Welded Wire Reinforcing, abbreviated WWR or WWF (Welded Wire Fabric), is generally used for reinforcing floor slabs. This type of reinforcing is made from a series of bars that run perpendicular to each other - in a grid layout. The bars are welded together to form a "sheet". The nomenclature for specifying welded wire fabric is: WWR 8 x 6 ...
FIBER REINFORCING IN CONCRETE SLABS, WHAT YOU NEED TO, Mar 20, 2015 0183 32 Fiber reinforcing has no impact on the air content of concrete compared to the same sample of non-fiber concrete, but the impact on slump is significant The use of fiber generally will decrease the same sample by 2 inch In some cases, the use of a high-range water-reducing admixture …
Some specifications for casting of beams are as follows, Beam size taken – 150mm*150mm*700mm. Mix proportion for concrete 1 : 1.5 : 3. Water: cement ratio (by mass) – 0.45. Addition of Steel Fibres – 0.3% of Fibres by total weight of concrete. Figure Casting of cube moulds with concrete.
To put it simply, steel fibers prevent cracks, while rebar limits the width of cracks. Let's consider two examples: a wide-slab floor and a continuously-reinforced concrete highway. Example 1 (above photo) is a warehouse floor 250 feet wide and 500 feet long. Following CFS Wide-slab principles, the concrete contains steel fibers at 70 pcy.
Next level concrete performance. Steel fiber reinforcement has been around since the 1970s and continues to evolve with time. The bents and hooks are crucial to the fiber's anchoring performance and subsequent concrete ductility.These features, in combination with steel elongation, are the main-differentiators of our Dramix® steel fiber concrete reinforcement …

For concrete exposed to weather or earth (such as basement walls) #6 bars and larger: 2 inches. #5 bars or smaller: 1½ inches. Top: Reinforcing steel mats are supported by chairs to keep the steel at the proper elevation in the slab. Bottom: Concrete must be held in the proper position during concrete placement.
Weight of rebar per cubic meter of concrete. Rebar is short form of reinforcing bar or Steel reinforcement, it is steel bar or Steel reinforcement provided as tension bar, used in reinforced concrete structure like footing, foundation, column, beam and slab of house construction and it also used in reinforced masonry structure like retaining wall and load bearing wall.

By reinforcing concrete, however, you can create a material that is much stronger than its components. Steel is particularly well suited as reinforcement because it bonds well to concrete and expands at the same rate. When combined, steel and concrete form a new building material, reinforced concrete.

Steel fibre concrete is a type of reinforced concrete. It's basically made up of cement, water, sand, gravel and steel fibres. In some cases additives are added. Steel fibres are discontinuous and isotropic, short metal reinforcements similar to metal filaments or threads. These can be corrugated, wavy or smooth, with flat or shaped ends.

Steel fiber reinforced concrete is an alternative to traditional reinforced concrete for certain application areas. Steel fibers are a discontinous, 3-dimensionally orientated, isotropic reinforcement, once they are mixed into the concrete.Steel fibers bridge the crack at very small crack openings, transfer stresses and develop post crack strength in the concrete.
The steel fibers are mainly used for reinforcement of concrete, it also provides exceptional control of drying shrinkage cracking and maximum load stability at the floor joints, where it is most needed. Concrete reinforcing Steel Fiber has the following types: Corrugated Steel Fiber material has high tensile strength and cost saving application.

Addition of steel fibers up to 5% by volume increased the flexural strength to about 2.5 times that of plain concrete. As explained above, mixing steel fibers considerably improves the structural properties of concrete, particularly tensile and flexural strength. Ductility and post cracking strength, resistance to fatigue, spalling and wear and ...
Steel fiber reinforced shotcrete improves ductility, fracture toughness and energy absorption capacity. Fiber reinforced shotcrete has many benefits including greater homogene of the support structure, and simpler application logistics. Steel Fibers available in the U.S.A, Canada and Latin America Steel Fibres available in the U.K. Europe and ...
Fiber reinforced concrete is a composite material and therefore, all fibers are tested in the concrete to prove their performance. Fibers begin to function in a structural supportive manner when the concrete matrix starts to crack, just like traditional reinforcement. The crack has to occur for the load to switch from the concrete to the ...
Xorex Fibers comply with ASTM A820 requirements. Typical lengths: 1.0", 1.5" and 2.0" (25, 38mm and 50mm), but also can produce 0.75" and 2.5". Commonly used to improve concrete toughness, shear strength, and impact resistance. Concrete reinforcement fibers reduce concrete cracking due to reduce shrinkage. Typical applications: Dams.
