New Generation Rubberised Concrete & its Basic Engineering Properties

The disposal of used tyres is becoming a major waste disposal problem throughout the world. The accumulation of used tyres is an environment threat. One such effective way of disposing the used tyres is by reusing them in construction industry in an environmentally friendly manner.This research focuses on determining, first the correct proportion of the tyre fibers that has to be added to the concrete mix design to get the optimum properties of the concrete and second in fixing up the exact dimensions of the tyre fiber that is most suitable for the concrete mix because the length of the fiber, the diameter of the holes and the number of holes in them play an important role in determining the properties of the concrete like toughness, durability and deformation. Based on the above, a New Generation Rubberized Concrete (NGRC) was proposed.The experimental research have proven that NGRC and E-NGRC have significant capabilities in resisting crack propagation, environmental abrasions, resistivity to high impact resistance, high flexural strength, withstanding high loads and vibrations and exhibiting good elastic nature and have many potential applications in the construction industry.
