Abstract
Abstract In order to utilize waste materials as building component, waste of thin plastics wrap and waste engine oil without and with rice husk ash as filler can be used for producing Plastic Wall Block (PWB). The objective was to evaluate the PWB engineering properties. The waste plastic wrap was shredded or cut off to sizes about 5-10mm. The waste engine oil without or with rice husk ash were heated at 200°C, then the shredded plastic poured into hot oil and evenly mixed. The mixture was casted in a metal mould and compacted at temperature of 125-110°C using a Marshall hummer for one blow to give even and flat surface shape then cooled down to form sample with average size of 100x100x80mm. It was obtained that the soaked compressive strength can exceed 25kg/cm2 which is the minimum value targeted, with initial rate of suction range about 0.0149-0.1012 kg/m2.minute; porosity in a range of 0.62-1.48 %, and water absorption of 0.0481-2.2185 %.
