Macro Synthetic PP fibres (PP macro fibres)is made of polypropylene as raw material by special technology. Its special shape greatly improves the bonding force in concrete, and at the same time it has the characteristics of high fracture strength and easy dispersion, which greatly improves the crack resistance of concrete, improves the characteristics of low tensile strength, low ultimate elongation and brittleness of concrete, and prolongs the service life of concrete. Compared with steel fibers, steel fibers have the characteristics of corrosion resistance, dispersion resistance, non-destructive construction and mixing equipment, so they can be used in cement concrete instead of steel fibers.
