Feasibility Analysis of Rubber as Crushed Sand and Fly Ash as Cement

Currently, the disposal of waste tyre is becoming a major waste management problem worldwide. It is estimated that Approximately 1.4 billion tons of waste tire rubber produced globally per year. The present study aims to investigate the optimal use of waste tyre rubber crumbs as a substitute for crushed sand in concrete composites. This study determines the compressive strength performance of rubber concrete and the disposal of waste tyres. Concrete is a mixture of cement, aggregate, water, and admixtures. In concrete, fly is used as a cementitious material. A comparative study is carried out, and the use of fly ash as a cement replacement in concrete can be analyzed and compared. The feasibility analysis aims to assess the practicality and viability of using rubber as crushed sand and fly ash as cement in concrete. Using rubber as crushed sand and fly ash as cement i n concrete has shown promise in several studies. Additionally, incorporating fly ash as a cement replacement in concrete mixtures has been found to improve compressive strength.
