What are AR Glass Fibers?
AR Glass Fiber (Alkali-Resistant Glass Fiber) is produced from glass with high alumina and silica content, which gives it excellent resistance to alkaline media and makes it ideal for use in cementitious materials.
Fiberglass AR has established itself as an essential material in engineering and construction, thanks to its alkaline resistance, high mechanical strength and durability. With the advance of technology and the optimization of production processes, its application will continue to expand in multiple sectors, improving the quality and sustainability of modern infrastructures.
AR Glass Fiber (Alkali-Resistant Glass Fiber) is a state-of-the-art material designed to reinforce and improve the mechanical properties of concrete and mortar, providing an effective solution to prevent cracks, increase structural strength and extend the useful life of constructions. Thanks to its high resistance to alkalinity, this fiber is ideal for integration into cementitious mixtures, avoiding degradation caused by the aggressive cement environment and offering superior performance in structures subjected to dynamic loads, temperature changes and exposure to chemical agents.
From road infrastructures to industrial and residential buildings, AR Fiberglass has become an innovative alternative to traditional reinforcements, ensuring better stress distribution in the material and improving the ability of concrete to resist extreme mechanical stresses. Its compatibility with a wide range of applications makes it indispensable in modern, sustainable and high-performance construction.
The incorporation of AR Fiberglass in cementitious mixtures generates a series of structural and functional improvements that optimize the quality of construction materials. Its main benefits include:
- Reduction of fissures and cracks: Reduces the formation of micro-cracks caused by plastic shrinkage, reducing the possibility of structural fractures.
- Increased mechanical strength: Increases the concrete’s capacity to withstand tensile, bending and impact loads, improving its behavior in the face of external forces.
- High resistance to alkalinity: Its special formulation prevents degradation in high pH environments, ensuring greater durability.
- Improves impermeability: Minimizes water absorption and penetration of corrosive agents, reducing moisture and internal corrosion problems.
- Lightness and ease of application: It does not alter the workability of the concrete and is homogeneously dispersed in the mixture without generating accumulations.
- Increased resistance to extreme conditions: Increases the tolerance of concrete to high temperatures, freeze-thaw cycles and exposure to aggressive chemicals.
- Cost optimization: Reduces the need for maintenance and extends the useful life of structures, reducing long-term costs.
🏗 Road Infrastructure and Bridges: Increases strength in roads, highways and urban pavements, minimizing cracks and deformations.
🏢 Commercial and Industrial Buildings: Application in walls, slabs and concrete panels to improve stability and avoid cracks.
🌊 Hydraulic Works and Marine Structures: Use in dams, canals and hydraulic tunnels for greater impermeability and erosion resistance.
🚇 Tunnels and Mining: Improves the stability of galleries and tunnels exposed to extreme conditions and high impact loads.
🏠 Residential and Prefabricated Construction: Facade reinforcement, modular structures and prefabricated panels for greater safety and durability.
🏭 Industrial Floors: Increases resistance in floors subjected to heavy traffic and dynamic loads in warehouses and factories.
To ensure correct application and maximum performance, it is recommended to follow these guidelines:
Recommended Dosage
- Standard mortar: 0.9 – 1.2 kg/m³
- Structural concrete: 0.6 – 2.7 kg/m³
- Thermal insulating mortar: 1 – 3 kg/tonne
Presentation and Packaging
- 1 kg per individual package
- 25 kg per bag
- Customized packaging according to customer requirements
1️⃣ Measure the exact amount of fiber according to the mixture to be used.
2️⃣ Add the fiber to the dry aggregates in a forced mixer blender, ensuring even distribution before adding the water.
3️⃣ Dry mix for 30 seconds, then add water and continue mixing for another 30 seconds to ensure a homogeneous dispersion.
4️⃣ Check the dispersion of the fiber in the mixture. If there are accumulations, prolong mixing for an additional 20-30 seconds.
5️⃣ Pour and cure following the standard process for conventional concrete.
