Product Description
Polypropylene Fibre
(PP fiber) -- Twist / Bunchy form
Description:
This fibre is used to instead of steel fibre for reinforcement to cement concrete. Compared with steel fibre, it has the advantage of easy dispersing and blending, no damage to the mixing equipments, etc.
The rigid polymer fibre is used polypropylene as its raw material, produced the rough surface treatment by special parallel thread extruding & twisting process. It has high break strength, better dispersion and strong combining ability, will be widely used to instead of steel fibre to reinforce the cement concrete and crack resistant.
Main Technical Specification:
Density (g/cm3) 0.91 +/- 0.01
Elastic Modulus (MPa) >3500
Length (mm) 20, 30, 50, 54mm
Equivalent Dia (mm) 0.3+/-0.05
Shape bundle-like and twisted
Break tensile Ratio (%) 8-15
Crack Ratio 20+/-5 %
Melting point (C. Deg) 160-170
Tensile Strength >450 mpa
Water absorbency NO
Break Strength(MPa) >350
Resistance to acid, alkali strong
Application:
1, Ration design of the fibre concrete:
Generally the recommended amount to add to the concrete is more than 2.7kg per sqm (volume ratio is 0.3%), reinforcement adding amount is 5.4kg. Compared with adding 47kg of steel fibre, 5.4kg polymer fibre has the same volume ratio to the concrete.
2, length: 50mm for common crack-resistant requirement, for spray concrete, length not more than 30mm.
3, Matching Ratio:
Usually, it is no need to Change the matching ratio of the concrete.
Considering the requirement of fissure-resistant, the polymer fiber is recommend to combine with the polypropylene fiber mesh with the volume ratio of 1: 1 (0.9kg fiber-mesh to per sqm cement concrete).
4, Mixer Adoption: Double-axle horizontal compelling mixer is priority.
5, Mixing process: Crushed stones, fibers and sands are put into the mixer in succession. After stirring for two minutes, fiber will fully spread and then add cement and water and stir normally. The addition of materials also
Can be put into as common concrete, but the stirring time should be properly prolonged to make fiber completely Mixed.
6, Shaping & Maintenance
There is no special requirement, may along the vibrating time for 30s, The maintenance of the fibre concrete should be done same as the normal concrete.
7, Package: 1kg or 0.9kg per bag in common, 10kgs per carton.
May packed as customers' requirement, Water soluble bag is available also.
Economy
Compared with steel fiber, Polymer fibre has the advantages of corrosion and wear-resistant reducing 50% cost with same volume to steel fibre.
