Alkali Resistant Glass fibres add strength and flexibility to the concrete resulting in a strong yet light-weight end product. The alkali resistance of Glassfibre depends principally on the content of Zirconia (ZrO2) in the glass.

Benefits:

• The AR glass is itself alkali resistant, It does not depend on any coating
• Fine individual filaments: a very large number of fibers are released when mixed in the concrete and the filament does not protrude from the surface and be invisible when the concrete surface weathers.
• Have a high tensile strength to withstand stresses during shrinkage.
• Have a high modulus of elasticity to absorb shrinkage stresses before the concrete cracks.
• Have a superior bond(mineral/mineral interface) with the concrete.
• Present no health hazards.
• AR glass fibers reinforce both plastic and hardened concrete

Anti-Crack glass Fiber solution for every type of cracking. From the micro to the macrofiber range,Anti-CRAK® fibers control cracking processes that can take place during the entire life-span of concrete. it provides a higher peak strength than plain concrete, due to the total bond between fiber and matrix, which allows the contribution of the fiber action even before the peak load, at the very beginning of the microcracking process. 

Why glass fiber?

With its total affinity to cementitious composites, high tensile strength and modulus of elasticity, glass fibers are an ideal reinforcement for concrete, already efficient at very early stages of the cracking process. Moreover, glass fiber density is similar to concrete, which allows a quick dispersion for very short mixing times, with minimum clumping risk and exceptionally low influence on workability.

Anti-CRAK fibers as concrete reinforcement

There is an Anti-CRAK® solution for every type of cracking. From the micro to the macrofiber range,Anti-CRAK® fibers control cracking processes that can take place during the entire life-span of concrete. From cracks due to volume changes in fresh (settlement and plastic shrinkage) and hardened states (thermal and drying shrinkage), to post-crack load-bearing capacity contribution.

Technical performance of Anti-CRAK fibers

PLASTIC SHRINKAGE CRACKING Product:
Anti-CRAK® HD I 2mm @ 0.6kg/m3

Solution to control plastic shrinkage cracking in combination with standard curing practices, in flooring applications under severe environmental conditions.SECONDARY REINFORCEMENT:

Thermal and shrinkage cracking prevention Product:
Anti-CRAK® HP 67/36 @ 5kg/m3.

Alternative solution to anti-cracking mesh in order to control thermal and drying shrinkage cracking in residential and light commercial floors.

PRIMARY REINFORCEMENT:

Steel mesh and rebar replacement Product:Anti-CRAK® HP 67/36 @ 5-I5kg/m3

At different levels of fiber addition Anti-CRAK® HP 67/36 provides a higher peak strength than plain concrete, due to the total bond between fiber and matrix, which allows the contribution of the fiber action even before the peak load, at the very beginning of the microcracking process. Subsequently,Anti-CRAK® HP 67/36 provides residual strength over a large range of crack openings.

Application Range

The high flexural performance of Anti-CRAK® HP 67/36 makes this fiber an ideal solution to replace conventional steel reinforcement in a wide range of applications.
