Rubberized concrete under confinement

Waste tire disposal is becoming a significant environmental concern due to lack of landfill space. Tire stockpiles reduce biodiversity and
contain soluble toxic chemicals, which cause several environmental problems. Recently, significant attention has been placed to the use
of rubber in concrete to produce rubberized concrete. This study presents a part of an experimental study conducted to understand the
axial compressive behaviour of rubberized concrete under active confinement. Influences of the addition of different percentages of rubber
and different levels of confining pressure on the compressive behaviour of concrete were examined. Results show that the rubberized
concrete develops lower compressive strength but higher axial and lateral deformation capacities than those of the conventional concrete.
The results also show that confining rubberized concrete improves its compressive strength and axial deformation capacity significantly.
Findings of this study are highly promising for structural applications of confined rubberized concrete.
