How t o repair concrete pothole?
One.Brief introduction
SC Type concrete repair material is manufactured by Henan Huineng road and bridge technology co,.ltd. our company master the core technology and specializes in concrete repair material for many years. SC Type cncrete repair material aiming at solving seroius concrete desiease such as wide cracks, deep pothle etc. It can be widely used in highway, national road, provincial road, bridge deck etc. The product has many advantages, such as rapid setting,high compressive strength, good adhesion, anti-crack.
Two. Product Applications Scenarios
1)Highways, national roads, provincial roads, airports, municipal engineering and tunnel.
2)Concrete road slab fracture, serious cracks, edge failure, potholes etc.
3)Bridge deck pavement potholes and cracks.
4)Bridge expansion joint concrete potholes and cracks.
5)Concrete road depression.
6)High-speed railways, water conservancy, wharf, parking lots and gas station.
Three.Product Competitiveness
1.1 hour open traffic
2. High compressive strength:2h>33Mpa,1d >60Mpa,meet requirement of rapid repair strength.
3.Good adhesion: Have super adhesion force with original concrete.
4.Good anti-crack property: Adapt to deformation of concrete base, and don't crack or fall off.
5.Good toughness: it is 5-8 times of normal concrete.
6.Expansion shrinkage coefficient is basically same with base course concrete.
