Reuse of high-density polyethylene waste in concrete mixes.

Abstract

:high -density polyethylene waste in the environment is regarded as an extensive problem because of
very slow degradation and the very existence of large quantities of these waste’. So, finding alternative
approaches to disposing of waste by using friendly processes is becoming an essential research case. In the
present research, coarse aggregate in concrete was exchanged with high- density polyethylene waste with the
ratios of 0.1,0.25,0.5,0.75 and 1 for safe disposal of these wastes and the production of lightweight and lowdensity
concrete as a compared to concrete free from waste. This study was conducted using high-density
polyethylene residues from which fruit and vegetable cages are made. The results showed a gradual decrease in
the density of the models, with an increase in the percentage of high-density polyethylene wastes, which led to
obtaining light concrete, and a change in compressive strength values and fracture strength values at the age of
Seven and Twenty-eight days.
