Experimental Investigation of Waste Rubber Admixtures in Concrete
Abdullah F. Ahmed
Abstract
In this experimental study, coarse aggregate is partially substituted with tyre rubber to examine the behavior and failure properties of rubberized concrete. Due to this waste's inability to biodegrade, there are significant fire, environmental, and health dangers. Concrete's characteristics could be greatly improved by using used tire rubber as a partial aggregate in a variety of ways. Currently, one of the world's biggest waste management issues is how to get rid of used tires. About 1.2 billion trash tires are produced annually worldwide. Therefore, efforts have been made to determine how discarded tires might be applied in construction projects. The purpose of this research is to look into the best way to use used rubber tires into concrete mix as coarse aggregate. Concrete is made by substituting 20%, 30%, and 40% of coarse aggregate with tires and the outcomes are compared to those of standard M25 grade concrete. The durability of newly laid and cured concrete were determined. The findings showed that rubberized concrete can be used to successfully counteract a loss of strength while maintaining the benefits of greater ductility. This suggests great prospects for uses in seismic zones, notably for structural columns. The main goal of this research is to identify an effective strategy for reusing rubber waste for improved ecological circumstances and the building sector.
