무연탄 Bottom-ash를 적용한 저강도 고유동 충전재의 성능 평가

Evaluation of the Efficiency of Controlled Low-Strength Material Applied Bottom Ash of Anthracite Coal

In this study, the physical and dynamic characteristics of Bottom-ash produced at steam power plants were compared and considered. The comparative objects were Bottom-ash in which a lot of powder contained and that in which less than that relatively contained. The difference in quantity of powder showed different effect on the character of flow. This study was undertaken on the use of Bottom-ash as a fine aggregate, and showed the durability and the character of strength according to each rate.
