1.Product Introduction
SC type concrete road repair material is a kind of single component rapid repair material.The material have sample construction, 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 Range
1)Concrete road slab fracture, serious cracks, edge failure, potholes etc.
2)Bridge deck pavement potholes and cracks.
3)Bridge expansion joint concrete potholes and cracks.
3.Core Advantage
1)Achieved 1--2 h rapid open to traffic.
2)High compressive strength.
3) Good adhesion
4) Expansion shrinkage coefficient is basically same with base course concrete.
