Concrete is a composite material created from Cement, fine aggregate, coarse aggregate, admixture. Nowadays the requirement of materials for concrete is high but the availability is less. Therefore the replacement for cement and sand are being done by fly ash, GGBS, and PET plastic pieces which in-turn will help both environment and construction industry. As we know, Fly ash is a by-product of coal combustion and causes harm to both environment and society. The disposal of fly ash is costlier when compared to replace it in construction activities. Therefore 30% of Fly ash is replaced with cement in this experiment and study the properties of concrete. GGBS is obtained by quenching of molten slag, which is in powdered form, In concrete, it helps to decrease the damages caused by an alkali-silica chemical attack and also gives higher attrition to chloride. Therefore 20% of GGBS is replaced with cement along with Flyash. Plastic as a material is a major challenge to the environmental pollution in which PET plastic is also a part. Therefore to use PET plastic in concrete could be a solution in solving an environmental problem. In this experiment 10%, 12%, 14% and 16% of PET Plastic are replaced to fine sand as an alternative source. To help gain the tensile strength of concrete Recron 3s fibres are added at 0.25% of the volume of cement. It is expected to show sufficient deflection before failure of concrete. The concrete with all the additives and proper design mix.will be tested for compressive, Split tensile and flexural strength is tested for 3, 7 and 28 days.
