Expanded Polystyrene (EPS) that was used in the research work was in the form of ‘EPS Beads’ which were spherical in shape and size varied in between 6 mm to 8 mm in diameter. Beads were made up of pre-extended Polystyrene balls. It is non-hydroscopic and does not promptly absorb moisture from the atmosphere. Expanded polystyrene exhibits number of outstanding properties such as light weight, high strength, structural stability, economy, insulation, aging resistance, recyclability etc. Glass is completely recyclable since it is not damaged by everyday use. An experimental program was planned in which one lean concrete mix which did not include any percentage of crushed glass powder and Expanded Polystyrene beads. The other combination of Mixes was prepared with different combinations of crushed glass powder and Expanded Polystyrene beads were. Cylindrical specimens, Cubes and beams were casted to obtain different physical properties. Concrete mixes with 0%, 10%, 20%, and 30% of crushed glass powder as to replace some part of fine aggregate and 0%, 1.5%, 2.5%, and 3.5% of Expanded Polystyrene beads as to replace some part of natural coarse aggregates. Suitable quantities of super-plasticizer and materials are added to improve the workability and stability. The cylindrical specimens, cubes and beams will be tested after the recommended curing period of 7 days and 28 days respectively.
