Concrete is one of the most widely used materials for various construction projects around the world due to its low cost, availability, durability and ability to withstand extreme weather conditions. Glass and plastic have become part of our daily lives, with continuously increasing annual consumption. Low density, high strength, durability, light weight and low cost are factors that have contributed to the increase in the consumption of glass and plastics. Generation of waste from glass and plastic products are increasing and disposal of the waste causes environmental issues. There are many researches that utilize these generated waste as construction material. This research focuses on the use of shredded plastic waste and green glass waste powder to replace coarse aggregate and cement in concrete. The grade chosen for the investigation was M20. The mechanical properties of glass powder based concrete were studied by replacing green glass powder at 5%, 10%, 15%, and 20% with the volume of cement and replacing 10% coarse aggregate by volume with waste shredded plastic bottle caps. The test specimens chosen for the research were cubes of dimension 150 mm x 150 mm x 150 mm, cylinders of dimension 100 mm x 200 mm, and beams of dimension 100 mm x 100 mm x 500 mm. Results indicate that workability of freshly prepared concrete using glass powder noticed shear collapse for all the mixes cast. The compressive strength was 10% higher than the conventional concrete whereas split and flexural strength were almost same as that of conventional concrete. Hence, an attempt can be made to use waste green glass and plastic in the preparation of routine concrete.
