  • Abstract:
  • Aggregates are inert granular materials that are essential ingredients in a concrete. Aggregates occupy a large volume (i.e.) about 60 to 75% of the concrete, thus the selection of aggregates based on the material, shape, gradation and size is of primary concern before preparing the concrete. However many developing countries like our country face problem in acquiring the aggregates, as they are the most exploited material for the purpose of construction. And this over exploitation has led to scarcity in the availability of aggregates from the natural sources, in many parts of our country. Therefore, in order to meet the demand for aggregates, a modification be can made as partial or complete replacement of these aggregates with any new material, that would potentially induce better and additional properties to the concrete and simultaneously serve as an economical resource. With the Phenomenal growth in the Automobile industry in our country, there are so many waste and used tyres, those are getting discarded every year (i.e.) about 3 crores of used tyres are disposed in our environment. When these tyres are granulated or made into fine powder, they can be effectively used as crumb rubber. This study investigates the use of crumb rubber fragments and crumb rubber fine powder (each material of quantity of about 2%, 4%, 6% and 8%) as a partial replacement of both coarse aggregates and fine aggregates respectively. To evaluate these replacements in the OPC concrete mix, a number of laboratory tests were carried out. The tests those were conducted on the hardened concrete includes the compressive strength test, flexural strength test and Split tensile strength test on the 3rd , 7th and 28th days of curing. Finally, the results of all the above mentioned tests were compared with the conventional concrete to find the potential and the scope of this concrete modified with crumb rubber. This result shows there will be an increase in characteristic of concrete.
