step 6: repair finished
More information of SC type concrete repair material:
1)rapid repair cracks, potholes, corner cracking, edge failure etc in concrete road,driveway,sidewalk,garage,basement,airport runway etc. 1 hour open to traffic.
2)Four big core advantage:
Practical performance: Fast and convenient repair, 2h can restore traffic
Adhesion performance: Adhesion force≥2.8, don't break and fall off under heavy load
Durable performance:Compression resistance,wear-resisting,waterproof anti-freeze,hydrochloric acid corrosion resistance
Higher strength,beautiful,color of repaired surface is closed to original concrete road,
suitable for all kinds of weather.
3)Testing data:
Test items | Unit | Technical requirement | Test result | Individual conclusion | |
Setting time | Initial setting | Min | ≥20 | 25 | Meet requirement |
Final setting | ≤60 | 35 | |||
Compressive strength | 2h | Mpa | ≥20 | 33.0 | Meet requirement |
1d | ≥40 | 66.1 | |||
28d | ≥50 | 90.5 | |||
Pulling strength | 28d | Mpa | ≥2.0 | 2.8 | Meet requirement |
Expansion rate | 28d | / | 0.00%-0.1% | 0.01% | Meet requirement |
