Spiral PVA fiber designed for wind power foundation concrete, providing effective crack control and long-term durability.
Summary Benefits at a Glance
Spiral shape improves bonding and uniform dispersion
Crack and shrinkage control, enhancing toughness and impact resistance
Resistant to alkali, chemicals and UV, safe and non-toxic
Suitable for precast, pumped and shotcrete applications
Product Introduction
Spiral Polyvinyl Alcohol (PVA) Fiber is developed for wind power foundation concrete and other large-scale civil works. Its spiral geometry enhances bonding with cement matrix and dispersion in fresh mixes. The fiber delivers excellent crack resistance, toughness, permeability reduction and freeze–thaw resistance. It is non-toxic, alkali-resistant, UV-resistant and stable in cementitious environments. Widely used in wind power foundations, bridges, tunnels, industrial flooring, precast elements and shotcrete.
