Generally, the proper length of the fiber added to concrete is 18mm, and for spray concrete, it is 12mm.
Usually, the proper amount of concrete is 0.9kg/m3; the waterproof layer of the bridge requires 1.20-1.8kg/m3; the spray concrete in the tunnel is also 1.8kg/m3. Fibers have greater effects on concrete when combined with active compounds such as silica ash, coal powder, ground slag, and zeolite powder.
A double-axle horizontal mixer is preferable; a self-dropping cylinder mixer is also acceptable.
Feed crushed stones, fibers, and sand into the mixer sequentially. After stirring for about 2-3 minutes, the fiber will be fully dispersed. Then add cement and water and stir again as usual. You can also add materials as usual, but extend the stirring time to more than 4 minutes to ensure the fiber is fully dispersed.
Here is a quick, back‑of‑the‑envelope estimate—based on a few reasonable assumptions and typical U.S. labor‑rate ranges—of the approximate additional labor cost per cubic meter/cubic yard when mixing polypropylene mesh fibers into concrete.
Extra labor time (per m³ of concrete) | Lower-end hourly labor rate | Typical hourly labor rate |
$30/hr | $40/h | |
Negligible impact:0 min | 0 | 0 |
Low impact:5 min | $2.50/m³ | $3.33/m³ |
Moderate impact:10 min | $5.00/m³ | $6.67/m³ |
Noted:
1. If the fibers are just mixed in dry and the pumping/placement goes smoothly,
It’s usually “low impact” or “negligible.”
2.Quick formula: added cost ($/m³) = (hourly rate ÷ 60) × extra minutes.
Conclusion: In most cases, adding mesh fibers won’t raise labor costs — or only adds a tiny bit.
As a leading polypropylene mesh fiber factory, we specialize in producing premium virgin PP fibers for the global construction market. We offer high-quality polypropylene mesh fiber in various lengths (such as 12mm and 18mm) to meet specific project requirements, from tunnel shotcrete to bridge deck overlays. Whether you are looking for a trusted PP mesh fiber manufacturer or a wholesale concrete fiber supplier with competitive factory pricing, XRT-MS is your ideal partner. Our advanced fibrillated design makes us a top-tier supplier of concrete reinforcement fibers, delivering easy-to-disperse solutions that minimize labor impact while maximizing engineering performance.
A: Yes. Polypropylene mesh fiber blocks early plastic microcracks fundamentally to prevent water seepage, spalling, and damage
caused by crack expansion, greatly lowering later maintenance frequency of pavement, floor, and tunnel, and cutting total long-
term project cost.
A: Ordinary monofilament PP fiber easily floats and distributes unevenly during mixing. Polypropylene mesh fiber is an integrated
mesh structure, split into millions of filaments evenly interspersed inside concrete after stirring, with much higher 3D
reinforcement density and better micro-crack control without floating mortar.
A: Polypropylene mesh fiber has excellent low-temperature toughness, maintaining stable tensile and dispersion performance
under -20℃ without brittle break during winter mixing & pouring. This polypropylene mesh fiber works steadily for cold-region
infrastructure and water conservancy projects.
A: 0.6/0.9/1.0kg/PE film bag or water-soluble bag, Carton or water-soluble carton, or plastic woven bag are okay.
