3. About product
SC Type concrete repair material specially aiming at concrete disease,such as concreta cracks,potholes,surface fracture,etc.
With high bonding strength and high compressive strength, the concrete disease won't appear fall off and broken after repair,even if the thin layer repair 1-2mm.
The core advantage of this product is rapid initial setting time,it can be finished in 25 min.So the traffic canbe opened in 1 hour.
4. Core advantages
1) 1 hour can open traffic
2) high compressive strength(check the technology index at below)
3) high bonding strength,achieving thin layer rapair
5. construction process
6. High standard technology
