MasterFlow 9400: Ultra-high strength, cement based grout for onshore wind turbine installations

MasterFlow 9400, Ultra-high strength, cement based grout for onshore wind turbine installations

MasterFlow 9400 is a shrinkage compensated, cement based grout which when mixed with water, produces a homogeneous, flowable and pumpable grout with exceptionally high early and final strength and modulus. The product exhibits increased fatigue. Latest best binder packing models and applied nanotechnology produces a grout with superior technical performance, exceptional rheological properties, and uniquely, extended open times.

MasterFlow 9400 features and benefits

• Ultra-high compressive strength: above highest class of EN206, i.e. > C100/115.
• Ultra-high modulus for exceptional stiffening properties.
• Excellent fatigue resistance.
• Quick return to service and removal of temporary supports due to high early strength build-up. ≥ 50 MPa @ 24hrs at 20°C.
• No segregation or bleeding to ensure consistent final physical performance and to prevent pump blockages.
• Extended pot life of ≥ 2 hours.
• Can be pumped into complex areas or areas inaccessible to conventional grouting methods.
• Dust reduced for ease of handling.
• Cement based.
• Low chromate.
