Steel Fiber Reinforced Concrete (SFRC) is a composite material consisting of steel fibers and cement-based matrix.This type of concrete has higher tensile strength, flexural strength and fatigue resistance than traditional concrete. It is also more resistant to cracking, spalling and impact damage. SFRC can be used in a variety of applications...

The basic shape of corrugated steel fibers is similar to that of shear products, but the tensile strength of single fibers has been greatly improved, reaching more than 1100 Mpa, which is suitable for key projects and large areas of concrete crack resistance parts. Today, the corrugated steel fiber manufacturer, Lo...

Steel Fibre Reinforced Concrete (SFRC) gives concrete its highperformance because the steel fibers are homogeneously distributed. Thus,contributing to considerable increase in load-bearing capacity, high durabilityand high impact resistance, and all this ensures a longer lifetime with lowmaintenance cost. Apart fro...

Steel fiber reinforced concrete pavement is a kind of cement concrete pavement. The pavement is paved with concrete mixed with a certain amount of dispersive short steel fibers. The tensile strength of steel fiber reinforced concrete is much higher than that of plain concrete, and its compressive strength, fatigue ...

Steel fiber concrete compresses the construction schedule, allows for alternative construction methods or design solutions and increases durability. When a project is delivered quicker with fewer efforts and labor, the higher costs of the steel fibers are overcompensated by the savings.In certain applications the volume weight of steelfibers is lower as the rebar for a similar reinforcing effect. ...

Mechanically anchored steel fibers have been proven as reinforcement, even for structural application. Steel fibers are made from a material with well known engineering properties; e modulus, Poisson’s ratio, tensile strength and creep. the e-modulus of steel is greater than that of concrete. thus, the steel fibers pick up the stresses quickly and affect the cracking process immediately. the long ...

Not more than concrete.

The residual flexural strength is equal to the post crack flexural strength of steel fiber concrete corresponding to a certain deflection in a beam bending test. it is a value from testing which has been introduced for the design of steel fiber concrete.

The residual flexural strength is equal to the post crack flexural strength of steel fiber concrete corresponding to a certain deflection in a beam bending test. it is a value from testing which has been introduced for the design of steel fiber concrete.

The post crack strength of steel fiber concrete is a material property which is commonly used to differentiate fiber performance. this will typically be determined with a bending test and is often referred to as the residual flexural strength (see below). For the same concrete composition, steel fiber performance is a function of fiber length, diameter, aspect ratio, anchorage and tensile strength...

No, with good jobsite safety practices in place steel fibers shall not impose any safety concerns. Please refer to our safety data sheets for further information.

Typical steel fiber reinforced concrete contains less than 0.5% vol. steel fibers and hardly more than 0.75% vol. those fibers are discontinuous and not connected to each other. tests only show a slight decrease in electrical resistivity due to the addition of steel fibers. However, the resistance to current flow is still substantial. effects from moisture content and aggregate composition are muc...

No failures of the plastic liner due to fiber punctures have ever been identified. the abrasion from sharp aggregates during placement of the concrete poses just as big of a threat to the liner as do the steel fibers. After placement the fibers tend to move around and re-orient themselves during vibration which relieves any pressure of an individual fiber on the liner created during placement. Man...

For cast insitu, internal vibration is the most used option to consolidate the concrete. Form vibration is generally used in the precast industry.When steel fiber concrete is cast into form work a small amount of vibration of the forms helps keep the fibers from touching the forms and thereby from being visible when the forms are removed. For example, during casting of steel fiber reinforced preca...

Fibers can only protrude from forms where there is a joint. they can not protrude in the middle of a form. this can be minimized if the joints are caulked before concrete placement. However, it is not always possible to calk every joint. the number of protruding fibers is a function of the precision of the joints and the fiber dosage.Wider joints will catch more fibers than tighter joints. After t...

For indoor applications such as tunnels and warehouses, no. For outdoor applications such as pavements some minor rusting may occur. experience in highways and industrial pavements indicate that while individual fibers corrode at the surface, staining of the concrete surface does not occur. overall aesthetics and serviceability are maintained even with the presence of individual fiber corrosion. i...

Yes, but expect a 0.4” to 1.2” slump loss through the hose depending on the steel fiber dose rate, ambient temperatures and hose length. A midrange water reducing agent (MrWr) is commonly used to enhance workability and ease of flow through pump lines. High-range water reducers (HrWr) may be required in some cases. typically, a 4” diameter hose is required.

Yes, the addition of steel fibers at typical dosage rates of 25 to 65 lb/yd3 will reduce the apparent slump by 1” to 3”. However, this does not necessarily equal a reduction in workability. Use of vibratory consolidation, restores the workability to the Steel Fibre Reinforced Concrete (SFRC)

Yes, the addition of steel fibers at typical dosage rates of 25 to 65 lb/yd3 will reduce the apparent slump by 1” to 3”. However, this does not necessarily equal a reduction in workability. Use of vibratory consolidation, restores the workability to the SFrc.

Steel fiber mix designs are similar to those commonly used for plain concrete mixes. recommended aggregate gradations and mix proportions are provided in local standards. Using the largest practical top size aggregate and a well-graded combined aggregate blend as opposed to a gap-graded blend can minimize shrinkage. Steel fibers may cause a reduction in slump due to their stiffness. this does not ...

A properly designed concrete mix is essential for avoiding fiber balling. in order to avoid the potential for fiber balling related to fibers with a high l/d (aspect) ratio (meaning high performing fibers), glued fiber technology has been developed. Glued fiber bundles will spread the glued bundles evenly on “macro level” and during mixing the bundles separate into individual fibers. in essence th...

Steel fibers can be used in concrete, mortar and grout. Generally harsh mixtures, containing very few amount of fines and/or an unsteady sieve curve at a higher fiber volume can create mixing and dispersion problems. Simply mixing steel fibers into any concrete will most probably not utilize all the positive effects fibers can provide to concrete. depending on the type and amount of fibers adjustm...

Yes, also adding fibers on site to the truck mixer is feasible. Gradually dose fibers in the mix, this is typically done via a conveyor belt.

Bekaert recommends continuing mixing at the highest drum speed for about 4 to 5 minutes after all steel fibers are added to the truck.

Yes. introduce steel fibers after all other ingredients are already in the truck. Set the truck mixer on charging speed and add the fibers slowly into the mixer. Mix for about 5 minutes at charging speed.The steel fibers can also be added to the aggregate batch belt, if there is safe access.

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.A variety of fiber types (materia...

The primary advantages of fibre-reinforced shotcrete are:Addition of steel fibers into the concrete improves the crack resistance (or ductility) capacity of the concrete. Traditional rebars are generally used to improve the tensile strength of the concrete in a particular direction, whereas steel fibers are useful for multidirectional reinforcement. This is one of the reasons why steel fiber reinf...

Unshaped (monolithic refractories)[edit]These are without definite form and are only given shape upon application. These types are better known as monolithic refractories. The common examples are plastic masses, Ramming masses, castables, gunning masses, fettling mix, mortars etc.Dry vibration linings often used in Induction furnace linings are also monolithic, and sold and transported as a dry po...
