It can rapid-hardening,self-leveling,reinforce the equipment.

Polar Bear Non-Shrink grouting material is blended through a special procedure by specially selected cementitious material, carefully selected fine aggregate and admixture. It owns the characteristics of high flow, non-shrinkage, early strength and high strength. Functionally they are divided into two categories include four products: High strength -I,-II; Extra early strength-I, -II

Properties:

Double expansion in plastic and hardened state, compensate the dry shrinkage, ensure the fixed combination between steel-back plane and concrete base, efficiently transmit the load carrying into the base.High early strength: this material is obtained by special cement as its basic material, it is suitable for urgent repair and accelerators construction under negative temperature environment.High fluidity.Easily used, only mixed with water on site, easily pumped.Durability: High final strength, excellent impermeability and corrosion resistance, ensure accuracy of equipment setting.Working environment: this material can be operated in a negative temperature environment with a rapidly increased strength.

7. Non-chloride: no harm for equipment or armature reinforcement.
