Carbonation treatment of recycled concrete aggregate: Effect on transport properties and steel corrosion of recycled aggregate concrete

Old cement mortars attached on recycled concrete aggregates (RCA) seriously affects the durability of the recycled aggregate concrete (RAC). Revealing the variation of the transport properties of cement mortar after subjecting to accelerated carbonation treatment is crucial with respect to understanding the effects of carbonated RCA on the durability of RAC. In this paper, cement mortars were used to study the transport properties after they...
