Concrete bridge deck hole rapid repair mortar
QM type bridge deck concrete repair material is a kind of one-component special repair material, the material of construction is simple, high strength, good toughness and cohesive force strong, at high speed, high pressure, impact of traffic condition is not broken and not fall off.
Scope of application:
1,Can rapid repair the cement surface crack,hole and so on ;
2, Bridge expansion joint concrete crushing, hole, crack repair quickly;
3, Expressway, national highway, provincial highway, airport, municipal engineering, tunnel concrete pavement pit, serious cracks, voids, fracture and other severe damage of rapid repairing;
Product advantage:
1, Achieve rapid opening traffic 1-2 hours.
2, High compressive strength: more than 25 mpa. 1 h, 2 h is greater than 35 mpa, 1 d greater than 60 mpa.
3 High flexural strength: 1 h is more than 5 Mpa, 2 h is greater than 7.5 Mpa, 1 d is greater than 10 Mpa.
4 Cohesive force strong, does not result in an empty drum or crack.
5, Product toughness and shock resistance: 5 to 10 times that of ordinary concrete.
6, Coefficient of heat bilges cold shrink, and concrete at the grass-roots level.
7, Swear crack: after solidification and the original concrete crack between swear.
8, Antifreeze salt corrosion resistance: resistance to freezing, sulphate corrosion resistance, non-toxic, non-corrosive.
The construction process:
Traffic control→ identify→lineation→joint-cutting→Chisel except→clean→scour→protection
→Mixing materials→repatching→joint-cutting→maintenance
