Basalt Fiber Concrete

Reinforcement Directly Inside the Mix

Short basalt fibres are used as a reinforcing addition in concrete and cement-based mixtures to create basalt fibre reinforced concrete. Chopped basalt fibres and microfibres are described as reinforcing agents in gypsum, cement paste, tile adhesives, mortar layers, and base coatings, as well as additives in concrete, asphalt, cement, and gypsum-based combinations.

Its main goal is to enhance the final material's performance rather than to replace concrete. According to the research presented, basalt fibres can improve flexural, axial tensile, compressive, impact, and splitting strength while also minimising splintering and cracking. Additionally, it can lessen fire-induced explosive spalling. Because basalt doesn't absorb liquids, the concrete's integrity is preserved.

A Practical Alternative to Metal Reinforcement

One benefit of basalt fibre reinforced concrete is that it may be included into current concrete mixing operations without necessitating process modifications. In comparison to traditional reinforcement techniques and metal mesh, the data also shows reduced labour intensity and material costs. Its lesser weight makes handling and shipment on building sites easier than with steel reinforcement.

Foundations and footings, precast slabs, drainage structures, curbs, benches, planters, floor mortar layers, and commercial or industrial flooring are some examples of applications. The article also lists applications in chemical plants, wastewater treatment facilities, and marine areas where corrosion resistance is crucial.

For this reason, basalt fibre reinforced concrete serves mainly as a reinforcement option for concrete producers. Instead of using basalt fibre as a one-size-fits-all additive, the fibre length, diameter, size, and dosage should be chosen based on the concrete formulation and desired performance.
