CBGM-low-temperature grout

◆ Normal construction at ambient temperature of -15℃ to -20℃;
◆ High flow state, no bleeding, anti rust, ensure consistent final physical performance and prevent blocking of grouting pump
◆ No vibration and slight expansion;
◆ It can be pumped or injected into complex areas or areas difficult to access by conventional grouting methods.
◆ Excellent fatigue resistance
◆ Ultra high compressive strength: exceeding the highest level of EN206, such as C100/115.
