 Polypropylene staple fiber content is 0.6-1.8 kg / cubic meters of mortar or concrete, is generally 0.9 kg / cubic meter of mortar or concrete. According to the project site and regional fiber content should be different content for the site of freezing and thawing relatively calendar harm geographical and abrasion calendar harm should be higher. 







 Polypropylene staple fiber mortar / concrete cracking, impermeability, abrasion resistant, frost ability, antiknock ability and improve concrete workability. Tens of millions of fibers evenly distributed in the mortar / concrete, played the role of the good micro-reinforcement, so good to maintain the structural integrity, to avoid the structure subjected to impact damage, dispersed into many fragments, to prevent the structure corrosion of the reinforcement, can greatly extend the life of the project, reduce the maintenance costs of the project.
