Properties of Plastic Bounded Agricultural Waste Composites II: Physical Properties of Some Composites

Abstract

Twenty six (26) plastic bounded composites, one unfilled and five each filled separately with varying contents of cement, limestone, silica-sand, drainage san granite have been formulated and compounded. Their percentage water absorption was determined. Composites % water absorption was determined. Composites % shrinkage range from (0.86-8.00) % and % water absorption from (1.03-15.00) %. These results suggest that the composites under study meet the allowable American Standard for Test Measurement (ASTM) for floor and wall tile tiles maximum 15% shrinkage and maximum 16% water absorption. If these composites are examined for mechanical strength, they may be found useful in the building industry for the manufacture of floor and wall tiles. Using spent pure water (thermoplastic) may result in the control of environmental pollution caused by the non-biodegradable spent plastic.
