The massive generation of concrete wastes occupies land resources and causes environmental pollutions. Recycling concrete wastes back to the construction industry can relieve pressures caused by shortages of natural resources, and solve some environmental problems. This review represented the research progress on the key technologies of re-utilizing recycled coarse aggregates (RCAs), recycled concrete fines (RCFs), and recycled concrete powders (RCPs), mainly including the strengthening and modification of RCAs and RCFs through accelerated carbonation, the direct re-activation of RCPs, and its value-added applications. The mechanisms and practical application both were discussed, and the results indicated that the full utilization of concrete wastes could reduce the consumption of river sand, natural gravels, limestone and clay and sequestrate CO2, thus promoting the carbon neutrality.
