Abstract
The accumulation of waste plastic worldwide creates serious environmental concerns. In the present study, efforts were made to utilize shredded plastic bags as concrete additive materials. Therefore, the workability, density, compressive and flexural strength, water permeability, static and dynamic modulus of elasticity and abrasion resistance properties of concrete were investigated in this study by adding different percentages (0, 0.5, 1, 2, 3 and 5%) of waste plastic bags by weight of concrete. The addition of waste plastic bags decreased the flow ability of fresh concrete and also resulted in loss of hardened concrete properties. The waste plastic concrete samples showed an improved resistance against the abrasion behavior. Microstructure study was also conducted using the optical microscope. The overall results indicated that the waste plastic concrete can be used for non-structural works.
