Abstract - In this project, the results of a pilot study were
pollution. Plastic waste is now so universal in the natural environment that scientists have even suggested it could serve as a geological indicator of the next era.[3]
conducted to study the effects when the use of plastic waste in concrete as a replacement for fine aggregate. This study takes advantage of plastic waste to propose an environmentally friendly solution to address the plastic waste problem. In this experimental study, the replacement was done at 0% 1% 2% 3% and an optimum proportion of plastic was estimated based on compressive strength test results. Replacement results were comparable with the controlled mix results in terms of compressive strength test result, 2% replacement showed a considerable amount of increase in compressive strength, and further addition of plastic decreases the compressive strength. Key Words: strength.
1.2 Objectives The aim of the experimental study is the use of plastic waste in concrete as a replacement of fine aggregate. This was done to reduce plastic waste, preserve the environment, and do something innovative and new in concrete. The results of the study gave the possibility of using plastic waste as building materials.

Plastic, Waste, Concrete, Compressive
The main objective of this study is
1. INTRODUCTION
1. to study the use of waste plastic materials in concrete mix and finding the strength and workability results of waste plastic reinforced concrete and conventional concrete.
1.1 General Polymers are the main component of the diverse class of synthetic or semi-synthetic materials known as plastics. Plastics can be moulded, extruded, or pressed into solid objects of many shapes because of their fluidity. It has gained popularity due to its versatility as well as several other attributes, such as being strong, lightweight, flexible, and reasonably priced to produce. Usually, plastics are produced using human industrial systems. [1]
2. The different percentages of waste plastic reinforced concrete used in the experimentation are 0%, 1%, 2%, and 3% with C25 mix concrete. 3. The results are compared with the plastic reinforced concrete produced and conventional concrete
2. LITERATURE REVIEW
Natural, organic materials like cellulose, coal, natural gas, salt, and, of course, crude oil are the raw materials used to make plastics. Before it can be used, crude oil must be processed because it is a complicated mixture of thousands of different compounds. Crude oil is first distilled in an oil refinery before plastics are made. By doing this, the heavy crude oil is separated into fractions, which are collections of lighter components. Each fraction is a blend of hydrocarbon chains, which are chemical compounds composed of hydrogen and carbon. The molecules in these chains vary in size and structure. Naphtha, one of these fractions, is an essential substance for making plastics.[2]
P. Pooja (2019), According to this study, one of the main issues that arises in every nation is the disposal of plastic. According to government statistics, over 15,000 tons of plastic waste are produced daily in India, with 6,000 tons going uncollected and ending up in the streets. Reusing large waste is thought to be the most environmentally friendly way to address the disposal issue. Plastic is one such waste that has several potential uses. In this project, it was discussed about the behaviour of concrete with partial replacement of fine aggregate with plastic wastes ranging from 15-30% with small grain size incorporated and 20% replacement showed a considerable amount of increase in compressive strength, and further addition of plastic decreases the compressive strength. [4]
The world is facing a global plastics crisis. Out of the 8.3 billion tons of plastics produced since the 1950s, there is virtually no place on Earth which is left untouched by plastic
