Abstract

In this study, the compressive strength of HDPE-Plasto Sand Aggregate (HDPE-PSA) concrete has been investigated, where the rough surface aggregates have been prepared by melting the High-Density Polyethylene (HDPE) plastic in the 1:1, 1:2, 1:3 and 1:4 ratios with sand. In this way, the aggregates made of HDPE-PSA had lower density and specific gravity than natural aggregates and were classified as lightweight aggregates. For the concrete mix design, 0.40 and 0.65 w/c ratio used. we adhered to the ACI 211.2-98 (re-approved 2004) code. An accelerated curing tank was used in order to determine the compressive strength. Overall, the study reveals that HDPE-PSA aggregates hold promise for creating concrete with appropriate compressive strength, offering a novel solution to recycling plastic waste and promoting sustainable construction practices. The incorporation of HDPE-PSA aggregates in concrete is a step toward sustainability and a potential substitute for traditional aggregates, which is in line with the global trend towards greener construction practices and circular economy.
