Concrete Reinforcement Advantages of Welded Wire Fabric |
| Higher
characteristic Design Strength WWF with Fe480
grade results in savings in steel area or steel
weight required to the tune of 13.55% vis-a-vis
HYSD bars of Fe415 grade and to the tune of 47.925
vis-a-vis Plain Mild Steel bars of Fe 250 grade.
|
Vastly Superior Bonding Behavior
As against the peripheral surface area which is
responsible for bonding to concrete in the case of
individual bars, the right mechanical
interconnections by means of welds to cross wires
are primarily responsible for stress transfer from
concrete to steel and vice-versa in the case of
WWF. Each of the rigid welds capable of resisting
upto 210 N/mm2 ensure quick and complete stress
transfer within 2 welded joints from the critical
section. |

Better and Economic Crack Resistance with Thinner
Wires and Closer Spacings
WWF usage affords the possibility of using thinner
wires at closer spacings. This serves most
effectively in countering the non-load phenomena
or strain induced stresses due to Shrinkage and
Temperature changes. The close spacing of thinner
wires and the two way behavior of WWF minimizes
the crack widths and preserves structural
integrity of the slab. |

Savings of Labour,
Time and Binding Wire
The most obvious and clinching advantage in the
use of WWF is the immediate and positive savings
in labour and time. It is complete freedom from
all the mundane filter's jobs. There is no cutting
of bars, no marking and spacing them out, and
above all no laborious tying of binding wires |

The only feasible
and Essential Reinforcement for ground slabs WWF
usage provides the only practical and easy
solution for reinforcing slabs on ground.A plain
concrete slab under construction of sub-soil
erosion or movements or due to temperature changes
coupled with heavy traffic loading will develop
cracks which collapse concrete of the surface. The
tendency to use extra high strength concrete or
extra thickness of concrete to minimize cracking
does not solve any problems since the strains
induced by the drying shrinkage or temperature
contraction do not appreciably change with
thickness. Cost of a WWF reinforced slab is also
more or less similar to that of a slightly thicker
unreinforced slab. Usage of WWF serves to control
cracking and crack width in both directions. It
ensures that even if a crack develops the cracked
faces are held together and the aggregrate
interlock is maintained. |

Flexibility of
Handling and Placing
The usage of thinner wire lends the fabric as extremely
flexible in handling. Coupled with the availability in
long lengths in roll form, WWF provides the ideal and
convenient solution for all kinds of repair work by
Re-plastering orr Guniting.
The
same aspect makes WWF indispensable in thin elements
such as Precast partitions, shelves, fins, ferrocements
or ferrocate products such as ferrocate water tanks etc.
WWF is the only solution for the thin and tough spine of
thin and efficient structural elements such as folded
plate roofs, folded plate precast roof girders or
hyperbolic paraboloid shells |
