Very large quantities of construction and demolition wastes and especially concrete wastes are produced yearly. Up to now, only a small fraction of these concrete wastes is re-used as recycled concrete aggregates (RCA) for the manufacture of concrete. In order to make good use of RCA in the concrete, it is very important to study the influence factor of the properties of RCA. In this paper, the influence of laboratory accelerated carbonation on the properties of recycled concrete aggregates has been studied. The results show that after the laboratory accelerated carbonation, the harden cement paste content of RCA measured by salicylic acid dissolution decreases, the density and specific surface area of RCA increase, and the porosity of RCA decreases, which leads to the reduction of water absorption of RCA.
