Glass Fibre Reinforced Concrete

Glass fibre reinforced concrete offers a range of advantages over traditional concrete, making it particularly attractive for specific construction applications and architectural designs:

• Tensile and bending strength: The spraying process cuts the glass fibre strand into short fibres, which are evenly integrated into the fine concrete matrix with a random orientation. Unlike placing reinforcement in mat form, this method does not require minimum coverage, and the reinforcement is distributed not only in a single plane of the glass fibre reinforced concrete element but throughout all load-bearing layers, except for the surface layer. This allows the excellent material properties of sprayed glass fibre reinforced concrete to be achieved.
• Corrosion resistance: Improved stress absorption minimises crack formation, giving the material its high ductility. Carbonisation and possible degradation of the concrete are effectively prevented due to the alkali-resistant glass fibres, with positive effects on the lifespan of the concrete surfaces. The corrosion resistance of the glass fibres eliminates additional problems like rust in the reinforcement and the associated repair costs.
• Thinner components: The reduced concrete cover allows for more delicate and lighter elements, which has a positive impact on both design and cost.
• High adaptability: Glass fibre reinforced concrete can be moulded into a variety of shapes and textures, enabling creative architectural solutions.
• Lightweight: The lower weight of glass fibre reinforced concrete reduces the load on the supporting structure, leading to cost savings in the foundation and structural support of the building. Additionally, there are benefits throughout the entire logistics chain: a lower weight results in better transport conditions and easier, quicker assembly with lighter lifting equipment.
• Sustainability: Reduced material consumption and a long lifespan contribute to the sustainability of construction projects. Moreover, the lower weight and faster assembly also result in CO2 savings.
• Weather resistance: Glass fibre reinforced concrete is generally resistant to environmental influences such as freeze-thaw cycles, wet-dry, or heat-rain changes.
