Optimal proportional combinations of rubber crumbs and steel slag for enhanced concrete split tensile strength

ABSTRACT

Waste management is one of the essential issues in the global domain of environmental conservation. The flourishing promotion of the Automobile Industry in India has eventually ended up with an increase in dumped waste material, such as a waste tyre. Steel slag was also added to the improvised concrete mix (CRAC) in a frozen percentage within the cement mantle of the concrete matrix for the stabilization of the binding qualities. It was discovered that an optimal proportional combination of 12% waste rubber tyre crumbs and 9% steel slag proved to be the most techno-economically viable solution for maintaining the mandated qualities of supplied 30MPa or other base values for concrete with reference to a specific purpose due to calcium oxides. The achieved split tensile strength (3.762MPa) validated this ideal proportionate combination as the best and most long-lasting.
