          RQS ? -Ⅵ is comprised of short, thin fibers, predominantly comprised of Polyacrylonitrile (PAN), with a non-circular section shape made by wet spinning for fiber-reinforced high-performance concrete and mortar. The fiber possesses excellent dispersion in cement-based materials with an effective bonding property between fiber and the matrix due to the surface treatment of hydrophilic modification. RQS ? -Ⅵ can decrease and impede the plastic and drying shrinkage of cement-based materials. It can also significantly improve the crack-resistance, impermeability, impact and fire resistance of cement-based materials.
