Lightweight concrete has gained significant attention in the construction industry due to its numerous benefits, such as reduced dead load, improved thermal insulation, and enhanced seismic resistance. One popular approach to achieve lightweight concrete is by incorporating expanded polystyrene (EPS) beads into the mixture. EPS beads are lightweight, closed-cell beads made from expanded polystyrene foam, which possess excellent insulating properties. Normal concrete has a viscosity of 24- 25 kN/ m3 which increases the tone load of the structure and also makes it uneconomical. To reduce the weight of the structure light EPS beads concrete is used. One of the styles to produce light concrete is to use Expanded Polystyrene globules as a partial cover to fine total. The main ideal of this disquisition is to gain light EPS beads concrete and also to determine the optimum lozenge of Expanded Polystyrene globules. In the present work the Expanded Polystyrene beads are added at 10 %( by total volume of fine total) and their parcels similar as viscosity and compressive strength are studied. From the results attained it's observed that an optimum of 40% of Expanded Polystyrene beads can be replaced by volume of fine total which gives a strength of 21 N/ mm2 for M20 grade concrete It can be used for simple concrete building, where M20 concrete is liked after testing of 7 and 28 days.
