Abstract
This paper reports the results of the investigation done on bricks made using bottom ash and fly ash. Bricks were made with various proportions of bottom ash, fly ash and cement. Tests for workability, density, strength, water absorption and ultrasonic pulse velocity (UPV) were conducted. Results show that the compressive strength ranged from 5.5 MPa to 11.68 MPa, maximum water absorption was 15.7% and the UPV ranging from 2260.2 m/s to 2916.1 m/s. The strength of bricks increases with the increase in fly ash; water absorption, and UPV with the increase in fly ash. It is concluded that bricks of good quality can be made using bottom ash and fly ash whereby contributing to sustainable development.
