PLASTIC MIX CONCRETE BY USING WASTE PLASTIC POWDER AND PLASTIC GRANULES WITH WORKABILITY TEST

Plastic mix concrete is an eco friendly concrete which is more effective used in sanitation which can reduces the bacterial effects and increases the ground water level. One of the waste materials used in this concrete mix is ‘Plastic’. The plastic materials used for concrete mix are waste plastic powder and plastic granules. The main aim of the study is to investigate the change in mechanical properties of concrete with addition of plastics in concrete. Usually, M20 concrete is used for most of the constructional works, hence in this project M20 concrete is taken and waste plastics is used as a modifier. Modifier was added in percentage such as 3%, 5%, 10%, 15% in order to replace the same amount of cement and fine aggregates. Tests were conducted on coarse aggregates, fine aggregates, cement and modifiers (waste plastics) to determine their physical properties. These tests were conducted at room temperature and these tests include performing slump, fresh density, dry density, compressive strength. Cubes were casted and tested for 7 & 28 day’s strength.
