Experimental study on partial replacement of fine aggregate in concrete by waste tyre rubber and cement by fly ash

Abstract

Waste tyre disposal is one of the biggest environmental problems the world is currently experiencing. Because of its non-bio degradable character, it is very difficult to dispose them without making much harm to the environment. So, there is a big need of finding out a new way to dispose the tyre waste safely. Use of tyre rubber in place of fine aggregate in construction field was one of the alternatives put forth. An investigation in the compressive strength of concrete having shredded tyres in place of sand was conducted through an experimental program. For this investigation, several cubes, beams, and cylinders of M30 grade were cast. The fine aggregate in concreter mix were replaced with 20%,25%,30% of tyre rubber. As we all know that, that, there are numerous thermal power plants across the world, each plant produces different kinds of waste materials like fly ash, its disposal also needs some serious supervision. Due to the presence of some chemical’s like calcium oxide, fly ash can be used as a cementing material. This experiment studies the characteristics of tyre rubber induced concrete and check the feasibility of replacing cement with 25% of fly ash in that rubberized concrete mix.
