Concrete is abundantly used building material on the planet, requiring around 12.6 billion tons of natural resources to produce. All of the elements in concrete are partially or completely replaced by a variety of waste products, such as fly ash, rice husk ash, wheat straw ash, and so on. Rapid urbanization and industrialization around the world has resulted in large amounts of plastic trash and waste tyre rubber being deposited. This trash can be used to lower the coarse aggregate content of concrete when used in the proper conditions. This research work looks at the potential of a novel compound GPRA i.e. (Glass, Plastic, Rubber, Aluminum) as a partial replacement in coarse aggregate. Though there has been enough research on use of waste materials as replacement in concrete structures with an aim to curb pollution levels. This research work aims to utilize properties of waste materials which may give a higher performance than individually using of waste materials and while lowering of various pollution levels with cost effective ways for partial replacement of coarse aggregates in concrete, shredded waste materials for GPRA with sizes ranging from 4.75 to 20 mm will be employed. This investigation will use an M30 design mix with a target mean strength of 42 n/mm2. GPRA will be used to partially replace coarse aggregate in the following percentages: 10%, 30%, and 40%. The C.S., S.T.S., and F.S. of GPRA in hardened concrete has to be compared to the individual replacement of these waste materials.

This process causes a number of concerns, including a shortage of construction supplies and increasing waste and other non-biodegradable components. Wastes of many forms are produced as human race of infrastructure goes on. Waste disposal has become a concern as a result of the emergence of non-decaying and low biodegradable waste products, as well as an increasing consumer population. With increased development comes an increase in construction costs and pollution. Engineers and designers have been on the lookout for new ways to incorporate waste materials into cement concrete blocks. Concrete is a composite material that is made up of C.A. and cement. The coarse aggregates used in concrete production are either naturally occurring or crushed rock, which is not readily available in all construction areas, raising the cost. Partially replacing C.A. is an alternative to this problem. Although glass makes up around 5-10 % of municipal solid waste, only a small portion of it is recycled. It is estimated that several million tonnes of waste glass is generated annually around the world as a result of population increase, rising living standards, industry, and urbanisation. Year by year, the use of rubber products grows in popularity around the world. In many Indian cities, discarded tyres constitute a big environmental issue. In India, more than 1 billion trash tyres are produced each year, or around one tyre per person. Approximately 80% of scrap tyres are disposed in landfills. It is not only inefficient, but also costly, to bury scrap tyres in landfills. Landfilling of entire or shredded tyres is prohibited under recent EU laws on waste disposal (Council Directive 1999/31/EC). From 1950 to 2018, an estimated 6.3 billion tonnes of plastic were produced worldwide, with 9 percent recycled and the remaining 12 percent burnt. In India, more than 5 MT of plastic are used each year, with only about a one fourth being recycled and the rest ending up in
