54mm PP Twisted Bunchy Fiber Common Crack-Resistant Requirement
PP Twisted Bunchy Fiber Introtuction:
PP twisted bunchy fiber is a kind of concrete additive, using
polyolefin as raw material, its rough surface is processed by
special parallel thread extrusion and twisting process. It is often used to strengthen concrete instead of steel fiber
PP Twisted Bunchy Fiber Feature:
The pp twisted bunchy fiber which have high fracture strength, good
dispersion and strong binding force.
PP Twisted Bunchy Fiber Applying Instruction:
1. Mixing ratio: It is generally recommended that the concrete
content per square meter should be more than 2. 7kg (volume ratio
0.3%), and the reinforcement should be 5.5kg
2. Length: The usual crack resistance requires a fiber length of
54mm
3. As shown. Mix ratio: The proportion of concrete usually does not
change, in order to crack resistance requirements, it is
recommended that the polymer fiber and PP fiber mesh in the form of
1:1 volume ratio (per square meter of cement concrete 0.9kg fiber
mesh) used in combination.
4. Use: dual axis horizontal forced mixer preferred.
5. Mixing process: the gravel, fiber, sand in turn into the
blender. After the fiber is fully developed, add cement and water
and stir normally. The added material can be added in the same way
as ordinary concrete, but the mixing time needs to be extended
appropriately to ensure that the fibers are fully mixed.
6. Styling and maintenance: no special requirements, can be 30
seconds along the vibration time, the maintenance method is the
same with ordinary concrete.
