The purposes of this study were 1) evaluating the influence of the recycled aggregate on permeability and strength of concrete, and 2) decreasing the permeability and increasing the strength of recycled aggregate concrete. In the experience using five types of recycled aggregates, the influences of recycled aggregate on Clpenetration depth, carbonation depth, tensile strength and compressive strength were measured and compared. After evaluating two ITZs in recycled aggregate concrete, the relations between permeability or strength and ITZs were explained. Moreover, based on the above discussions, the method for decreasing permeability and increasing strength of recycled aggregate concrete could be proposed and proved.
