Abstract
Plastic wastes are growing fast and affecting the environment negatively. Thus, finding different methods of disposing of is becoming a major concern. This research aimed to minimize the plastic by recycling it into construction materials. For this, grinding high-density polyethylene (HDPE) was mixed with cement at different percentages to produce plastic bricks. The compressive strengths, density, and water absorption capacity were investigated. The compressive strength was found within the recommended value (2000 psi) up to 35% mixture of HDPE. The addition of HDPE with cement decreased the density, increased the ductility, and improved the workability which led to producing lightweight materials.
