NSG 50
Product Description
Non-Shrinkage Grout-50 can be mixed to a fluid, flowable, or plastic consistency requiring only the addition of clean water. Total shrinkage compensation, which provides a maximum bearing surface for the greatest overall support.
Features
- Rapid power increase to reduce turnaround time for equipment installation
- Excellent working time at high ambient temperatures.
- Economical, large amounts of grout can be mixed and handled.
- Non-corrosive, non-chloride, non-metallic
- Excellent resistance to freeze-thaw cycling
- High strength for maximum load bearing
Technical Analysis:
Compression strength
Compressive strength (after 1 days) - > 15.0 mpa
Compressive strength (after 3 days) - > 30.0 mpa
Compressive strength (after 7 days) - > 40.0 mpa
Compressive strength (after 28 days) - > 50.0 mpa
How To Apply:
- Clean and pre-wet any surface free of grease, oil, or loose particles.
- Place grout in a manner that avoids air entrapment. Be careful not to overwork the grout and avoid segregation.
- Make vent holes wherever they are needed.
- A vibrator, rod, chain, or trowel may be used to assist in consolidating the grout and eliminating air voids.
- Forms should be sealed to prevent water or grout loss.
- Whenever possible, bolt holes should be grouted first.
- Placement and consolidation should be continuous for any one section of the grout.
- Forms can be removed, and excess grout should be trimmed from surfaces and edges after the grout has hardened to its initial set.
Thickness
Thickness is critical; the minimum application thickness is 1/2 inches (13 mm) and the maximum is 4 inches (100 mm).
Curing
- Keep the patch damp after the first 24 hours in the final setting stage to prevent excessive loss of water in dry or humid conditions.
- Cover the surface with wet burlap or a towel overnight to retain moisture.
- One can even use fog spray at this stage.
- Remove the cover, leave it up for 24 hours, and let the air cure.
- Damp curing is not required while repairing small cracks.
