- W2056539493 abstract "최근, 콘크리트 산업에서는 <TEX>$CO_2$</TEX> 배출량감소등 환경문제와 함께 부존자원의 고갈대책도 중요한 문제점으로 제기되어, 이를 동시에 해결하기 위하여 각종 산업부산물이나 산업폐기물을 콘크리트용 자원으로 재이용하는 방법이 연구되고 있다. 본 연구는 고로슬래그 미분말(BS)과 순환잔골재(RFA) 혼합 모르타르를 기반으로 하여 BS의 잠재수경성 반응을 탈황석고(FGD)와 보통포틀랜드 시멘트(OPC)의 자극반응으로 추가 활성화시킴으로써 일반 강도영역까지의 모르타르 활용성을 검토하고자 하였다. 결과적으로, BS에 FGD 10%, OPC 30%를 치환하고 RFA를 사용할 경우 OPC만을 사용하는 플레인 모르타르의 80%정도인 보통강도모르타르가 발휘되었지만 실용적인 측면에서 유동성적으로 플로치를 동일하게 유지하는 물-결합재를 낮춰 주게 된다면 더욱 플레인 강도영역에 근접할 수 있을 것으로 사료된다. As a solution of both environmental issue of reducing carbon dioxide emission and sustainable issue of exhausting natural resources, in concrete industry, many research on recycling various by-products or industrial wastes as the concrete materials has been conducted. The aim of this research is feasibility analysis of additional reaction with ordinary Portland cement and flue gas desulfurization gypsum based on the blast furnace slag and recycled fine aggregate based mortar to achieve the normal strength range. Consequently, in the case of mortar replaced 10% FGD and 30% OPC for BS, 80% of plain OPC mortar's compressive strength was achieved. Furthermore, when the water-to-binder ratio is decreased to keep the practically similar level of flow, it is expected to be achieve the equivalent compressive strength to plain OPC mortar." @default.
