregate concrete, but also solve the problem of insufficient landfill site, which is in line with the essence of sustainable development. However, the interfacial transition zone is often the weak area of recycled concrete, which is the focus of current research. This paper summarizes the mechanical properties of recycled concrete ITZ, studies the existing problems, and looks forward to the future development trend.
