crack filler for concrete drive way
how do you repair cracks and chips in a concrete driveway? pls check follow repair process:
For concrete crack on drive way, we suggest you use SC type concrete repair material.
Because:
1) SC concrete repair material is mainly repair for: concrete slab corner crack, serious crack,
edge failure, pothole and depression etc.
2)SC type concrete repair material have follow advantage:
Rapid repair, 1 hour open to traffic
Good adhesion,Compressive & Flexural strength is 2 times of normal concrete.
Toughness & impact resistance strength is 5-8 times of normal concrete.
Frost resistant & sulphate corrosion resistant, non- toxic, non-corrosive.
Beautiful,uniform color,Expansion shrinkage coefficient is basically same.
Simple & rapid construction,Can be used as first-aid repair materials in damp environment.
3)Testing data of 28 days:
Test items | Unit | Technical requirement | Test result | Individual conclusion | |
Setting time | Initial setting | Min | ≥20 | 25 | Meet requirement |
Final setting | ≤60 | 35 | |||
Compressive strength | 4h | Mpa | ≥20 | 33.0 | Meet requirement |
1d | ≥40 | 66.1 | |||
28d | ≥50 | 90.5 | |||
Pull strength | 28d | Mpa | ≥2.0 | 2.8 | Meet requirement |
Expansion rate | 28d | / | 0.00%-0.1% | 0.01% | Meet requirement |
4)Compare of before and after repaired:
5)Benefit analysis:
SC cement road repair material have super strong compressive strength,
adhesion strength and durability.Rapid,efficient repair to disease area.after completed repair,
1 h can open to traffic.
Compared with cement road paving asphalt, this method have 4 big advantage:
1)Can save some money of repairing in earlier stage.
2)Repair service life is long
3)Road bearing capacity is high
4)Adhesion force is far more than asphalt, save time and labour in later period maintenance, don't need repair again and again.
