Strength and abrasion resistance of palm oil clinker pervious concrete under different curing method

Abstract

This paper investigates the abrasion resistance and strength properties of pervious concrete (PC) containing palm oil clinker (POC) coarse aggregate under different curing method. Materials used include OPC Type I, 10mm nominal size POC coarse aggregate and granite. The palm oil clinker pervious concrete (POCPC) mixes were developed with a fixed water-cement ratio of 0.3 and was studied at various replacement levels of natural aggregate with POC aggregate (0%, 25%, 50%, 75% to 100%). Selected curing methods for the POCPC samples were full water curing, air curing and 3days water curing respectively. Based on results, compressive strength and abrasion resistance of the POCPC reduced, resulting from the incorporation of POC into the mix irrespective of the curing method. Given the selected curing method, POCPC cured in full water had superior performance in terms of compressive strength. However, the POCPC cured in air and 3days water curing recorded about 5% loss of its compressive strength with respect to full water curing due to uncontrolled temperature and humidity condition. Abrasion resistance of the concrete was improved when full water curing was adopted with about 5% loss due to curing method. Thus, it becomes evident that curing had marginal effect on the properties of the concrete rather it is dependent mainly on the properties of the aggregate. Furthermore, incorporating POC as an alternative concreting material can help to sustain the construction industry based on the sustainability efficiency evaluation conducted.
