Abstract
In order to investigate the feasibility of municipal solid waste incineration ash melted slag powder as admixture, an experimental study was performed on cement mortar with municipal solid waste incineration ash melted slag powder. Fresh mortar properties and strength properties with various municipal solid waste incineration ash melted slag powder replacement ratios were estimated. There replacement ratio adopted in this study was 0, 10, 20, 30, 40, 50%. After then flow properties was considered as properties of fresh mortar. And compressive strength was determined 3, 7, 14, 28, 56 days for the hardened mortar specimens. According to the test results, the flow of mortar was increased with in replacement amount of municipal solid waste incineration ash melted slag powder. Furthermore, compressive strength at early age was decreased, whereas the compressive strength at the age of 28, 56day was increased.
본 연구는 쓰레기 소각재 용융슬래그 미분말을 혼화재료로 사용하기 위한 연구로 소각재 용융슬래그 미분말을 혼입한 모르타르에 대한 연구를 수행한 것이다. 쓰레기 소각재 용융슬래그 미분말의 혼입율을 10, 20, 30, 40, 50%로 다양하게 한 후 굳지 않은 모르타르의 플로 특성과 재령 3, 7, 14, 28, 56일의 압축강도를 평가하였다. 실험결과 쓰레기 소각재 용융슬래그 미분말의 혼입율이 증가할수록 유동성이 증가하였고, 3일, 7일의 압축강도는 점진적으로 감소하였으나, 재령 28, 56일 압축강도는 증가하는 것을 알 수 있었다.
