Abstract

This study evaluates engineering properties of mortar using lightweight fine aggregate made by bottom ash discharged air cooling process according to grading. Then we confirm possibility of use as lightweight fine aggregate. Consequently, Mix using bottom ash need additional examination for a change with the passage of time of flow. Also, mix of S indicates similar compressive strength with mix of Plain and 16% decrease of unit weight compared to mix of Plain; while mix of B indicates 10% decrease of compressive strength and 16% decrease of unit weight. Therefore, this study shows that mix of S and B is superior compared with other mix.
