Comparative Analysis Of Compressive Strength Between Expanded Polystyrene (EPS) Concrete And Regular Concrete

Abstract

This study presents a comparative analysis of compressive strength in concrete utilizing Expanded Polystyrene (EPS) bubbles as partial percentage of coarse aggregates. The mechanical and durability properties of concrete incorporating expanded polystyrene bubbles as partial replacements for natural coarse aggregate are investigated. By partially replacing the fine aggregate with polystyrene bubbles, lightweight concrete with structural integrity and ease of handling is achieved, aligning with project specifications. Polystyrene, a lightweight material widely used in various technological applications, offers potential for producing non structural concrete. Experimental investigations were conducted, encompassing preliminary material tests and evaluations of compressive strength across varying densities of polystyrene aggregate concrete. The aim was to elucidate the relationships between engineering characteristics and performance. With growing demand for construction materials and a focus on reducing dead weight in taller structures, substituting polystyrene beads for fine coarse particles in concrete foundations is proposed. The primary objective is to identify concrete mix proportions that yield performance akin to foam concrete in the absence of polystyrene beads. Comparative analysis of sixteen concrete types will enable achieving this objective.
