QM Bridge expansion joint repair materials
1, product introduction
QM bRIdge expansion joint rapid repair materials is a new high-tech repair materials for the concrete.it suit for repair the bridge expansion,bridge
QM type bridge deck concrete repair material is a kind of one-component special repair material, The construction of the materials is simple, high
strength, good toughness and cohesive force strong, Not broken and not fall off under the
high speed, high pressure, impact of traffic condition.
Scope of application:
1, Bridge surface layer pothole, crack rapid repair;
2, Bridge expansion joint concrete crushing, hole, crack rapid repair ;
3, Expressway, national highway, provincial highway, airport, municipal engineering, tunnel concrete pavement pit, serious cracks, voids, fracture crack etc. severe damage rapid repairing;
Product advantage:
1, Achieve rapid restore traffic in 1-2 hours.
2, High compressive strength: more than 25 mpa in 1 h, more than 35 mpa in 2 h, more than 60 mpa in 1 day.
3 ,High flexural strength: more than 5 Mpa in 1 h, more than 7.5 Mpa in 2 hour, more than 10 Mpa in 1 day.
4 Cohesive force strong: not appear the empty drum or crack.
5, Product toughness and shock resistance: 5 to 10 times than ordinary concrete.
6, Coefficient of heat bilges cold shrink, consistent with the grass-roots level concrete.
7, No drying shrinkage crack: no the drying shrinkage with the original concrete after solidification
8, Antifreeze and corrosion resistance: resistance to freezing, sulphate corrosion resistance, non-toxic, non-corrosive.
