Abstract

In our world, products are used and then discarded. Even when materials are recycled, the remaining refuse can create an environmental concern. More production equals more waste, more waste creates environmental concerns of toxic threat. Motivated by the tremendous trend toward green environment and to reduce the effect of scrap tires on the environment, this research is an attempt to find a practical and environmentally sound solution of the problem of scrap tires. An economical viable solution to this problem should include utilization of waste materials for new products and one that minimizes the heavy burden on the nation�s landfills. Partially replacing concrete aggregates with recycled materials could help to combat the decreasing availability of some natural resources (natural sand) and at the same time help to utilize growing quantities of waste material like used tyres. This idea has been put into practice to develop a more sustainable concrete material called rubberized concrete or crumbed rubber concrete (CRC). An experimental investigation is done to enhance the strength of rubber concrete where the rubber obtained from recycling scrap tires are used in the form of crumb rubber as a replacement of fine aggregate & in the form of rubber chips as a replacement of coarse aggregate. The specimens are tested for their workability to determine the strength of Rubberised concrete also Water absorption and specific gravity of rubberized concrete. From previous studies made, it is seen that the compressive strength of rubberized concrete is very less when compared to that of conventional. Therefore, with the help of admixtures both the Chemical & Mineral admixtures, using various blends the strength of rubberized concrete is enhanced. Management of waste-tire rubber is very difficult for municipalities to handle because the waste rubber is not easily biodegradable even after long-period of landfill treatment. However, the waste tire rubber is a promising material in the construction industry due to its lightweight, energy- absorption, erosion control, sound and heat insulating properties. The purposes of this study investigate the mechanical behaviour of concrete with chipped waste tire material. A replacement of chipped rubber as coarse aggregate .A control ordinary Portland cement mix is designed using Indian Standards methods and the chipped rubber content of 25,50,75 &100% as replacement of coarse aggregate. The compressive strength of rubberized concrete were investigated experimentally in this project at 3,7 and 28-days
