Experimental investigation of influence of acid rain on leaching and hydraulic characteristics of cement-based solidified/stabilized lead contaminated clay

► Effect of acid rain on leaching and hydraulic characteristics. ► Leaching of calcium and lead are significantly affected by initial pH of acid rain. ► Decreasing rate of hydraulic conductivity is lower in acid rain case. ► Presence of SO42− in acid rain increased the leaching mass and rate of calcium.
