Experimental study on partial replacement of fine aggregate by Expanded polystyrene beads in concrete

Abstract

In the world of construction, concrete is the most crucial component. The construction industry's growing search for environmentally friendly and sustainable materials has prompted research on using some waste materials to partially replace the traditional components of concrete. Expanded Polystyrene (EPS), a non-biodegradable waste product from the packaging sector, is used in our project work. In order to reduce the concrete's self-weight, design must be based on density. Concrete that is lightweight and capable of achieving a dependable, respectable compressive strength can be made by partially or entirely substituting the expanded polystyrene with normal aggregates. Substitution of different eps bead percentages in accordance with desired design elements for various proportions. To determine concrete's mechanical and physical characteristics at ages (7), (14) and (28) days, several tests were performed on fresh and hardened concrete. The findings shows that as the quantity of EPS increases, concrete's strength would decrease as the density is decreased.
