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, Extra early strength.
GENERAL
Application:
1, the secondary grouting equipment installation
2, steel structure column base installation
3, all kinds of machinery electrical equipment flow grouting pad iron free installation
4, anchor bolt anchoring, column base grouting and batholith grouting
5, frame structure joints of anchor reinforcement reinforcement, bridge joint 6, the post-tensioned prefabricated seam grouting, prestressed concrete Bridges
7, concrete beam, slab, column, wall body and foundation reinforcement and repair
Advantage:
Evaporated enlargement system compensates for shrinkage and settlement within the plastic stat.
•No bronze iron content to cause staining
•Pre-packed material overcomes onsite batching variations
•Develops high early strength while not the employment of chlorides
•High final strength make sure the sturdiness of the hardened grout
•Free flow ensures high level of contact with load bearing space
Technique characteristics:
1, early strength, high strength: equipment installation after three days to run the production.
2, their state, micro expansion: to ensure that equipment and close contact between foundation.
3, no rust, oil resistance, permeability.
4, durability: 2 million times of fatigue experiment, 50 times of freeze-thaw cycle test intensity has no obvious change.
5, good weatherability and 40 ℃ ~ 600 ℃ using long-term security.
Storage:
this product unopened, appropriate packaging in a dry, cool, ventilated place. Under normal conditions of storage and transport, guarantee period is 12 months.
