PVA fiber: a new favorite in the field of concrete and a new choice for improving engineering quality
PVA fiber is a widely used reinforcing material in concrete engineering. Its characteristics lie in its alkali resistance, high strength, and good crack resistance, which can significantly improve the crack resistance, toughness, and durability of concrete. It is mainly used for crack prevention engineering of concrete structures such as wind power foundation bases, docks, hydropower stations, tunnels, bridge pavements, etc. Suppressing plastic shrinkage cracks in cement mortar and concrete before solidification increases the toughness of concrete.
