Effect of expanded polystyrene beads on shear behavior

Abstract

EPS (Expanded Polystyrene) is a widely available polymer that may be used in concrete mixes. The prospect of employing EPS as an addition to improve the physical and mechanical characteristics of concrete is investigated in this research. The objective of this study is to explore an alternative to standard aggregates and innovative materials that can assist sustain the environment while also solving difficulties. A number of studies were carried out to better analyze the behavior of EPS lightweight concrete. Five different mixes were investigated, which include virgin EPS and recycled EPS, as well as adding additives such Steel Fibers to the mix (SF). The influence of these materials on concrete has been studied. The results showed that while adding EPS and recycled EPS may decrease the density, it has been demonstrated to have a detrimental impact on characteristics such as shear strength, flexural strength, compressive strength, workability, and splitting tensile strength. Steel Fibers was found to have some benefits, particularly in terms of split tensile and shear load capacity, but it was not enough to negate the effect of EPS.
