German Chongqing New Asia polymer repair mortar factory 13,311,126,842 German Chongqing New Asia polymer repair mortar factory 13,311,126,842 German Chongqing New Asia polymer repair mortar factory 13,311,126,842 German Chongqing New Asia polymer repair mortar manufacturers 13311126842 CGM-320B polymer repair mortar CGM-320B is designed for high-grade surface repair of concrete structures and the development of one-component polymer repair mortar. The existing inorganic cementitious repair mortar high mortar strength characteristics, but also the polymer mortar toughness, crack resistance and excellent adhesion characteristics, especially for high-speed railway passenger line C50 and C55 beams over van orbit above board surface defect repair. I. Features 1. High Strength. The ultimate compressive strength of 60MPa reach more than fully meet C50 ~ C60 concrete surface repair. 2. The combination of strong and original concrete surface. Use it in combination with mortar interface agent adhesive tensile strength ≥3.0MPa above can be achieved by the effect of concrete surface damage. 3. waterproof, impermeability and weather resistance effect. 4. Can grass roots in wet and humid environment, construction, may be discontinued without conditions of partial repair. 5. Green, no harmful volatile substances. Second, the surface defects Applications 1. High-speed railway passenger dedicated van beams and boards and other high-grade orbit repair of concrete structures. Surface defects of concrete structures 2. Other high strength repair. Third, performance indicators compressive strength 1d (MPa) and flexural strength 1d (MPa) compressive strength 28d (MPa) and flexural strength 28d (MPa) impermeability strength 28d (MPa) and the interface agent with a tensile bond strength 28d (MPa) ≥30 ≥4 ≥60 ≥8.0 ≥1.5 ≥2.5 Fourth, the basic performance of 1, compressive and flexural strength taking into account the design strength of the high-speed railway construction in prestressed concrete beam van for C50 (actual strength ≥60 MPa), the design strength of the concrete track slab is C55 ~ 60 (actual strength is also more than 60 MPa), 2, n-pull adhesion strength repair mortar mixed with a solid powder, so its positive pull adhesion strength 1.5MPa or so. Taking into account the practical requirements of high-speed rail repair mortar to a dedicated interface agent used in conjunction with positive pull the adhesive strength of up to 2.5MPa or more, the product of internal control indicators ≥2.5MPa. Fifth, use 1. Van beams and track defects surface of the plate clean. Excluding peeling, loose, cellular, and corrosion deterioration of concrete and rinse with water; 2. Add water and stir. Amount of water is 13 to 15% (by weight) and mechanical stirring (slow stirring) for 3-5 minutes. 3. Brushing dedicated interface agent. Applying a layer of the patch face special interface agent (emulsion). The interface agent if they had each brush again with the brush, brush interface agent per kg generally 3 to 5 meters. 4. Immediately after brushing interface agent with a spatula marinated repair mortar with a beat wipe repair surface. General repair layer thickness of not more than 30mm, the pressure of not more than 10mm suitable wiping every time, until the surface layer dry before the top layer of the construction. Self-leveling high-strength polymers may also be formulated repair mortar 4. Upon completion of the exposed surface of the mortar damp curing for 7 days (see concrete curing system) according to customer requirements, and then converted to dry to support 21 days, you can meet the design strength.
