Abstract - This study describes the effect of tire rubber crumb on concrete. This research helps to understand the use and effect of rubber tire crumb in concrete structures. Improving the recycling of waste materials in accordance with the principle of sustainable development. The procedures used in this research used experiments such as, slump cone test, water absorption test etc. Disposal of waste tire rubber has become a major environmental problem in all parts of the world which poses a very serious threat to the environment. So far only a small fraction is recycled and millions of tires are simply stockpiled, landfilled, or buried. This paper reviews tests conducted using rubber tire waste concrete samples to determine compressive strength. It was found that the compressive strength rubberized concrete was lower than the control mixture, while it exhibited better results in abrasion resistance. Fine aggregates are partially replaced by crumb rubber to form crumb rubber concrete. Finally, crumb rubber was introduced into the concrete mixture after pre-treatment by six modifiers.
Key Words: Crumb Rubber, Aggregates, Compressive strength, Water, Concrete.
1.INTRODUCTION
India accounts for 6-7% of global total waste tires. As the local tire industry is growing at a rate of 12% annually, the volumeofwastetiresisincreasing.Morethan1billiontires are manufactured worldwide every year and the same number of tires from waste vehicles are removed permanently. The US is the largest producer of waste tires, about 290 million a year. In China and India, the volume of tire waste is increasing at a high rate due to the rapid increaseinthesalesofnewvehicles.Sincetiresaremadeto last longer, the same things that make them durable also make them difficult to dispose of which has a long-term impact on the environment. India produced 90000 MT of reclaimed rubber from waste tires in 2011. It takes thousandsofyearsforatiretocompletelydecomposealone. In many cases it burns, releasing toxins and pollutants into the air, water, and soil. Stockpiling or illegal dumping or landfilling are traditional methods of disposing of waste tires,buttheseareshort-termsolutions. Recyclingofvehicle tires is essential as disposing of waste tires is not an easy task Tires are among the largest and most problematic sources of waste, due to mass production and their durabilityTiresareamongthelargestandmostproblematic sourcesofwaste.
2. METHODOLOGY
1.1 Materials Used
1 Cement: Ordinary Portland cement, 43 grade confirming IS 12269-1993. The compressive strength measured in the standard mortar at 28 days was 24 MPa.
2 Coarse Aggregate: The aggregates which is retained overISSieve4.75mmistermedascoarseaggregate.
3 Fine Aggregate: The aggregate passing from 4.75 mm andretainedon75µmmISsieve.

4 Water: Potable water is used which is Free from silts, salts and shall fulfill the requirement as per IS 456:2000.
5 Tire Rubber Crumb: Crumb rubbers are obtained by grinding. Recycled Tire Crumb particle size ranging in from4.75mmto0.075mm.
3. RESULT AND DISCUSSION
The specimen for the compressive strength of concrete test were cured for 7, 14, and 28 days. The result shows thatcrumbedrubbergenerallydecreasethecompressive strength.
1.2 Details of Mix Proportion
1. The concrete mixes are prepared to achieve target strengthof25N/mm2
2. The specimens cubical in shape shall be 15 X 15 X 15cm.
3. The blocks were kept in normal curing condition for7days,14days,and28daysinwater.

3. CONCLUSIONS
Based on the results obtained from the experiment, the followingconclusionscouldbedrawn:
With increasing quantity of the crumb rubber, the compressive strength tends to decrease. A maximum of 88% strength is observed for the mix with 5% replacementofcrumbrubber.
With increasing quantity of the crumb rubber, the compressive strength tends to decrease. A maximum of 64% strength is observed for the mix with 10% replacementofcrumbrubber.
