Abstract
The use of plastic has grown extensively in recent years all over the world. It is inexpensive and easily available and can be moulded into any shape. However, plastic is nonbiodegradable; it causes pollution and create difficulties in managing even for a wealthy nation. The purpose of this study was to investigate the environment‐friendly potential use of plastic and demonstrate usefulness of plastic sand bricks as alternative structural elements, replacing standard clay brick. The physical and mechanical properties of plastic sand bricks were studied in different plastic sand ratios of 1 : 3, 1 : 4, and 1 : 5 by their weight, using plastic as a binder. Moreover, the thermal resistance test, split tensile strength test, penetration test, and Fourier transform infrared spectroscopy were performed. The study concluded that the strength of plastic sand brick depends upon the uniformity of the mixture and increases when the ratio of sand and plastic in the mixture is increased to 1 : 4 from 1 : 3. Any increase or decrease in the ratio 1 : 4 is found to reduce the strength. All the bricks in any of the ratios showed zero water absorption and nil efflorescence.
Highlights
A petrochemical derivative introduced in 1907, is a life-changing resource. It is made up of a variety of synthetic or semisynthetic organic compounds with a high molecular mass, as well as other malleable substances that can be moulded into solid things. ey are manufactured by polymerizing or polycondensing natural materials such as cellulose, coal, natural gas, salt, crude oil, minerals, and plants
Based on the experimental study of plastic sand brick, it is concluded that the proportions of plastic and sand, as well as the uniformity of mixture, impact the compressive and split tensile strength of plastic sand brick
E compressive and split tensile strength increases with a reduction in the percentage of plastic from 25% to 20%
Summary
A petrochemical derivative introduced in 1907, is a life-changing resource. It is made up of a variety of synthetic or semisynthetic organic compounds with a high molecular mass, as well as other malleable substances that can be moulded into solid things. It is a versatile material that can be used in several different ways. Durability, flexibility, variety, and cost, plastic has proven to have a great advantage over other materials such as wood, natural fibers like cotton and wool, rubber, and paper. Made on a large scale, it is the cheapest material available on the market [1]. It is a material that people do not utilize correctly [3, 4]
