Abstract
The development and utilization of the high strength concrete in the
construction industry have been increasing rapidly. Fiber reinforced
concrete is introduced to overcome the weakness of the conventional
concrete because concrete normally can crack under a low tensile force
and it is known to be brittle. Steel fibre is proved to be the popular and
best combination in the high strength concrete to result the best in the
mechanical and durability properties of high strength concrete with
consideration of curing time, steel fibre geometry, concrete grade and
else more. The incorporation of steel fibre in the mortar mixture is
known as steel fibre reinforced concrete have the potential to produce
improvement in the workability, strength, ductility and the deformation
of high strength concrete. Besides that, steel fibre also increases the
tensile strength of concrete and improves the mechanical properties of
the steel fibre reinforced concrete. The range for any high strength
concrete is between 60MPa-100MPa. Steel fibre reinforced concrete
which contains straight fibres has poorer physical properties than that
containing hooked end stainless steel fibre due to the length and the
hooked steel fibre provide a better effective aspects ratio. Normally,
steel fibre tensile strength is in the range of 1100MPa-1700MPa. Addition
of less steel fibre volumes in the range of 0.5% to 1.0% can produce
better increase in the flexural fatigue strength. The strength can
be increased with addition of steel fibre up to certain percentage. This
paper will review and present some basic properties of steel fibre reinforced
concrete such as mechanical, workability and durability properties.
