Manufacture of the Non-Sintered Aggregate Using the Industrial By-products and the Municipal Waste Incineration Fly-Ash

도시 쓰레기 소각 비산재와 산업부산물을 이용한 비소성 인공골재의 제조

Incineration method of municipal solid waste is the general method for reduction it's quantity and weight. Municipal solid waste incineration ash is classified two general types of ash : fly ash((MWFA) and bottom ash(MWBA)). MWFA containing a high degree heavy-metal may give rise to a serious environmental trouble. Therefore, this study was carried out to examine utilization of fly ash. In this study, we tried to find the recycling method of fly ash as a environmental-friendly artificial aggregate. The artificial aggregate using fly ash was tested for the various aspects, including physical properties and environmental stability. The qualities of artificial aggregate are similar to it of lightweight aggregate, and the heavy metal leaching concentration are very lower than a limitation of KSLT and EP.
