STABILIZATION AND SOLIDIFICATION OF Pb IN CEMENT

Why should concrete be cured what is curing what benefits are there to curing concrete and how is it doneConcrete curing is a process in which the cement and the water in concrete bond and harden through a chemical reaction called hydration As they bond the Stabilization/solidification S/S processes are routinely used for the final effect of cement cure time on Pb metal leaching and on the matrix compressive
