摘要

Plastic consumption is increasing rapidly across the world, causing a major harm to the environment. This study proposes using shredded plastic waste in the production of concrete, and the mechanical properties of concrete containing shredded plastic waste, properties such as compressive strength and split tensile strength, are investigated. Several research works conducted in similar fields have found positive outcomes. The aim of this research is to conduct an experimental study by using recycled shredded plastic waste in the production of concrete. Concrete cube and cylinder specimens with grade C30 are prepared by using four mixes. The mix proportions of the control specimen with concrete ingredients such as cement, fine aggregate and coarse aggregate are 1:1.84:2.34 respectively. Mix 1 does not contain any shredded plastic waste. Mixes 2, 3, and 4 contain 0.5%, 1%, and 1.5% of shredded plastic waste according to the weight of the cement, respectively. The samples are prepared and cured for 28 days. Slump tests are conducted to measure the workability of fresh concrete. A compressive strength test and a split tensile strength test were conducted on hardened concrete. The slump value of mixes M1, M2, M3, and M4 were 25 mm, 20 mm, 35 mm, and 50 mm, respectively. The average compressive strength of mixes M1, M2, M3, and M4 is 30.40, 21.74, 26.85, and 24.03 MPa, respectively. The average compressive strength of mix 2 gives the lowest value of compressive strength among all the mixes. The average split tensile strength of mixes M1, M2, M3, and M4 is 2.85, 2.15, 2.50, and 2.15 MPa, respectively. Experimental results have shown that the concrete with 1% shredded plastic waste yields better results than those of other concrete mixes with shredded plastic waste.
