Ground the hollowing cement grouting material 
 Use this product on the concrete surface due to various causes cracks to repair. To dramatically improve the concrete abrasion resistance, toughness, impact resistance, impermeability, resistance to chemical erosion, anti-carbonation, to extend the service life of concrete. 
 Features 
 A. Condensation hardening and strength development of fast, high strength concrete base and crack wall bond. 
 (2) The product has excellent mobility and moisture retention, to be able to successfully penetrate the fine cracks, the effective crack repair purposes. 
 (3) of this product with better compensation shrinkage, toughness, impact resistance and abrasion resistance, high temperature resistance and resistance to freeze-thaw cycling performance and excellent durability. 
 4 This product is no corrosion of the concrete internal reinforcement. 
 Applications 
 (1) This product is widely used in concrete pavement, bridge deck crack repair. 
 2 This product can also be used post-tensioned prestressed steel wire casing grouting; steel and concrete fixed secondary grouting; bolt seat secondary grouting of large equipment or sophisticated equipment; subway, tunnel and underground engineering, reverse play construction joints mounted; engineering repairs, concrete beams, plates, columns to strengthen reinforced; wear resistance, corrosion resistance, erosion resistance, self-leveling the ground.
