cement bridge expansion joint repair product
Product introduction
QM type bridge deck concrete repair material is gathered from henan can bridge science and technology research and development production of a kind of high strength and toughness good high-tech asphalt rapid repairing materials.Suitable for expressway, national highway, provincial, municipal bridge deck crack treatment, bridge hole treatment, bridge expansion joints of concrete crushing, hole, crack repair quickly.Company has the core technology, to realize the fast restored 1 h, 2 h!Resolve the problems of bridge deck construction lead to traffic jams.Meet the high grade highway, national highway, provincial highway bridge repair the requirement of high quality, durability requirements.
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, The surfacing layer hole, crack the rapid repair of the surfacing layer;
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
