Product Description

Fibres

Cracks play an important role as they change concrete structures into permeable elements and consequently with a high risk of corrosion. Cracks not only reduce the quality of concrete and make it aesthetically unacceptable but also make structures out of service. If these cracks do not exceed a certain width, they are neither harmful to a structure nor to its serviceability. Therefore, it is important to reduce the crack width and this can be achieved by adding polypropylene fibres to concrete.

Thus addition of fibres in cement concrete matrix bridges these cracks and restrains them from further opening. In order to achieve more deflection in the beam, additional forces and energies are required to pull out or fracture the fibres. This process, apart from preserving the integrity of concrete, improves the load-carrying capacity of structural member beyond cracking. Reinforcing steel bars in concrete have the same beneficial effect because they act as long continuous fibres. Short discontinuous fibres have the advantage, however, of being uniformly mixed and dispersed throughout the concrete.

The major reasons for crack formation are Plastic shrinkage, Plastic settlement, Freeze thaw damage, Fire damage etc.

Types of PP Fibres Supplied by us:
1. Macrosynthetic Polypropylene Fibres (Structural Fibre): This kind of fiber is superior to conventional reinforcement in shotcrete that can outperform, assure cost saving, and is easy to use.

2. Fibrillated Polypropylene Fibres (Non Structural Fibre) or Micro PP Fibre: The products appear net-like structure with many fiber monofilaments connected. When the fiber is put into the concrete, the horizontal structure in fiber monofilament can be destroyed in the course of stirring owing to friction and rubbing, and the fiber monofilament or net-like structure will fully stretch, thus the concrete is reinforced by a great number of polypropylene fibers.

3. Monofilament Polypropylene Fibres (Non Structural Fibres): It is used to inhibit the formation of small cracks which can occur through plastic shrinkage, premature drying and early thermal changes in order to provide utilizations of the intrinsic properties of hardened cementitious materials. Monofilament fibers do not affect the chemical hydration of the cement and are compatible with all concrete mixes and admixtures. It creates an internal support system which results in more uniform bleeding thereby discouraging segregation and settlement of the concrete ingredients.

b. Cellulose Fibres:

(Hercules Fibres)

These are manufactured in USA by HERCULES GROUP SA, and Karanwal Infratech Materials Pvt. Ltd. is sole distributor / supplier in INDIA.

Cellulose fibers (Hercules FibersĀ® D5) provide an excellent preventive solution to plastic shrinkage cracking in concrete. Our alkali resistant fibers are invisible in concrete, and have been shown to enhance concrete hydration, resulting in higher compressive strength and better freeze/thaw durability of concrete. They improve finish ability, enabling you to achieve aesthetically excellent surface of your concrete. From fresh concrete to concrete repair, from poured concrete to shotcrete, from on-site concrete placement to precast concrete applications, These Fibers have shown excellent results in controlling cracks, which are a first step in the degradation of concrete. We committed to bringing this excellent USA made product to your market. Please contact us for further information.
Hercules FibersĀ® D5 is the next generation of reinforcing fiber for concrete because it is:

  • Capable of achieving excellent results
  • Champion in its class
  • Convenient to use
  • Certified and confirmed by lab tests
  • Cost-effective to save you money

c. Glass Fibre:
Glass Fibre is a fibre reinforced polymer made of a plastic matrix reinforced by fine fibre of glass. It has many applications in various fields of engineering & industrial. Most common use of glass fibre is in the manufacturing of Glass Fibre Reinforced Concrete.

Glass fibre Reinforced Concrete (GRC) is one of the most versatile building materials available to architects and engineers having only 20% of the weight of pre-cast concrete, making it easier to handle on site and reducing loads on structures when in use. GRC is also strong with a higher tensile strength than precast concrete allowing thinner wall sections to be produced.

Glass fibre Reinforced Concrete (GRC) applications including:

  • Architectural cladding
  • Moulding and landscaping
  • Roofing, walls and windows
  • Building renovation
  • Foundations and flooring
  • Modular building
  • Permanent formwork
  • Rail cable channelling
  • Acoustic barriers and screens
  • Bridge and tunnel lining panels
  • Water and drainage

d. Polyester Fibres:
We are in league with the prominent supplier and exporters of Polyester Staple Fibre. Our product range includes Polyester Staple Fibre, Polyester Staple Fibre (virgin) and Polyester Fibre. These fibres are fabricated in adherence with international norms and standards and are highly efficient in performances. We stringently test all these fibres for quality at our technologically advanced laboratory for quality checking. Offered fibres are highly reliable and are appreciated for their accurate composition. Patrons can avail these fibres from us in different capacities.

e. Basalt Fibre:
Basalt fibre is a material made from extremely fine fibres of basalt, which is composed of the minerals plagioclase, pyroxene, and olivine. It is similar to carbon fibre and fiberglass, having better physic-mechanical properties than fiberglass, but being significantly cheaper than carbon fibre. It is used as a fireproof textile in the aerospace and automotive industries and can also be used as a composite to produce products such as camera tripods.

The first attempts to produce basalt fibre were made in the United States in 1923. These were further developed after World War II by researchers in the USA, Europe and the Union especially for military and aerospace applications. Since declassification in 1995 basalt fibres have been used in a wider range of civilian applications.

Uses:

  • Heat protection
  • Friction materials
  • High pressure vessels (e.g. tanks and gas cylinders)
  • Load bearing profiles
  • Windmill blades
  • Lamp posts
  • Ship hulls
  • Car bodies
  • Sports equipment
  • Concrete reinforcement (e.g. for bridges and buildings)
  • Speaker cones
