How to repair large cracks in concrete driveway?
Concrete repair material 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 | 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 |
repair advantage:
1.Achieve 1h rapid open traffic.
2.High bond strength, really achieve don't break and take off.
3.High compressive and flexural strength, at the same time, good toughness.
4.Average life more than 3 years.
5.Radical cure serous cracks, restore original plate strength.
6.Joint tightly after repair,no dry shrinkage cracks, and color is same as original road surface.
Benefit analysis:
SC concrete 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.
