TWO. About our product
1.Brief introduction
SC type concrete repair mortar is researched independently by Henan Huineng Road And Bridge Technology Co.,Ltd.
Which have core technology in repairing concrete road potholes, broken corner and cracks. Achieving 1h-rapid open traffic.
The material have many advantages, such as: high strength, good toughness, super adhesion force, waterproof, anti-
freeze, seamless repair and small color with original concrete, it won't break and fall off under high speed and high voltage driving.
Fully meet high quality requirement of rapid repair for high grades roads, national roads, provincial roads and municipal roads.
2.Application
1).Highways, national road,provincial roads,airports, municipal engineering and tunnel.
2).Concrete road slab fracture,serious crack,edge failure,pothole etc.
3).Bridge deck pavement potholes and cracks.
4).High-speed railway,water conservancy,wharf,parking lots and gas station.
3. Core advantages
1).1hour open traffic.
2).High compressive and bonding strength.
3).Good adhesion:have supper adhesion force with original concrete.
4).Good anti-crack property: adapt to deformation of concrete base,don't crack or fall off.
5).Good toughness:it is 5-8 timed of normal concrete.
6).Expansion shrinkage coefficient is same with base course concrete.
7).Can be used in damp base course and damp environment as first-aid repair materials.
