Making of Lightweight Concrete by using EPS Beads as Replacement of Coarse Aggregate

The expanded polystyrene is one of the most widely use plastic, the scale being several billion kilograms per year. The use of expanded polystyrene in construction has lot of advantages compare with the use of conventional material which results in sustainable future. EPS is used as lightweight weight aggregate to produce lightweight concrete with unit weight less than 1000 kg/m3 which make it as light weight concrete. Coarse aggregate is a major contributor for heavy weight of concrete as replacing it with EPS Beads result in the reduction of the density of concrete. The Expanded polystyrene beads are the material which substitutes in the place of coarse aggregate. The concrete consist of 10%, 25% 50% and fully replace by volume of coarse aggregate. The cubes were tested at 3d, 7d and 28d of curing. The main objective of this investigation to study the properties, such as density, compressive strength, water absorption and splitting tensile strength of lightweight Expanded Polystyrene (EPS) beads concrete.
