“APPLY WASTE TYRE RUBBER IN A PARTIAL REPLACEMENT OF AGGREGATE IN CONCRETE”

CIVIL ENGINEERING

The waste problem considered as one of the most crucial problems facing the world as a source of the environmental pollution. During last recent years, many improvement in India have occurred in all parts of life such as social, industrial, economical etc., this will lead to generate new ways of living and increase the human requirements, and will also increase types and quantities of the waste in India, without any active processes to provide solution to this problem. Waste rubber tires cause serious environmental problems all over the world. One of the potential means of utilizing the waste tires is to process this waste material for the protection of the environment and society. It is suggested to use this waste tires as an additive in portland cement concrete mixes, which would partially help in solving this problem. India manufacture 11.92 Crore tires in year 2010 – 11 increase by 22.72% than year 2009 – 10 (ATMA – Automotive Tire Manufacturer Association). With the exponential growth in number of automobiles in India during recent years, the demand of tires as original equipment and as replacement has also increased. The quantity of scrap tires produced in India is not exactly available but the increasing trend of use of road transportation will definitely create a problem of disposal in very near future. The total number of registered buses, trucks, cars/jeeps/taxis and two wheelers up to 1997 in India were 0.5 million, 2.25 million, 4.7 million and 26 million, respectively. Considering the average life of the tires used in these vehicles as 10 years after rethreading twice, the total number of waste disposable tires will be in the order of 112 million per year. That’s why this is one of the most crucial environmental issues all around the world is the disposal of the waste materials.
