Biture Grey PP Fiber Twisted Bunchy Form For Reinforcement To Crack Resist And Concrete
PP Fiber Twisted Bunchy Product Description
1. This fibre is used to instead of steel fiber for reinforcement to cement concrete. Compared with steel fiber, it has the advantage of easy dispersing and blending, no damage to the mixing equipments, etc
2. 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.
PP Fiber Twisted Bunchy Application
1. PP fiber twisted bunchy can be used for the surface of road, bridge, runway and floor of the factory.
2. PP fiber twisted bunchy can be used for wall and roof of the tunnel and mine.
3. PP fiber twisted bunchy can be used for dam, river, bridge pier, dock and military protection facilities.
PP Fiber Twisted Bunchy 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.
2. Length:
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 PP fiber mesh form with the volume ratio of 1:1(0.9kg fiber-mesh to 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 com-pletely 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.
