Non-Shrink grouting material

Polar Bear Non-Shrink grouting material is blended through aspecial procedure by specially selected cementitious material,carefully selected fine aggregate and admixture. It owns thecharacteristics of high flow, non-shrinkage, early strength andhigh strength. Functionally they are divided into two categoriesinclude four products: High strength, Extra earlystrength. Properties1.Double expansion inplastic and hardened state, compensate the dry shrinkage, ensurethe fixed combination between steel-back plane and concrete base,efficiently transmit the load carrying into the base.2. High earlystrength: this material is obtained by special cement as its basicmaterial, it is suitable for urgent repair and acceleratorsconstruction under negative temperature environment.3.Highfluidity.4.Easily used, only mixed with water on site, easilypumped.5.Durability: High final strength, excellent impermeabilityand corrosion resistance, ensure accuracy of equipmentsetting.6.Working environment: this material can be operated in anegative temperature environment with a rapidly increasedstrength.7. Non-chloride: no harm for equipment or armaturereinforcement Uses:1. Heavy equipment, Highprecision grinder.2. Erection Engineering of Structural steel3.Grouting to column foundation, pile foundation and Rock foundationto fixation.4. Anchoring of frame structure joint5. Repair to thehoney-comb and holes of reinforced concrete structure6. Repair& Reinforcement to concretestructure..   TechnicalData (test in standard lab)
