Experimental Study on Strength Behavior of Concrete with Partial Replacement of Cement with Silica Fume and Coarse Aggregates with Tyre Rubber

Abstract

Rubber tire trash is produced in enormous quantities every year all around the world. Since they are non-biodegradable by nature, recycling them is difficult. They emit smoke that is extremely poisonous and dangerous. Therefore, the only choice is to dispose of them in landfills. It is also not a good answer because it consumes a lot of area and waste rubber stocks pollute the soil and groundwater in addition to contaminating water bodies. Statistics reveal that more than 500 million tires are dumped in landfills each year, and it is predicted that by 2030, around 5000 million tires would be dumped. The utilization of old rubber tires in concrete has been demonstrated by several investigations. Concrete and rubber tires have demonstrated. Although the compressive and flexural tensile strengths of concrete reinforced with rubber tires have decreased, they do offer certain advantages, including improved toughness, impact resistance, thermal characteristics, and acoustic qualities.

The primary goals of this study are to explore the strength characteristics of M30 grade concrete using rubber tyre aggregates (RTA) and silica fume in place of cement. The percentage of silica fume and rubber tyre used as 0%SF+0%RT, 5%SF+10%RTA,10%SF+20%RTA,15%SF+30%RTA,20%SF+40%RTA.
