Polypropylene fiber used in concrete percolating-proof synthetic fiber |
Product introduction |
Polypropylene fiber with 100% PP YuanJiao as raw materials, in the special design of special fiber production line with short fibers made of engineering, the product can significantly improve concrete brittleness, strengthen the continuity of concrete material medium and uniformity, and effectively reduce concrete plasticity cracking of concrete, and can be widely applied percolating-proof engineering. | |

Technical features |
■S good dispersion |
|
Polypropylene fiber via special surface treatment technology to ensure the fiber in concrete has the extremely dispersion and cement matrix grip wrapped force. |
■S superfine fibber |
|
Minimum of polypropylene fiber diameter is 18 muon m, compared with similar products superfine fibers.。Usable smaller admixture provide more number of reinforced concrete, for providing better protection. |
■S excellent crack effect |
|
Polypropylene fiber already through many authoritative organizations of testing, the results show that the polypropylene fiber has remarkable anti-cracking ability, the crack resistance level to level (optimal). | |
applications |
|
■S rc rigid from waterproof structure basement slabs, side wall, roof and roof floor, and pools ■S cement mortar, dry mortar insulation mortar, anti-crack mortar,内(外)墙抹灰砂浆Inside the wall plastering mortar (outside) ■S anti-crack, impact resistance, abrasion resistance, high seismic requirements for the occasion ■S bridge, the pier and ports, water conservancy project, super-length structure ■S anti-explosion, refractory occasions: defent engineering;耐火材料refractory ■S shotcrete: tunnel lining, thin-walled structure, slope reinforcement |
Product packaging |
■S standard packet containing o. is 6 kg or 0.9 kg two kinds, packaging materials have plastic bags and pulp | |
Product packaging |
paper bag two kinds. the standard big packing for plastic woven bag packing. can be based on user needs to provide special small package. |
instructions |
■structure design |
|
Polypropylene fiber on concrete enhancement is a physical function, in principle concrete proportioning design does not change. |
■ |
Proportioning design |
|
The admixture scope: 0.6-180 kg/m3, concrete percolating-proof usually admixture for o. 9kg/m3, if need to achieve high technical requirements, can use high dosage. |
■length selection |
|
Mortar mainly choose 6mm or 12mm, concrete chooses in 19mm 12mm or. |
■construction instructions |
|
For mixing equipment and construction techniques of no special requirements.When construction, can according to mix directly will fiber input blender, as long as appropriate extension whisking time, make the fiber in concrete evenly spread among can. |
■attention |
|
Irreplaceable structural strengthening material, also not to reduce the main structure size.Could not be used for solving settlement, mass concrete hydration heat and powerful external shocks occasion.Cannot because fiber used and reduce construction quality requirements, still should press national technical regulations, carry out construction and maintenance. | | |
