CSA Non-shrink Grouting Material

الوصف

CSA Non-shrink Grouting Material is a reinforce material for concrete,with advantages of non shrinkage,high fluidity,high early strength,double expansion,it can be used as filling grout, repair material for concrete reinforcement and crack resistance of construction.Functionally it can be divided into two catalogs include four products:High strength*1,*2;extra early strength*1,*2.

Characteristic:
1.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.
2.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.
3.High fluidity.
4.Easily used, only mixed with water on site, easily pumped.
5.Durability: High final strength, excellent impermeability and corrosion resistance, ensure accuracy of equipment setting.
6.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 reinforcementTechnical Data

Uses:
1. Heavy equipment, High precision grinder.
2. Erection Engineering of Structural steel.
3. Grouting to column foundation, pile foundation and Rock foundation to fixation.
4. Anchoring of frame structure joint.
5. Repair to the honey-comb and holes of reinforced concrete structure.
6. Repair & Reinforcement to concrete structure.
 
Using methods:
Foundation treatment:

1. Scaling and cleaning will be applied to the concrete base
2. Solvent should be adopted to clear up the rust and oil on the bottom (the surface that will contact grout) of equipment
3. Molding board joint should be treated well to ensure grouting material wont leak.
4. Before grouting ,keep the concrete bed wet without water.

1. Mixed grouting material should be used out before lost its fluidity.
2. Grouting should begin from one side intend to avoid release entrapped air.
3. Coordinating mixing ability with grouting speed well for continuous operating.
4. Grouting surface should be a little higher than designed peak. In case of not need this part, it can remove before hardening.
