The accelerated carbonation on the properties of recycled concrete aggregates is important for the recycling of waste concrete, sequestration of CO2 and reduction of carbon emissions. In this review, the mechanism of accelerated carbonation on the recycled concrete aggregates and the physical properties and microstructure changes of recycled concrete aggregates enhanced by accelerated carbonation were introduced. Some factors for efficient CO2 treatment on the properties of recycled concrete aggregates were summarized. The physical properties, durability and microstructure improvement of recycled concrete containing CO2 treated recycled concrete aggregates were analyzed. In addition, the perspectives for future research were also proposed.
