Type U- non shrinkage high strength grouting
material
Features
· Non-bleeding. The fluidity is still better in the
condition of lower ratio of water to cement.
The gap can be fully filled.
· High early strength, high strength. The equipment can be finished
to install in 1~3 days.
· Having slight expansion; Non-shrinkage; high bond strength;
Gripping force with reinforcing
steel bar at 28 days is more than 6 Mpa.
· Non-aging. Non -corrosive to reinforcing steel bar
Application
· Grouting the anchor bolts and the base of large
sized equipments and precision instruments.
· Grouting the joint between steel construct and base
· Grouting the post-tensioned prestressed reinforcement
· Reinforcing the beam and column
· Building-in the construction joint of subway, tunnel and underground
construction
