Comparative Analysis Of Compressive Strength Of Concrete By Utilizing Polystyrene Bubbles As Partial Replacement Of Fine Aggregate.

Abstract

This study presents a comparative analysis of compressive strength in concrete utilizing polystyrene bubbles as both coarse and fine aggregates. The mechanical and durability properties of concrete incorporating polystyrene bubbles as partial replacements for natural fine 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.
