The Effect of Recycled HDPE Plastic Additions on Concrete Performance

This study examined HDPE (high-density polyethylene) plastic waste as an added material for concrete mixtures. The selection of was based on its increased strength, hardness, and resistance to high temperatures compared with other plastics. It focused how can be used additive in increase tensile strength compressive strength. 156 specimens were identify the effect adding different percentages sizes lamellar particles lower, medium, higher non-structural applications. 0.5 mm thick 10 × mm, 5 20 2.5 40 at 2.5%, 5%, 10%, 20% by weight cement. results showed that medium class (with equal MPa) had best response addition HDPE. 5% represented optimal mix all types, while size best.
