Deck crack repair material, the Department can bridge deck cracks

 How do concrete pavement from the sand of the road has been completed 15 days of pouring the deck crack repair factory, very serious situation from the sand, do not know the quality of concrete problem or did not take after the construction of conservation issues, and now how to solve, neighborhoods solution : BC-type patch treatment agent is a high permeability aqueous formulation. The major components of organic and inorganic silicon-based compound, and a small amount of the crystallization promoter. Designed for existing concrete floor due to poor construction, impatience wear, lower strength, resulting from the sand (Sand) and developed. This product is sprayed directly on the concrete surface, penetrate into the interior of concrete, cement hydration reaction activation, the role of silicide bridge cracks in concrete in a free state, such as lime particles will form a granite-hard crystals, resulting in a clean, compact whole, effectively improve the strength of the concrete surface, density and wear resistance. Extend the service life of concrete floors for more than 10 years. At the same time does not affect the use of the existing ground. Advantages: simple construction, low cost, short time, the effect is significant. Use: 1) Surface foundry due to insufficient curing or low cement content in concrete caused by dust from the ground. 2) loose dust from the surface of the old concrete or masonry surfaces. 3) the need for surface sealing to prevent oil or grease penetration play ground cement concrete pavement repair materials which cement concrete pavement patching material 2.1 BC BC cement pavement repair materials cement pavement crack repair material repair materials can be classified according to their function high modulus and low modulus reinforcement material sealing material. After curing the former has high strength and stiffness, the latter has a greater flexibility. When the need reinforcement, the choice of high modulus reinforcement materials, "live seam" Crack a class, it is desirable that the use of low-modulus material. High modulus epoxy crack repair materials, phenolic and modified phenolic resin adhesive; low modulus polyurethane closed material, alkenes, rubber, adhesives, such as asphalt. (1) QM-type bridge deck concrete repair concrete repair material QM type of cement concrete pavement patching material commonly used in epoxy resin material are mostly glycidyl type, commonly used bisphenol ring by polyphenol and polyols prepared epoxy resins, epoxy resins such rigidity, small ductile, brittle deck crack repair material with the old concrete bonding interface is easy to produce stress concentration and cracking. And after the epoxy resin modified, while maintaining a high strength, strong adhesion advantages, but also through the modification reduces the brittleness and improve the toughness, the most important category for cement concrete pavement crack repair is polysulfide change epoxy grout material. (2) SC SC cement pavement repair materials cement pavement repair materials with flexible molecular chains, vibration resistance and anti-fatigue properties are very good, in addition to its good low temperature resistance, suitable for use in a variety of natural temperature. One category of the earlier polyurethane is a polyisocyanate, its high bond strength, can react chemically with the material to be adsorbed on the cement surface and surface water hydrous oxides, or on the surface of the adhesive is alkaline self-assembled, at the interface. Deck crack repair material, the Department can bridge deck cracks can be provided by the Department of Road and Bridge Technology Co., Ltd., Henan. The Department of Science and Technology Co., Ltd.
