RADIATION SHIELDING CONCRETE COMPOSITION
Disclosed is a radiation shielding concrete composition. The radiation shielding concrete composition according to the present invention comprises: cement; general aggregate; a shrinkage reducing agent; waste glass aggregate; and an admixture for suppressing alkali silica reaction. The admixture for suppressing alkali silica reaction is to suppress alkali silica reaction due to the waste glass aggregate and comprises an absorption preventive agent made of any one or a combination of a PCE admixture, silane, siloxane, and polydimethylsiloxane (PDMS).
방사선 차폐용 콘크리트 조성물이 개시된다. 본 발명에 따른 방사선 차폐용 조성물은, 시멘트; 일반 골재; 수축저감제; 폐유리골재; 및 알카리 실리카반응 억제용 혼화제; 를 포함하고, 상기 알카리 실리카반응 억제용 혼화제는 상기 폐유리골재로 인한 알카리 실리카반응을 억제하기 위한 것으로, PCE 혼화제, 실란(silan), 실록산(siloxane) 및 폴리디메틸실록산 Polydimethylsiloxane; PDMS) 중 어느 하나 또는 이들의 조합으로 이루어지는 흡수 방지제를 포함한다.
