WHITE CEMENT COMPOSITION COMPRISING CALCIUM CARBONATE
The disclosed content relates to a white cement composition containing calcium carbonate, and to a white cement composition containing calcium carbonate that is eco-friendly and economical by using fine powder of blast furnace slag, which is an industrial by-product, and calcium carbonate, which is collected from carbon dioxide, as main raw materials. The white cement composition containing calcium carbonate includes 60-75 wt% of blast furnace slag fine powder, 8-12 wt% of calcium carbonate, 6-8 wt% of lithopone, 3-6 wt% of silica, 4-5 wt% of quicklime, 1-3 wt% of sodium sulfate, 2-3 wt% of calcium chloride, and 1-3 wt% of white pigment, and has a whiteness of 89-98, a compressive strength of 43-46 MPa when cured for 28 days, and a stability of 0.5-0.59 %.
개시된 내용은, 탄산칼슘을 포함하는 백색시멘트 조성물은 산업 부산물인 고로슬래그 미분말에 이산화탄소 포집물인 탄산칼슘을 주원료로 사용함으로써 친환경적이며 경제적인 탄산칼슘을 포함하는 백색시멘트 조성물에 관한 것이다. 이러한 탄산칼슘을 포함하는 백색시멘트 조성물은 고로슬래그 미분말 60~75중량%, 탄산칼슘 8~12중량%, 리토폰 6~8중량%, 실리카 3~6중량%, 생석회 4~5중량%, 황산나트륨 1~3중량%, 염화칼슘 2~3중량% 및 백색안료 1~3중량%를 포함하되, 백색도는 89~98이고, 28일간 양생 시 압축강도는 43~46MPa이며, 안정도는 0.5~0.59%이다.
