twisted fiber Description:
Polypropylene Twist Macro Fiber is developed for replacement of steel fiber, with polypropylene as its raw material;it is produced by special drawing twisting and surface treatment. Compared with steel fiber, it has advantages of acid, alkali resistant, excellent tensile, easy dispersing, convenience for construction and no damage to the mixing equipment.

twisted fiber Applying Instruction:
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 5.5kg, Compared with adding 47kg
of steel fibre, 5.4kg polymer fibre has the same volume ratio to the concrete.
50mm or 54mm for common crack-resistant requirement.
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 per sqm
of 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.
Improve the crack-resistence in large scale of cement concrete for industrial workshop, warehouse, parking lot, airport, underground engineering, Hydraulic work ect.
