Abstract: The tire out of use is an abundant material that is not easily biodegradable. Despite of the high
index of retreading, most of them are disposed in inadequately. Another problem also related
with its disposal is the burning of this material that liberates toxic gases and pollutes the
environment.
The objective of this work is to offer a clean alternative of final destination for the tire out of
use. And also show the influence of the rubber's surface treatment with saturated sodium
hydroxide aqueous solution in mechanical properties of mortars that contain this material. The
influence of the treatment was determined by the comparison of mechanical tests' results in
specimens that contained treated and untreated rubber. The analyzed properties were:
compressive strength, tensile strength, modulus of elasticity and water absorption. Most of the
tests were carried through the ages of 7, 28 and 56 days.
The results indicated that the treatment of the rubber's surface influences in some properties
of mortars added with tire rubber particles.
