Since the mid-1980s, high-strength polypropylene filament concrete in our civil engineering and transportation industry gradually applied, such as the basement of high-rise buildings, sewage treatment plant effluent pond, swimming pool and other projects.

Since a large number of high-strength polypropylene fiber filament random distribution in concrete, so that deformation of the concrete structure after the initial cracking residual strength and toughness have some increase. Further high-strength polypropylene filament concrete with high viscous, improve performance and reduce shotcrete rebound. All these features make the high-strength polypropylene yarn become an important measure for more than 20 years abroad to improve the performance of concrete.

Laboratory tests and engineering practice proved that adding a low dosage levels in concrete high-strength fiber wire, can reduce or prevent the hardening of the concrete after pouring the early stages, due to bleeding and water loss caused by plastic shrinkage and microcracks to be reduce and prevent the hardening of concrete post-generating micro-cracks and shrinkage cracks caused by temperature changes, thereby improving the performance of concrete seepage, frost, abrasion resistant and so on.

Chi Chun Textile Co., Ltd. has been working with the manufacturers to focus high-strength fiber wire, our products are excellent, very welcome. Need please contact with us if you have.
