OIL PALM SHELL CONCRETE (OPSC): A SHORT REVIEW

With the increase of the world’s population, industrial development and the construction of housebuilding and infrastructure activities, the demand for construction material is increasing. Disposals of agricultural waste have been making serious damages to the environment. Thus, by replacing the conventional raw materials used in concrete today by agricultural waste will intensely decrease unwanted impacts caused by the current concrete industry. A novel replacement for the conventional aggregate in the past 4 decades has been the utilization of oil palm shells (OPS) in concrete. This paper reviews published reports on OPS being used as aggregate for concrete in its current stand. Physical properties of OPS, fresh properties of OPSC, mechanical properties of OPSC, Structural behaviour and OPS with other materials have all been reviewed in this paper. Recently, however, development in high yield oil palm fruit has led to waning compressive strengths. This review also indicates the necessity for new investigations based on the new fruit breeding type of oil palm tree which is known as Tenera OPS.
