Offshore wind turbine grout
A two-grade cementitious underwater anti-dispersion grout for offshore wind foundation cavities and submerged load-transfer zones. CBGM-50 and CBGM-70 provide separate compressive-strength routes while sharing high-flow, zero-bleeding and reinforcement-protection requirements.

Technical data
“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 - initial / 30 min | ≥290 / ≥260 mm | — | Supplied offshore-wind manual; both grades |
| CBGM-50 compressive strength - 1 / 3 / 28 days | ≥15 / ≥30 / ≥50 MPa | — | Supplied offshore-wind manual |
| CBGM-70 compressive strength - 1 / 3 / 28 days | ≥20 / ≥40 / ≥70 MPa | — | Supplied offshore-wind manual |
| Bleeding | 0% | — | Supplied offshore-wind manual; both grades |
| Corrosion effect on underwater reinforcement | None | — | Published criterion in the supplied offshore-wind manual; confirm the applicable test method |
| Chloride ion content | <1.5% | — | Supplied offshore-wind manual; confirm the calculation basis in the current controlled TDS |
| Vertical expansion | — | Not published hereCurrent controlled TDS required | The source table is visually ambiguous; no value is inferred |
