Glass fiber chopped strand using water dispersible infiltration agent, stirring dispersion directly into single fiber in the water, can also be used directly in the cement concrete, mortar, such as direct mixing, with rapid dispersion, named with tiny fiber can achieve enhanced effect.But also enhance the mortar concrete anti-seepage crack excellent inorganic fiber, and replace the polyester, lignin fibers used for mortar concrete such as competitive products, also can improve the high-temperature stability of asphalt concrete, the low temperature crack resistance and fatigue resistance and prolong the service life of road surface.
