MECHANICAL PROPERTIES OF CONCRETE BY ADDING PLASTIC AS A PARTIAL SUBSTITUTE FOR COARSE AGGREGATE TO PROMOTE SUSTAINABILITY ON CONSTRUCTION INDUSTRY

Concrete is without a doubt the most advantageous material in the building industry, but every coin has two sides. Raw materials used in the manufacturing of concrete, in one way or another, have a negative impact on the environment. For instance, as cement is produced, dust is released into the atmosphere during the production of aggregates. The area's geology is further impacted by the production of coarse aggregates. The use of waste materials in addition to or in place of cement is a step in this direction. Many of these substances, like silica fume and rice husk, are currently in use. In this investigation, synthetic coarse aggregates are employed in place of natural coarse aggregates. Plastic aggregates were only little treated from plastic waste. Plastic is currently the largest environmental problem, and it is becoming worse quickly. According to certain recent research, it can be used in the construction industry because of several of its traits, such inert behaviour and resistance to degradation. Utilising leftover plastic can help reduce the amount of plastic in the trash stream. Using plastic coarse particles, many tests were conducted to examine the mechanical properties of concrete. Concrete was made using plastic coarse aggregates with a variety of plastic compositions. Plastic coarse aggregates at varied concentrations of 0%, 2.5%, 5.0%, 7.5%, 10.0%, and 12.5% were used to make concrete.
