Concrete
is reinforced to give it additional strength - without such reinforcement, many
building projects would not be possible. Steel
fiber reinforced concrete can be used for various types of structures and
components and can be made into almost any shape or size. The material is
developed by incorporating steel reinforcement bars, plates or fibers into the
traditional concrete mix.
Fibre steel was first used in the mid-1800s by
French building contractor Francois Coignet. His own house, built with
reinforced concrete, still stands some 150 years following construction.
Typically
used for retaining walls, highways, concrete foundations, and sewerage tanks,steel fiber reinforced concrete provides
additional tensile strength for heavy duty construction projects. The steel
reinforcement gives added strength by taking up the tension stresses, while the
concrete takes up the compression stresses; meaning the two materials act
together as resisting forces.
The
coefficient of thermal expansion of concrete is similar to that of steel,
eliminating internal stresses due to differences in thermal expansion or
contraction. In concrete reinforcement, the cement paste hardens and adapts to
the surface details of the steel, meaning that any stress can be effectively
passed between the two materials. Steel bars are often roughened or corrugated
to further enhance the bond between the concrete and steel. Adding alkaline
producing carbonate Calcium causes a film passivatingto form on the surface of
the steel, making it much more resistant to corrosion than it would be in
neutral or acidic conditions.
Precision
Drawell is concrete contractors who
undertake many projects that make use of Fibre for Concrete. Some of the most typical structures include water treatment
works and waste water treatment works as well as highway projects and flooding
and coastal defense schemes. As steel
fiber reinforced concrete contractors, Precision Drawell provides a full
design and build apackage to suit any
project.
