 Macro polypropylene fiber for shotcrete synthetic concrete fiber for construction monofilament fiber

Sprayed fiber concrete has been widely used in permanent support of underground projects at home and abroad. Steel fiber is mainly used. Steel fiber has large weight and high cost, especially its poor corrosion resistance under corrosive environmental conditions, which directly affects the durability of concrete. Polypropylene coarse fiber has good dispersion and adhesion with cement matrix, which has the function of steel fiber, It also has the advantages of synthetic fiber, good chemical stability, light weight and relatively low cost. In recent years, domestic polypropylene crude fiber has gradually begun to be used.
