Abstract - Plastic is one of the most widely used material in
the modern world because of its lightweight and durability. it is replacing other materials. Plastic is a non-biodegradable substance which creates land as well as water pollution to the environment. The quantity of plastic waste is expanding rapidly which is great threat for the environment. In this research work an attempt has made to utilize HDPE waste plastic in manufacturing plastic sand bricks by using 600µm and 4.75mm sand respectively. The plastic sand bricks have been carefully studied and compared with locally available conventional clay bricks. The compressive strength was found more for the plastic sand bricks for proportion of 1:4 and with 4.75mm sand. Plastic sand Bricks also gave good results in Impact test, Soundness test and Hardness test. Plastic sand bricks can be a good alternative to locally available conventional clay bricks to reduce the consumption of natural resources such as clay and for efficient and effective utilization of waste plastic for a healthy environment. Key Words: HDPE, Plastic Sand Bricks, 600µm sand, 4.75mm sand.
1. INTRODUCTION The term “plastic’’ is derived from the Greek word ''plastikos'', meaning fit for moulding. Plastics are versatile, hygienic, lightweight, flexible and highly durable. The world's first fully synthetic plastic was Bakelite, invented in New York in 1907, by Leo Baekeland who coined the term 'plastics'. Many chemists have contributed to the materials science of plastics, including Nobel laureate Hermann Staudinger who has been called "the father of polymer chemistry" and Herman Mark, known as "the father of polymer physics. Plastic is material consisting of a wide range of synthetic or semi-synthetic organic compounds of high molecular mass and often contain other substances that are malleable and so can be moulded into solid objects. Plastics are made from natural materials such as cellulose, coal, natural gas, salt, crude oil, minerals and plants through the polymerisation or polycondensation process. They are usually synthetic, most commonly derived from petrochemicals , however, an array of variants are made from renewable materials such as polylactic acid from corn or cellulosics from cotton linters. Plastic can be divided into two major categories Thermosetting and Thermoplastic. They are formed from polymers, the word “poly” means many & “mers” means monomers simply many monomers. Plastic are formed by polymerization. Most common types of synthetic organic © 2020, IRJET

polymers are Low-Density Polyethylene (LDPE), High Density Polyethylene (HDPE), Polyvinyl Chloride (PVC), Polypropylene (PP), Polystyrene (PS), and Polyethylene Terephthalate (PET or PETE). The Benefits of plastic are undeniable. The material is cheap, lightweight and easy to make. These qualities have led to a boom in the production of plastic over the past century. The quantity of plastic waste is expanding rapidly which is a great threat for the environment. Worldwide, about 50 kg of plastic is produced annually per person, with production doubling every ten years. In 2018, a survey by the Global Oceanic Environmental Survey (GOES) Foundation found that the ecosystem in seas and oceans may collapse in the next 25 years, potentially causing failure of terrestrial ecosystem and "very possibly the end of life on Earth”. The main agents of this prediction were hypothesized to be plastic. According to recent estimates 79% of the plastic waste ever produced now sits in landfills dumps or in the environment while 12% has been incinerates and only 9% has been recycled. When discarded in landfills or in the environment, plastic can take up to a thousand years to decompose.
2. AIM AND OBJECTIVES
To develop an efficient way to effectively utilize the HDPE wastes plastic for construction materials.
To reuse waste plastic for reduce of land and water pollution.
To reduce the consumption of clay for manufacturing of bricks that results in resource depletion and environment degradation.
3. MATERIAL AND METHODOLIGY 3.1 Material 3.11 HDPE Waste Plastic HDPE is known for its high strength-to-density ratio. The density of HDPE can range from 930 to 970 kg/m3. It has strong intermolecular forces and tensile strength than LDPE. It is also harder and more opaque and can withstand somewhat higher temperature (120°C) for short periods. In manufacturing plastic sand bricks, hard waste plastics like bottles caps, older ice-cube trays, fruits & bottles crates, stools, chairs, pipes, jugs, barrels, water-tank, toys, dustbins, buckets, etc were used. These waste plastic were shredded using plastic shredder machine and then used in manufacturing plastic sand bricks.
