Bridge deck net crack treatment
I. Introduction of Bridge deck net crack treatment !
Deck concrete repair material (QM type) is a high-tech strength and good toughness
rapid repair material, ideal material suitable for highway, national, provincial,
municipal roads rapid repair of the bridge. The Department of Science and
Technology in Henan can bridge cement potholes Treatment, Treatment cement
pavement crack, crack Treatment bridge deck Treatment potholes, broken concrete
bridge expansion joints, potholes, cracks quickly repair areas with core technology!
Realized 1h fast open traffic!
2. product characteristics of Bridge deck net crack treatment :
a: fast recovery of traffic: for high-speed, national, provincial, municipal, airports and
other transportation can be achieved 1 hours.
b: high compressive strength: 1h more than 25Mpa, 2h more than 35Mpa, 1d more
than 60Mpa, 28d more than 80Mpa.
c: high flexural strength: 1h greater than 5Mpa, 2h greater than 7.5Mpa, 1d more than
10Mpa, 28d more than 11Mpa.
d: good adhesion properties: bond pull strength reaches 2.8Mpa, to solve the
traditional material bond is not strong or problems can easily lead hollowing cracks.
e: the product toughness and impact resistance: 5-10 times that of ordinary concrete.
f: the thermal expansion coefficient: basically consistent with the primary concrete.
g no shrinkage cracks: between the original concrete and no shrinkage cracks after
solidification.
h: frost and salt corrosion: cold-resistant, corrosion-resistant sulfate, non-toxic,
non-corrosive.
