چکیده انگلیسی
Palm oil clinker (POC), a by-product of palm oil mill, can be found in large quantity in Malaysia and it is considered as waste. POC is suitable as aggregate replacement in lightweight concrete and other engineering applications due to its physical properties. This study presents the use of POC as coarse aggregate in the production of pervious concrete (PC). Materials used include OPC Type I, coarse aggregate 10Â mm nominal size. Based on this, various mixes were developed with a fixed water-cement ratio of 0.3. The palm oil clinker pervious concrete (POCPC) were studied at various replacement levels of natural aggregate with POC aggregate ranging from 0% to 100%. Results indicated that substitution with POC reduced the compressive strength and density of the concrete. However, the coefficient of permeability and porosity rose. Compressive strength obtained was between 3.43Â MPa and 9.52Â MPa. Maximum loss in strength was about 65% at full replacement. However, replacement of POC at 25% exhibited a superior performance among others. As such, it has been identified as the best mix for optimum performance of the POCPC.
