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. The fiber has greater effects on concrete with active compound materials, such as silicon ash, coal powder, ground slag, and zeolite powder.
A double-axle horizontal mixer is preferable; a self-dropping cylinder mixer is also acceptable.
Crushed stones, fibers, and sand are fed into the mixer sequentially. After stirring for about 2-3 minutes, the fiber will fully spread. Then add cement and water, and stir again as per the normal process. The addition of materials can also be performed as usual, but the stirring time should be extended to more than 4 minutes to ensure the fiber is completely dispersed.
Here is s a quick, back‑of‑the‑envelope estimate—based on a few reasonable assumptions and typical U.S. labor‑rate ranges—of the approximate added labor cost per cubic meter / cubic yard when polypropylene mesh fibers are mixed 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.
