Mechanical Properties of FiberWaste Tire Concrete

Abstract

Abstract:
Many of researchers study the uses of chopped worn-out tires as a replacement
material to production special types of concrete. In presented work, the worn-out tires
were used as fibers which have dimensions of 1×1×3 cm. The fibers used as a partial
replacement from volume of coarse aggregate. Two mixes of fiber worn-out tires
(F.W.T.) concrete in addition to reference mix were selected, using Partial
Replacement Ratio (PRR) of 20% and 30%. The tests which were used in this study
were: compressive strength, splitting tensile strength and flexural strength. It was
found that incorporating of F.W.T. in concrete effected negatively on most properties
of concrete, for example the percentage decreases in compressive strength relative to
reference mix at 28 day were 20% and 27.3% for concrete with 20% and 30% F.W.T.
by volume of coarse aggregate respectively. However, it gave good indicator to be
utilized as a new construction material in many applications.
