DESIGN AND CHARACTERIZATION OF LIGHTWEIGHT CONCRETE USING EXPANDED POLYSTYRENE(EPS) BEADS
Lightweight concrete using Expanded Polystyrene (EPS) beads is an innovative construction material designed to reduce the self-weight of structures while maintaining adequate strength and durability. In this type of concrete, conventional aggregates are partially or fully replaced with EPS beads, which are lightweight, spherical particles made from polystyrene. The inclusion of EPS beads significantly decreases the density of concrete, making it suitable for non-load bearing walls, insulation layers, partition panels, and precast elements. The main objective of using EPS beads in concrete is to improve thermal insulation, reduce dead load, and enhance workability. Due to its low density, EPS concrete also provides good sound insulation and energy efficiency in buildings. The production process involves mixing cement, fine aggregates, water, and EPS beads in proper proportions to achieve the desired strength and workability.
