Fly Ash–Blended Plastic Aggregates in Cement Concrete and Its Performance at Elevated Temperatures

Abstract

Abstract In this study, an attempt was made to manufacture plastic aggregates (PAs) by blending fly ash with molten waste high-density polyethylene plastic (HDPE). Further, the suitability of such aggregates to replace natural aggregates (NAs) in cement ... Practical Applications Plastic aggregates (PAs) can replace natural aggregate in cement concrete and can make concrete lightweight because of their lower specific gravity. Manufacturing of PAs from waste plastic and fly ash will lead to hazardous waste ...
