Abstract : As oil palm is one the most essential product of Malaysia, it generated high amounts of waste. This paper presents a research investigation of the Oil Palm Ash (OPA) utilisation to partially replace sand in sand-cement bricks. The objectives are to obtain the optimal design mix of oil palm bottom ash as a partial replacement for the fine aggregate in sandcement bricks based on its workability during the fresh stage and to analyse the density and compressive strength of sandcement bricks that contain different percentages of OPA. Laboratory tests were carried out with OPA partial replacement percentages of 0% (control), 10%, 30% and 50%. Compressive strength tests were done on Day 1, Day 7 and Day 28 of the full water curing regime. The resultshows that the higher the percentages of OPA replaced sand in cement brick mixture, the higher the water-to-cement ratio is required to fulfil the targeted fresh concrete workability.It was also proven that OPA as the replacementin sand-cement brick will reduce the density and compressive strength of the brick. The highest strength developed by the OPA brick is on Day 28 and with 10% of the OPA replacement level which was achieved at 8.50MPa.
