An experimental study had made on waste product and utilizing it for manufacturing of concrete. The disposal of waste tires is becoming a major waste management problem in the world at the moment. The results of an experimental investigation to study the effects of partial replacement of cement with flay ash in rubberized concrete. The percentage of rubber used in this study was 5% replaced with coarse aggregate and fly ash varies from 0-20% were replaced with cement in conventional concrete. One size of tire rubber chips are used of about 10mm.The mix design was targeted to be M35 grade of concrete. The mix proportion of concrete was 1:1.8:2.41 with water cement ratio of 0.45.The fresh and hardened properties of rubberized concrete produced at three different replacements ratios of fly ash compared to the conventional concrete without rubber and fly ash. A total of 85 cubes, cylinders and beam specimens were cast with the replacement of cement by fly ash with the proportion of 10, 15, and 20% and coarse aggregate by waste tyre rubber with the proportion of 5%by weight and compared with 21conventional specimens. The test result indicates that there was a small reduction in the strength with the 5% replacement in rubber content as compared with the conventional concrete. However, the increase of fly ash from 10% to 15% to 20% improved the mechanical properties of rubberized concrete. Finally it will suggest 20% replacement of fly ash with cement and 5% of waste tyre rubber with coarse aggregate will gives optimal and safest replacement in concrete composites.
