It is estimated that 1.2 billion of waste tyre rubber produced globally per year. Tyres tend to re-emerge in time from the dump and micro-organisms may take more than 80 years to biodegrade them. In this context, our present study aims to investigate the optimal use of waste tyre rubber. This research paper explores a detailed study of compressive strength of concrete by using waste tyre rubber as percentage replacement of coarse aggregate. Conventional mix M-25 and M-30 are designed as per IS 10262:2009. The waste tyre rubber is chipped according to specified shape so as to ideally replace coarse aggregate (2.5% & 5%). Total 54 concrete cube specimens were casted including specimen with and without replacement of coarse aggregate.The compressive strength test were conducted after 7days, 14 days and 28 days of curing. The replacement of coarse aggregate was effective and compressive strength was increasing in the case of 2.5% replacement in both mix (M-25 and M-30). The use of waste tyre rubber in the concrete results into benefits of better disposal of waste rubber and also increased the characteristics strength of concrete.

INTRODUCTION An estimated 1000 million tyres reach the end of their useful lives every year. At present enormous quantities of tyres are already land filled. Tyre land filling is responsible for a serious ecological threat. Mainly waste tyres disposal areas contribute to the reduction of biodiversity also the tyres hold toxic and soluble components. Secondly although waste tyres are difficult to ignite, this risk is always present. Once tyres start to burn down due to accidental cause’s high temperature take place and toxic fumes are generated besides the high temperature causes tyres to melt, thus producing oil that will contaminate soil and water. Millions of tyres are just being buried all over the world. Tyre rubber wastes are already used for paving purposes; however, it can only recycle a part of these wastes. Some research has already been conducted on the use of waste tyre as aggregate replacement in concrete showing that a concrete with enhanced toughness and sound insulation properties can be achieved. Rubber aggregates are obtained from waste tyres using two different technologies mechanical grinding at ambient temperature and cryogenic grinding at a temperature below the glass transition temperature. II. OBJECTIVE The objectives of this study are: 1) An alternative way of recycling rubber by incorporating them into concrete construction. 2) To introduce an eco-friendly technology by incorporating rubber into concrete, which can benefit the society and the nation. 3) To study effect of rubber on compressive strength of concrete.
