Concrete admixture for preventing of heavy metals extraction for radiation shielding mortar composition |
| abstract |
Disclosed is an admixture for suppressing elution of heavy metals for a filler composition for shielding radiation. The admixture for suppressing the elution of heavy metals for the radiation shielding filler composition according to the present invention is used to suppress the elution of the heavy metal components of the waste glass aggregate blended in the radiation shielding filler composition comprising cement, waste glass aggregate and water. As an admixture added to the filler composition, a PCE admixture; And a heavy metal elution inhibitor formed of a combination of a co-polymer and a calcium aluminate compound. |
