ABSTRACT The utilisation of various resources, specifically industrial wastes, in the manufacturing of concrete is the main emphasis of today’s knowledge of concrete technology. One of the key concerns in the global protection of the environment is waste management. The growing growth of the Indian automobile industry has ultimately led to a rise in the garbage that is dumped, such as used tyres. Coal ash 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. For sustaining the required qualities of supplied 30 MPa or other base values for concrete with reference to a specific purpose, it was found that an optimal proportional combination of 12% waste rubber tyre crumbs and 9% coal ash was the most technologically and economically effective solution. Flexural strength of 5.18 MPa, which was attained, confirmed that this optimum proportionate combination was the best and most durable.

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.
