Experimental Investigation of Waste Rubber and Steel Fiber Reinforced Cement Concrete

Waste tire rubber is used due to its light weight and elastic properties and steel fiber for its ductile and flexural toughness. In this study, there are two different mixes. M20 mix in which waste tire rubber was replaced at different replacement levels (0%, 10%, 20%, 30% and 40%) and same replacement for M25 mix keeping 2% steel fiber constant in above mix. Mechanical and durability properties were studied. When we compare the strength of above two mixes M25 mix concrete containing 2% steel fiber shows good results as its compressive, tensile and flexural strength increases compared to M20 mix. When replacement of 10% is done there is nearly 27%, 18%, and 13% rise in compressive, tensile, and flexural strength of rubber concrete with 2% steel fiber.
