Glassman® MICRO FIBRES
Advanced AR Glass Fiber Reinforcement for Concrete and Cement-Based Materials. Glassman Micro Fibres are alkali-resistant (AR) glass fibres engineered for reinforcement of concrete and cement-based materials. These micro fibres help control micro-cracking that naturally occurs in fresh concrete and improve the durability and performance of glass fiber reinforced concrete (GFRC) and other cementitious systems throughout their service life.
When incorporated into concrete or plaster mixes, Glassman® Micro Fibres reduce cracking caused by plastic shrinkage, thermal movement, drying shrinkage, and settlement. The fibres provide distributed micro-reinforcement within the concrete matrix, improving crack resistance and enhancing overall structural performance.
Glassman Micro Fibres are widely used in industrial flooring, plaster reinforcement, precast concrete products, roads, pavements, and infrastructure applications where improved crack control and durability are required.

Glassman® MICRO FIBRES?
Glassman® Micro Fibres provide uniform micro-reinforcement for concrete and cementitious materials, helping improve the performance of concrete structures during early curing and throughout their service life.
The alkali-resistant (AR) glass fibres disperse evenly within the mix and act as crack-bridging reinforcement, helping limit crack propagation and improve durability. With a density of approximately 2.68 g/cm³, similar to concrete, the fibres integrate effectively within the concrete matrix and distribute reinforcement consistently.
This improves crack control, durability, and long-term structural stability in concrete, GFRC systems, and cement-based construction applications.

FAQ
GFRC (Glass Fibres Reinforced Concrete) is a composite material where alkali-resistant glass fibres are uniformly dispersed within a cementitious matrix to improve tensile strength and control cracking. GFRC are commonly used in construction applications requiring durability and crack control, including industrial flooring, precast elements, pavements, plaster reinforcement, and thin panels.
Glassman® MICRO FIBRES improve concrete by acting as micro-reinforcement within the concrete matrix.
The fibres bridge microcracks and distribute stress throughout the material, helping reduce shrinkage cracking, improve abrasion resistance, and enhance the long-term durability of concrete structures.
Glass Fibre Reinforced Concrete improves durability, reduces shrinkage cracking, and enhances abrasion resistance compared to conventional concrete. It aids in reducing water permeability and provides uniform reinforcement throughout the concrete matrix, improving the overall service life of structures. They are also resistant to rust and fre.
Glass fibre dosage in concrete depends on the application, mix design, and crack-control requirements.
Typical dosage ranges from 0.9 kg per bag of cement to 1 kg per cubic meter of concrete, although final
dosage should be confirmed through mix design testing and engineering recommendations.
