Dosage of polypropylene staple fiber
1) anti-cracking putty
Use 2-3 mm fiber, add polypropylene fiber 0.5 -1.0 kg in 1 ton anti-cracking putty. Can use longer length or slightly increase dosage of fiber according to actual use.
(2) Base mortar( aggregate less than 1mm) 6 and 12 mm fiber, add 3 g fiber for 1kg cement . General dry mixing firstly and then adding water. When cement under 400 kg in per cubic meter mortar , the minimum usage is 1.2 kg for each cubic fiber; When the cement content is more than 400 kg, increase 3 g fiber for each increased 1 kg cement .
3) Normal concrete for structure, precast and road brick: Using 19 mm fiber, cement content at 350 kg in 1 cbm concrete, the minimum usage is 0.9 kg for each cbm concrete; when cement more than 350 kg in 1 cbm concrete, increase 2g fiber for each increased 1 kg cement.
1. Anti-crack application for industrial and civilian construction, and impermeable and thermal mortar 2. The concrete placement engineering with high requirements on impermeability and impact resistance such as concrete-faced rockfill dam, spillway and deflector hole, etc. in the hydraulic and hydro-power engineering. 3. Various precast concrete products. 4. Concrete for speedway, bridge, tunnel and airport pavement, etc. 5. Chemical plants, etc. with high requirement on resistance to alkalis and chemical corrosion.
