CONCRETE ADMIXTURE FOR PREVENTING OF HEAVY METALS EXTRACTION FOR RADIATION SHIELDING MORTAR COMPOSITION

摘要

Disclosed is an admixture for suppressing heavy metal dissolution for a radiation shielding filler composition. The admixture for suppressing heavy metal dissolution for the radiation shielding filler composition according to the present invention is to suppress the heavy metal component of the waste glass aggregate blended in the radiation shielding filler composition comprising cement, waste glass aggregate and water. As the admixture to be added to the filling material composition, PCE admixture; And a heavy metal dissolution inhibitor comprising a combination of a co-polymer and a calcium aluminate compound.
