Abstract
This study is the study desiring to solve the problem by utilizing the kinds of recycled resources considered to be troubled complementarily. Namely the reaction of potential hydraulicity of Blast Furnace Slag Powder (BS) shall be reacted with the alkali of Recycled Fine Aggregates Coarse Aggregate, it has been experimented to obtain the optimum value with the replacement ratio of incineration plant ash (WA) treated with the slaked lime as the experiment variable by solving the alkali of shortage with the Ordinary Portland Cement (OPC). As a result, the liquidity and the air volume are declined slightly as the replacement ratio of incineration plant ash WA increases, the mixture of incineration plant ash WA 1% has been analyzed to be the most suitable considering the viewpoint of effective handling of waste as the compression and the tensile strength showed the maximum value before and after 1% even though it was disadvantageous with the increase of chloride content.
연구에서는 문제시 되는 순환자원의 종류를 상호 보완적으로 활용하여 문제를 해결하고자하는 연구이다. 즉, 고로슬래그 미분말(BS)의 잠재 수경성반응을 순환 잔 굵은 골재의 알칼리로 반응시키고, 부족분의 알칼리를 보통포틀랜드 시멘트(OPC)로 해결하면서 소석회 처리된 소각장애시(WA)의 치환율을 실험변수로하여 최적치를 구하고자 실험하였다. 실험결과 WA 치환율이 증가할수록 유동성과 공기량은 약간 저하하고, 염화물량은 증가하여 불리하였지만 압축 및 인장강도가 1% 에서 최대 값을 나타내어 폐기물 유효처리 관점까지도 고려하면 WA 1% 혼합이 최적인 것으로 분석되었다.
