Concrete (or mortar) special BR-PVA fiber is an environmentally friendly cementitious enhancement material successfully developed by our company. Due to its unique molecular structure, it has excellent dispersibility and alkali resistance in concrete (or mortar). In concrete (or mortar), BR-PVA fiber can significantly reduce plastic shrinkage cracking and prevent temperature and shrinkage cracks, and also suppress crack development and improve the strength, toughness, and durability of the material. It is suitable for various industrial and civil building applications such as roofs, ground, basements, bridges, pavements, and precast concrete components.Compared with steel fiber, glass fiber, polypropylene fiber, and asbestos commonly used in cementitious composite materials, BR-PVA fiber has better dispersibility. In concrete, the construction and application fields have broad development prospects.

It is suitable for various industrial and civil building applications such as roofs, ground, basements, bridges, pavements, and precast concrete components.
Compared with steel fiber, glass fiber, polypropylene fiber, and asbestos commonly used in cementitious composite materials, BR-PVA fiber has better dispersibility. In concrete, the construction and application fields have broad development prospects.
Crack resistance, anti-seepage
Cast-in-place reinforced concrete structures, such as high-rise building transfer beams, columns, and floor slabs.
Industrial and civil prefabricated concrete products, such as underground engineering, water-resistant panels, and pavement slabs.
High-performance self-compacting concrete.
High-strength and crack-resistant mortar, chemical-resistant mortar.
For sand-mixing process, mix the fiber with sand first, then add cement and mix evenly. Alternatively, the fiber can be added directly to the mixer, and mixed with water (pre-wetting the fiber in water can also improve mixing uniformity).
For batch mixing, add the fiber to the aggregate as per the required amount. For pre-mixed fiber, it can be directly used in the concrete if no prolongation of mixing time is necessary, with a mixing time of 30-60 seconds.
The typical dosage range is {{0}}.6-1.9kg/m³, with the common dosage being 0.9kg/m³.
The product is non-toxic and non-flammable. Store in a dry place at room temperature to ensure safety.
Common packaging includes 20kg/bag, and two-layer packaging using polypropylene woven bags lined with polyethylene film. Customized packaging is available upon request.
Non-toxic, non-flammable; safe and environmentally friendly.
Simple to construct, cost-effective.
