Basalt fiber chopped strands are made by chopped continuous basalt fiber roving,which is coated with silane sizing outside. It is the most preferable material for reinforced thermoplastic resin, and the best choice for glassfiber reinforced concrete(ie.GRC material). Basalt is a kind of high performance volcanite component,this special silicate makes basalt fiber with good chemical resistance and alkali resistance. Basalt fiber is more often used in the glassfiber reinforced cement instead of polypropylene (PP) and polyacrylonitrile (PAN). And it is a competitive replacement for polyester fiber and lignin fiber in asphalt concrete.It can fully improve concrete stability at high-temperature, crack resistance at low temperature and fatigue resistance and so on.
