Abstract:This paper reports on using waste polyethylene to form plastic-bonded sand interlocking blocks for wall construction. The production process, mechanical properties, and failure mechanisms of three different interlocking block wall systems are reported. Plastic-bonded composite blocks were formed by mixing sand into waste polyethylene in a high-temperature extruder. The blocks formed had densities between 1.5 and 1.6 g cm−3 and compressive strengths of approximately 15.0 MPa. This is significantly higher than t… Show more
