Cold-weather wind turbine grout
CBGM Antifreeze Wind Turbine Foundation Grout
A low-temperature, high-strength, non-shrink grout for winter wind farm construction and cold-region baseplate or anchor-cage placement. The published manual specifies flow at sub-zero conditioning and strength development under a defined negative-temperature curing route.
Recommended uses
Where this material fits.
- Winter installation of onshore wind turbines
- Cold-region baseplates and anchor cages
- High-altitude and severe-climate wind farms
- Temperature-controlled emergency grouting
Performance benefits
What the system is designed to deliver.
- Manual positions the system for work down to -20°C
- Flow requirements stated at -5°C and 8°C
- Zero bleeding requirement
- Low-temperature strength route stated separately from standard curing
Technical data
Requirements and reported values, separated.
“Requirement” is the stated acceptance threshold or range. “Actual result”, “typical value” and “published value” are not guaranteed minima unless the requirement column says so. Final acceptance must follow the approved TDS, report, test method and project conditions.
| Property | Minimum / specified requirement | Typical / reported value | Test method / source |
|---|---|---|---|
| Flowability at -5°C - initial / 30 min | ≥300 / ≥260 mm | — | Supplied Chinese product manual; verify in the approved cold-weather method statement |
| Flowability at 8°C - initial / 30 min | ≥300 / ≥260 mm | — | Supplied Chinese product manual |
| Negative-temperature compressive strength - 12 h / 1 d / 3 d | ≥25 / ≥35 / ≥60 MPa | — | Supplied Chinese product manual; follow the stated conditioning route |
| Negative-temperature compressive strength - 7 d plus 21 d | ≥85 MPa | — | Supplied Chinese product manual |
| 3-hour vertical expansion | 0.02-2.0% | — | Supplied Chinese product manual |
| 24-hour minus 3-hour expansion | 0.02-0.40% | — | Supplied Chinese product manual |
| 28-day dry shrinkage | ≤0.045% | — | Supplied Chinese product manual |
| Chloride ion content | ≤0.03% | — | Supplied Chinese product manual |
| Bleeding | 0% | — | Supplied Chinese product manual |
