Abstract | Most construction practices and materials used within the building and construction industry leave a large ecological footprint. In 2006-08, Australia generated 16 million tonnes and 2.3 million tonnes of construction and demolition (C&D) waste and plastic solid waste (PSW), respectively, and only about one-fourth of these plastic wastes were recycled. One of the best options to reduce C&D waste and increase the recycling rate of PSW is to convert these plastic wastes into recyclable building products. However, understanding on the structural behaviour of this new material is limited. This paper investigates the important structural properties of the recycled mixed plastics wastes containing high density polyethylene, low density polyethylene and polypropylene. The strength values were found to be 16.67, 29.58, 4.58 MPa in flexure, compression and shear respectively, while the modulus of elasticity is 1.1 and 0.55 GPa in flexure and compression respectively. These properties are comparable to virgin plastics and commercially grown softwood indicating the high potential of this emerging material for building and construction. |
