Abstract

The aim of the research is providing the application method of recycled materials to manufacture the low costed eco-friend block at currently operated concrete block plant. In this research, based on the previous research results on three types of slag cement with illite, desulfurized gypsum, and wasted refractory products, the actual block product was manufactured by the currently operated plant facility and evaluated their properties to suggest the optimal proportions. As an experimental results, in aspect of compressive strength, absorption ratio, freezing resistance, and pH, type III slag incorporating 5% desulfurized gypsum with 1% replaced illite as an aggregate could be suggested as am optimal proportion. In additionally, considering the high cost of the illite, it can be considered as an optimal proportion that type III slag incorporating 5% desulfurized gypsum for binder.

본 연구는 콘크리트 블록을 생산하는 공장에서 경제적이면서 환경 친화적인 블록을 생산하기 위해 산업부산물 자원을 효과적으로 이용하는 방안에 관한 것이다. 즉, BS 3종에 일라이트, 탈황석고 및 폐내화물울 치환하여 종전에 연구되었던 결과에서 양호한 것으로 밝혀진 몇 개 변수를 Mock-up 시험성격으로 실제 생산라인에서 호안블록을 생산하여 그 특성을 분석하므로써 최적 조합을 확정하고자 한다. 실험결과 압축강도, 흡수율, 내동해성 및 수질영향의 pH 관점에서 고려하면 BS 3종에 정제 탈황석고 5% 치환 및 여기에 골재로서 일라이트를 1% 치환한 배합이 최적인 것으로 분석되었다. 그러나 일라이트는 시멘트 보다 고가이므로 경제적인 측면까지도 고려하면 BS 3종에 5%의 정제 탈황석고를 결합재로 치환하는 배합이 최적 조합인 것으로 밝혀졌다.
