Rubber chips, Crumb Rubber, Replacement, and Rubber Concrete.
In our world, products are used and then discarded. Even when materials are recycled, the remaining refuse can create an environmental concern. An economically viable solution to this problem should include utilization of waste materials, partially replacing concrete aggregates with recycled materials that 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 tires. This idea has been put into practice to develop a more sustainable concrete material called rubberized concrete or crumbed rubber concrete (CRC). Experimental studies are done using the waste tire rubber in concrete in the form of crumb rubber as a replacement of fine aggregate & in the form of rubber chips as a replacement of coarse aggregate. From the literature study, the replacement percentage of fine and coarse aggregate with crumb rubber and rubber chips is identified as 25%, 50%, and 75%.A High range water reducer is used as super plasticizers for all the mixes. These specimens are tested for 7 & 28days to determine their strength parameters by conducting compressive strength test, split tensile strength, flexural strength and nondestructive tests such as Rebound hammer & Ultrasonic pulse velocity. From the detailed study conducted, it was concluded that the compressive strength was found to decrease with the increase in the percentage of rubber. The structural application of rubber concrete is very less but can be used in pavements to have better skid resistance, rutting resistance and improved fatigue cracking resistance.
