Alkali Resistant Glass Fibres – 6mm HD
6mm HD fibre is an alkali-resistant glass chopped strand fibre specifically engineered for use in concrete and sand/cement screeds.
Adding to the screed mix will reduce plastic shrinkage cracking and increase impact & abrasion resistance.

Application
6mm HD fibre is typically used at low addition levels to prevent cracking and improve the performance of concrete, flooring, renders and screed 6mm HD fibres will incorporate easily into mixes creating a tri-dimensional homogeneous network of reinforcement throughout the cement matrix.
6mm HD fibre will not protrude through the concrete surface and requires no additional finishing procedure.
The HD fibre reinforcement is incorporated in the concrete mass and is invisible on the finished surface. 6mm HD fibre will provide secondary reinforcement in all concrete applications.
Recommended dosing: Dosage rates will be dependent on mix design, process, types of aggregates and the desired effect, but typically: 1 x 450g bag per cubic metre To meet freeze-thaw requirements: 1 x 450g bag per tonne or 2 x 450g bags per cubic metre
STANDARDS
6mm HD fibre complies with ASTM C1116/C, 1666/M-07 and EN 15422 requirements.
SUMMARY OF BENEFITS (vs. concrete containing no fibre)
• Compressive Strength +13%
• Flexural strength +15%
• Bleeding -25%
• Plastic Shrinkage Cracking -86%
• Permeability -50%
• Freeze / Thaw Expansion -66%
Compatibility: 6mm HD fibre is compatible with all types of EN 197 cement systems and offers a wide range of benefits, particularly in the production of sand/cement screed.
Storage: Store the product in a dry environment, moisture ingress will cause the water-soluble bags to degrade.
Handling: Please refer to the 6mm HD fibre Material Safety Data Sheet but in line with normal handling procedures, personal protective equipment should be worn.
Packaging: 6mm HD fibre is supplied in 450-gram water soluble bags, 30 bags per box.
