알루미늄 드로스 첨가를 통한 경량화벽돌의 물리적 특성평가

초록

In this work, lightweight brick was prepared from aluminum dross, MS and MBA. Aluminum dross is discharged as by-product through the process of aluminum smelting. It can be used as foaming agent, because it produces hydrogen gas due to the reaction with alkali activator. In this study, the specific gravity and compressive strength of prepared brick was discussed with the addition of aluminum dross. Compressive strength, flexural strength and specific gravity was 36 MPa, 2.6 MPa and 1.48 at mixing ratio of 0.9wt% aluminum dross, respectively. The physical property of brick was debased with the addition of aluminum dross. Because the pore size was bigger in accordance with the addition of aluminum dross.
