PERFORMANCE OF BRICKS MADE FROM FLY ASH AND BOTTOM ASH
This paper presents the findings of an investigation carried out on bricks made using fly ash and bottom ash using a non-conventional method. This investigation was carried out to meet two main objectives; one to produce environmental and eco-friendly type of bricks, second to produce more economical bricks. The casting of bricks was made using self-compacting mixture of raw materials eliminated either pressing or firing. Then the bricks were tested for strength, UPV and water absorption. The compressive strength range between 4 MPa – 11.3 MPa, while water absorption range between 14.8% - 8.8%, showing a promising opportunity for such idea. The optimum ratio of bottom ash, fly ash and cement was found to be 1:1:0.35 with regard to the performance of hardened bricks. It is indicated that bricks developed in this study can be used as an alternative to conventional bricks.
