CBGM-125 is a cementitious grout engineered for offshore wind turbine foundations, combining ultra-high strength with long-term shrinkage compensation.
Summary Benefits at a Glance:
Ultra-high compressive strength (125 MPa standard, 160 MPa optional)
Superior fluidity and self-compacting properties
Shrinkage-compensated, ensuring crack resistance
Excellent durability in aggressive marine environments
Product Introduction
CBGM-125 High-Strength Non-Shrinking Grout is a cementitious material developed for offshore wind turbine foundation grouting. By using advanced nano-modified reinforcement technology, the grout combines excellent flowability, ultra-high strength, and long-term durability. It ensures reliable structural performance in harsh marine conditions, with stable shrinkage compensation that prevents cracking and enhances bonding between steel and concrete.
CBGM-125 is available in two grades:
Standard Type: Compressive strength ≥125 MPa at 28 days
Optional Type: Extended compressive strength ≥160 MPa at 4 months
