In housing construction, concrete are materials that will be used extensively to produce a wall structure that accommodates the load. However, the problem is the cost of producing by using natural resources, as it is a major mineral is difficult to find sufficient natural aggregate supply sources since high demand. Therefore, the lack of natural aggregate and its increasing demand leads to an alternative to be developed to replace the natural aggregate. This study investigated the effect of utilization of waste clay brick in Self Compacting Concrete (SCC) on its properties and performance. The waste clay brick (WBS) was replaced as fine aggregate in SCC from 10% to 30%. As the amount of waste clay brick in SCC increases, its workability and also Ultrasonic Pulse Velocity (UPV) quality decreases while the water absorption increases. The highest average compressive strength achieved was 43.3 MPa and for splitting tensile strength was 12 MPa respectively; both at 25% of WCB replacement. All test results showed that the optimum percentage to replace waste clay brick in SCC is 25% and it has the potential to be replaced as fine aggregate in SCC.
