First, the product description Introduction
The fiber is made of polypropylene as a raw material and processed through special modification and corrugating process. It has the advantages of acid and alkali corrosion resistance, high strength, easy dispersion, easy construction, no damage to vehicles and pavement after mixing, and no special maintenance. It can replace steel fiber for strengthening crack prevention in cement concrete, and because of special The corrugated cross-section shape has good bonding performance with concrete and strong grip strength.

Third, the use of instructions
1. Dosage: 3kg per cubic meter of concrete
2, length selection: general enhanced anti-crack 50mm, 19mm in shotcrete
3, sleep ratio design: Under normal circumstances, it is not necessary to change the grade ratio parameter of concrete. Considering the crack resistance performance requirements of concrete, it can be used in combination with polypropylene mesh fiber in a volume ratio of 1:1 (0.9kg mesh fiber is blended in each concrete).
4. Mixer selection: Select the double-shaft horizontal forced mixer.
5. Feeding and stirring process: first put the crushed stone, then put the fiber into it, then put it into the sand and stir it for 2 minutes to make the fiber fully open, then put the cement and water into the normal process and stir it evenly. It can also be applied in the order of conventional process input, but the mixing and stirring time should be no less than 4 minutes, and the vibration time should be appropriately extended to make the fibers fully mixed.
6. Forming and curing: No special requirements, the shaking time can be extended for about 30 seconds as appropriate. When the surface is cleaned, it should be slightly passivated before the concrete surface is removed, so as to avoid the fiber, and the curing should still be carried out according to the requirements of ordinary concrete.
7, packaging form: 1.5kg / bag, can be sub-package according to user requirements
Fourth, economic economy
Compared with steel fiber, plastic corrugated fiber has the advantages of corrosion resistance, less wear and tear, and a 50% reduction in the volume of the same volume.
