An experimental program was conducted on partial substitution of lightweight aggregates with recycled plastics in lightweight concrete. Bridging cracks in the brittle concrete matrix by soft synthetic inclusions led to the material's enhanced toughness and increased resistance to shrinkage cracking. Plastics also enhanced the impact resistance of lightweight concrete and produced desirable permeability characteristics and acceptable compressive strength-to-unit weight ratios. Because of the desirable performance characteristics of concrete materials incorporating mixed recycled plastics, such materials are expected to have environmental, economic, and technical benefits.
