Frequently asked Questions


Just as technology plays a vital role, the materials used for shaping modern infrastructure play a vital role too. With a state-of-the-art production unit and cutting-edge production facility, we have the advanced technology to manufacture the highest-quality steel fibre reinforced concrete for high-performance concrete.

Frequently asked Questions

Steel-fibre-reinforced concrete (SFRC) is a form of reinforced concrete used for specific applications. It contains steel fibres that can be arranged three-dimensionally, creating a discontinuous and isotropic reinforcement once mixed into the concrete. Steel fibres can effectively seal off tiny cracks and help transfer stress, ultimately increasing the post-crack strength of concrete structures.

Steel fibres can be used in the composition of concrete, mortar, and grout. However, if these mixtures contain very few fines and/or an unsteady sieve curve at a higher fibre volume, problems such as mixing and dispersing can arise. In order to maximize the benefits of adding steel fibres to concrete, it is necessary to adjust the components of the mixture based on the type and amount of fibre used. Simply mixing steel fibres into any given concrete mix may not be enough.

With any financial product that you buy, it is important that you know you are getting the best advice from a reputable company as often you will have to provide sensitive information online or over the internet.

We recommended that the drum be operated at its highest speed for a period of 4 to 5 minutes after all steel fibres are added to the transport vehicle.

Yes, it is possible to incorporate fibres into the truck mixer at the job site. Fibres should be introduced in batches, which can usually be done with a conveyor belt.

Through examining the compressive strength and tensile strength, it has been determined that the ideal volume fraction of steel fibre to be added to the concrete mix is 1%.

Aspect ratios ranging from 40 to 80 are being utilized at present. It is noteworthy that handling fibres becomes harder as the aspect ratio increases. Shotcrete steel fibres are available in different lengths, ranging from 20 mm to 40 mm. Among them, all 30 mm and 35 mm fibres have proven to be the most effective.

The relevance of aspect ratio steel fibre is as follows:
(1) an increase in steel fibre dosage and aspect ratio negatively impacted workability, owing to the interlocking between fibre
(2) compressive strength was positively influenced by the steel fibre dosage and aspect ratio
(3) a faster loading rate significantly improved the mechanical properties. There were also some shortcomings in the measurement method for setting time.

The ultimate tensile strength (UTS) is a material's maximum resistance to fracture. In a uniaxial stress-strain test, the ultimate tensile strength (UTS) refers to the highest engineering stress that a material can withstand when exposed to simple tension. This is measured as the maximum load that can be supported by one square inch of cross-sectional area.
