Abstract- Recycling used tyres is a very laborious process, which makes the disposal of discarded tyres a contemporary problem that poses a threat to public health. One of the most effective ways to recycle old tyres is to use them in the construction industry as a partial replacement for Portland cement. The purpose of this research is to determine the slump, compressive strength, splitting tensile strength, and water absorption of concrete made with rubber tyre (RT) and Calcined clay (CC) as partial substitutes for 30 percent of the cement. The purpose of this study is to determine the ideal ratio of reclaimed and recycled materials (RT and CC) to use in concrete mix in order to achieve the highest possible level of strength while simultaneously achieving the lowest possible level of water absorption (WA). In order to achieve this goal, numerous concrete mixtures, each with a unique combination of RT and CC in its make-up, have been produced. A mixture of RT and CC in varying proportions has been used to replace thirty percent of the weight of the cement. The findings suggest that the combined use of RT and CC in concrete improves the mechanical characteristics while simultaneously reducing cement consumption. This can help to lessen the negative environmental implications of cement manufacturing and helps to bring about a more sustainable environment.
