How to Caulk and Seal Cracks in a Concrete Driveway
1.Applied range:
Highway,national road,provincial road,airport,municipal engineering and tunnel
Serious disease such as concrete plate fracture,serious crack,edge failure and pothole
2.Detail feature:
Achieved 1--2 h rapid open to traffic.
High compressive strength:2h>33Mpa,1d >60Mpa,meet requirement of rapid repair strength.
Good adhesion: Have super adhesion force with original concrete.
Good anti-crack property: Adapt to deformation of concrete base, and don't crack or fall off.
Good toughness: it is 5-8 times of normal concrete.
Expansion shrinkage coefficient is basically same with base course concrete.
Can be used in damp base course and damp environment as first-aid repair materials.
Simple and rapid construction.
3.Technical parameter:
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 |
4.Quality control:
5.Construction process:
Joint-cutting
Chiseling
Washing
Mixing material
Repairing
Curing
6.Matters needing attention:
1)This repair material is of early type material, operation time is within 15 minutes, It can prolong
operation time as per user's request. Strictly prohibited use hardened mortar.
2)Add clean diameter ≤30㎜ continuous graded gravel aggregate,ratio is 50%.
3)In summer, Already repaired area surface should be prevented exposure.
The plastic film can be covered in repaired area surface.
4)It should pay attention to heat preservation and maintenance when winter.Can adopt hot water to stir, and cap rock wool quilt to keep warm. It can't construct when temperature below 5℃, wind power greater than 5 grade or rainy days.
