40mm PP Fiber Twisted Bunchy 500T Form For Concrete Reinforcement
PP Fiber Twisted Bunchy Introduction:
Briture pp Fiber Twisted Bunchy 500T is using PP/PE polymer as its raw material, produced the rough surface treatment by special paralle thread extruding & twsting process. thas horbreak strength,beter dispersion and strong combining ability, will be widely used to instead of steel fiber to reinforce the cement concrete and crack-esistant.
PP Fiber Twisted Bunchy Ration design of the fibre concrete:
Generally the recommended amount to add to the concrete is more than 2.7kg per som (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.
PP Fiber Twisted Bunchy 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 sgm of cement concrete).
PP Fiber Twisted Bunchy Mixer Adoption:
Double-axle horizontal compelling mixer is priority
PP Fiber Twisted Bunchy 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
PP Fiber Twisted Bunchy Shaping & Maintenance:
There is no special requirement, may along the vibrating time for 30s, The maintenance of the fibre concrete should be done same asl the normal concrete.
PP Fiber Twisted Bunchy Application:
1.Concrete reinforcement
2.Industrial Floor
