Abstract
In this study, the utilization possibility of coal-preparation refuse emitted from Hwasun coal mine in Korea as a raw material for ceramic body was investigated. The firing shrinkage ratio of ceramic specimen made from the coal-preparation refuse was reduced with increasing the addition amounts of that, while the compressive strength was slightly decreased. The weight of ceramic body was also reduced because carbon contained in the coal-preparation refuse was burn by fring. The water adsorption ratio of the ceramic specimen was under 10 wt%, and the compressive strength of that was over 21 MPa at over $1,150^{\circ}C$ for 2 hr. Therefore, it was possible to make the 1st garde clay brick of KS L 4201 from the coal-preparation refuse.
