Experimental Investigation On Light Weight Concrete By Uisng Paper Plastic Aggregates

Abstract

  Lightweight concrete (LWC) uses lightweight aggregates (e.g., expanded clay, perlite) and has benefits like low density and thermal insulation. This study focuses on using paper-plastic aggregates (PPA) to enhance LWC. Various PPA replacement ratios (0%, 50%, 75%, 100%) were tested for properties such as workability, compressive strength, and density. Results show that while PPA-based LWC reduced workability at higher content, it lowered density by 30%, providing a sustainable, eco-friendly construction solution.
