It is important to find a possibility for utilizing coal-preparation refuse (CPR) generated from coal mines in terms of environmental and economic points of view. In this study, a possibility for manufacturing fired clay bricks (FCBs) by CPR instead of clay was investigated. Firing shrinkage ratio, compressive strength, and water absorption ratio of test samples manufactured using CPR in the open air were measured. It was found that firing shrinkage ratio and compressive strength decrease with increasing the addition amount of CPR, while water absorption ratio is almost constant under the entire addition amount ranges of that. The test sample manufactured was nearly similar to the 1st grade clay bricks of Korea Standard L (ceramics) 4201.
