Utilization of Crushed Pet Bottles as Partial Replacement of Aggregate in Concrete

The consumption of plastic has grown substantially all over the world in recent years and this has created huge quantities of plastic-based waste. Plastic waste is now a serious environmental threat to the modern way of living. This research work demonstrates the possibilities of using crushed pet bottles as partial replacements of aggregate in concrete. This research work presents an investigation of compressive strength, of concrete by adding crushed pet bottles as partial replacement of aggregate in various percentages. The compressive strength development of concrete containing all types of PET-aggregate behaves like in conventional concrete, though the incorporation of any type of PET-aggregate significantly lowers the compressive strength of the resulting concrete. The PET-aggregate incorporation improves the toughness behavior of the resulting concrete. This behavior is dependent on PET-aggregate’s shape and is maximized for concrete containing coarse, flaky PET-aggregate. The splitting tensile and flexural strength characteristics are proportional to the loss in compressive strength of concrete containing plastic aggregates. Ordinary Portland cement in Concrete and an attempt has been made to investigate the strength parameters of concrete (Compressive Strength). For control concrete, IS method of mix design is adopted and considering this a basis, mix design for replacement method has been made. Five different replacement levels namely 5%, 10%, 13%, 15%and 20% are chosen for the study concern to replacement method. Large range of curing periods starting from 7days and 28days are considered in the present study. Cubes (150×150×150mm) with varying ratios of PET will be casted. Total no of cubes casted would be 42. The various tests would be performed to evaluate the action of these materials will be normal consistency, setting time, compressive strength, and water absorption. The study would be conducted in the framework of a research project aiming at improving the utilization potential of pet bottles.
