Product Specification

We offer our clients with concrete fibers like Anti Crak TM HD glass fibers which are widely appreciated for their high quality. These concrete fibers reduce plastic shrinkage cracking, up to 86.3 %( Kraai Test) and increase compressive strength by 13%. Our concrete fibers find their application in Floor screeds, Ready mix concretes, RCC, Dry mix renders and Mortars.

Concrete Reinforcement Fibers
WHY FIBERS IN CONCRETE?
It is widely accepted within the concrete industry that traditional concrete mixes are prone to plastic shrinkage during the setting phase and this can often lead to cracking.

The addition of relatively small amounts of concrete reinforcement fibers can effectively reduce this problem by controlling this early-age plastic shrinkage cracking. Concrete reinforcement fiber also avoids the need for using light steel mesh for crack control with its attendant disadvantages of handling and positioning.

Fiber reinforced concrete is easy and cost effective and and it also enables you to produce a hardened concrete which has :

- Improved surface quality
- Greater impact resistance
- Increased durability

WHY ANTI-CRAK?
Anti-Crak Concrete Reinforcement Fibers are alkali resistant glass fibres, especially developed for the reinforcement of cementitious mortars and concrete mixes. They can be easily introduced into a conventional concrete mix giving millions of dispersed fibers per cubic meter of concrete, providing a highly uniform and effective concrete fiber reinforcement.

Anti-Crak fibers give you :

High modulus of elasticity for effective long-term reinforcement, even in the hardened concrete.
A reinforcing material which does not rust nor corrode and requires no minimum cover.
Ideal aspect ratio (i.e. relationship between fibre diameter and length) which makes them excellent for early-age performance.
A fibre which is safe and easy to handle and does not protrude through the finished surface nor sink.

Properties :

ANTI-CRAK HD (High Dispersion)

These concrete reinforcement fibers are designed to be used with normal concrete mixes at very low addition levels - typically 0.6kg/m3 (Mb/yd3) of concrete. Added directly to the mixer or ready mix truck they disperse instantly within the concrete. This complete uniform dispersion ensures a three dimensional reinforcement throughout the matrix and thus an effective suppression of cracking during the plastic shrinkage period. The large number of filaments gives a very small distance between fibers whilst the high aspect ratio gives maximum effect in the setting period. Anti-Crak High Dispersion fibers can be simply added to the mix either on site or at the mixing plan: without the need of a special equipment Standard concrete mix designs are used. Extended mixing times are not necessary.

ANTI-CRAK HP (High Performance)
These fibers are normally used at higher addition levels - usually from 3-IOkg/m3 (5-l7lb/yd3) of concrete. Anti-Crak High Performance fiber is a highly integral product which is resistant to fiber bundle breakdown in concrete mixing - useful when mixing time and conditions are variable. This physical form enables a higher rate of addition to be achieved without adversely affecting workability although conventional superplasticisers may be used to improve workability. Ideal for improving performance of both in situ and precast concrete as well as renders Anti-Oak.

High Performance fiber give :

Greater retained toughness in conventional concrete mixes
Increased impact strength and abrasion resistance
Higher flexural strength, depending on addition rate
