1) Dosage: more than 3kg/cubic meter of concrete.
2) Length: 36 MM for general crack level, no more than 25 MM for shotcrete,
best use no more than 35 MM.
3) Mix design: In general, no need change the ratio parameters of concrete.
Considering the concrete anti-cracking performance requirements, can add 0.9 kg mono-filament
fiber per square concrete.
4) Instructions: crushed stones, fibers and sands are put into the mixer in succession.
After string for two minutes, fiber will fully spread and then add cement and water and stir normally.
The addition of materials can be put into as usual, but the stirring time should be properly prolonged to more than 4 minutes to make fiber completely mixed.
5) Forming conservation: Conservation can be based upon the requirement of ordinary concrete.
No special requirement, tape time can be extended for 30 seconds according to actual situation.
In order not to bring out fiber, plastering should be carried out after the concrete surface
passivation slightly.
