CONCRETE ADMIXTURE FOR INHIBITING OF ALKALI AGGREGATE REACTION FOR RADIATION SHIELDING CONCRETE COMPOSITION

摘要

Disclosed is an admixture for inhibiting an alkali silica reaction for a radiation shielding concrete composition. The admixture for inhibiting an alkali silica reaction for a radiation shielding concrete composition according to the present invention is added to a concrete composition, which comprises cement, normal aggregate, waste glass aggregate and water, to inhibit an alkali silica reaction caused by the waste glass aggregate. The admixture comprises: a PCE admixture; and an absorption inhibitor consisting of any one of silane, siloxane and polydimethylsiloxane (PDMS) or combinations thereof.
