Abstract:
Concrete is the second most used substance in the world after water and is
the most widely used building material. Its usage worldwide, ton for ton, is
twice that of steel, wood, plastics, and aluminium combined. Concrete is the
primary structural component, that exists in buildings, roads, dams and
bridges. In recent days the problem faced by the construction industry is
acute shortage of raw materials and recycle materials are widely in use for
saving materials for future and similarly recycling the old material.
Used old tires of different vehicles are dumped as it become useless after its
life and became hazardous for environment if used only for burning. Now it
has become necessary to use damaged tires from various vehicles to produce
rubberized concrete structures as a good solution to treat environmental
pollution and reduce the total cost of construction. Rubberized concrete is
used by many researchers by replacing percentages of fine and coarse
aggregate but bonding between rubber and other constituent materials of
concrete remains questionable vis-à-vis effect of temperature on rubberized
concrete.
For addressing bonding of rubber and use it as a replacement of sand is
analyzed for its flexural behavior after treatment of rubber with Waste
Quarry Dust (WQD) with varying temperature. Replacement of sand was
done with non-treated rubber and treated rubber with WQD with
replacement percentages 0%, 5%, 10%, 15%, 20%, and 25%. Flexural test
was performed on Concrete prism beams of size 100mm x 100mm x 400mm
after 28 days curing using center point loading technique after varying
temperatures of 23 ̊C, 200 ̊C, 400 ̊C and 600 ̊C. Flexural behavior of
concrete is analyzed with replacement of sand with rubber (both untreated
and treated with WQD) and effect of temperature on it.
