Over time, the cost of construction kept increasing due to high cost of aggregates. Serious environmental concerns have been raised on the ineffective management of the plastic waste generated globally and which has caused environmental, ecological and economic sabotage. Interest in the environmentally friendly recycling of plastic waste as materials for concrete is being considered. This study investigates the performance of concrete with addition of plastic Poly ethylene terephthalate (PET) aggregate. The plastic PET aggregate was used as substitution for coarse aggregate at 10%, 20% and 30% replacement levels. Effects of the presence of plastic PET aggregate in concrete on workability, density, compressive strength, flexural strength and water absorption were determined. Keywords: alternative materials; compressive strength; environmental impact; coarse aggregate; flexural strength; and plastic pet aggregate.
