Study on the effect of chloride ion ingress on the pore structure of the attached mortar of recycled concrete coarse aggregate

In this study, based on the porous interface of recycled aggregates (RA), the effects of chloride ion (Cl−) ingress by drying-wetting cycles on the pore structure of recycled aggregate concrete (RAC) with a full replacement ratio under different temperatures conditions were investigated. Changes in the pore structure of the old and new mortars were determined by mercury intrusion testing. The surface morphology and morphological characteristics...
