Concrete Fiber, Polypropylene Monofilament Type

Polypropylene monofilament type concrete fiber, also named polypropylene micro fiber, is a high-strength bunchy monofilament fiber. It is produced by a functional master batch modified with special surface treatment, which is a foreign advanced technology introduced by our company.

Concrete fiber features good dispersion, strong hydrophilic, strong bond with cement, etc. Due to its tridimensional network structure, polypropylene monofilament fiber mixed with concrete or mortar can efficiently control micro cracks of concrete or mortar resulted from such factors as plastic shrinkage, drying shrinkage, temperature changing and so on. Then, it can prevent and inhibit the formation and further development of cracks especially in fire environment and it can also significantly improve concrete crack resistance, impermeability, freeze-thaw resistance, shock resistance and earthquake resistance.

Concrete fiber can be widely used for waterproofing of underground works, industrial and civil engineering such as roof, wall, floor, pool and basement, municipal engineering such as airport, wharf, subway, sleeper, warehouse, highway, precast parts and sprayed concrete, as well as road and bridge engineering, etc.

  • PCL Polycarboxylate Superplasticizer Concrete AdmixturePCL polycarboxylate superplasticizer concrete admixture features good stability especially at low temperature. Besides, the liquid concentration of our product can be diluted from 50% to 10% and then you can directly use the diluted product as pumping admixture of mixing plant.
  • FDN Naphthalene Sulfonate Formaldehyde Condensate Concrete AdmixtureCompared with UNF-5 type, FDN naphthalene sulfonate formaldehyde condensate concrete admixture has higher water reducing rate and fewer concrete slump loss, which can efficiently increase the concrete fluidity, reduce bleeding and segregation and then improve the workability of concrete.
