Abstract
This paper presents the feasibility of incorporating ultrafine particles collected in the separator bag filter (separator bag filter cement, SBFC) during the cement manufacturing process as an substitution material for cement. SBFC does not require additional processes needed in the existing processes to manufacture high early strength cement such as modifying mineral components and adjusting the firing temperature. Moreover, it can also solve the issue of efficiency decrease resulted from the increase of the grinding time applied in the existing process of manufacturing microcement. Therefore, this research has examined the characteristics of SBFC and fresh properties and mechanical properties after making paste and mortar using SBFC in order to use SBFC as a material to gain early strength of concrete. For results, analyzing the chemical composition and physical properties of SBFC, its blaine value was
본 연구에서는 SBFC의 기본 성능을 분석하고, 페이스트 및 모르터에서의 공학적 특성을 검토하여, 향후 경제적인 조강콘크리트 개발을 위한 방안으로 활용하고자 하였다. 실험결과 SBFC의 우수한 조기강도 발현 성능을 확인 할 수 있었고, 유동성을 고려했을 때 OPC와 SBFC와의 적정 혼입율을 도출하여 사용하는 것이 바람직 할 것으로 판단된다.
