Sustainable utilization of mixed healthcare waste as aggregate in lightweight concrete mixes: Mechanical behavior, water absorption and leaching studies

Wastes generated from healthcare practices are a serious problem for humans as well as for the environment. In this study, an attempt was made to use mixed solid medical waste (WPN) which consisted of shredded waste plastic and chopped waste needles for partial replacement of natural fine aggregate (sand) in concrete mixes at 0%, 2%, 4%, 6%, 8% and 10% by weight.
