JS-GHPC corrosion admixture GHPC corrosion admixture (alias GHPC marine corrosion mineral admixtures) is a complex admixture, GB6566 "radionuclides in building materials" and JTJ275 "harbor engineering concrete structure corrosion technical specifications" standard requirements. The right amount of concrete incorporated into the harbor, with excellent crack resistance and impermeability, by increasing the density of concrete to resist salt corrosion chlorine, from the fundamental reaction mechanisms to prevent or slow play * salt and chloride corrosion effect to improve the durability of concrete is the solution of concrete due to shrinkage of harmful crack and shrink, leading to chloride ion penetration, water erosion and other problems and improve the durability of concrete structures harbor engineering high-quality materials. JS-GHPC performance indicators 1, the proportion of 28-30g / cm; 2, setting time: initial setting time, 45 minutes; the final setting of <10 hours; 3, the test limit expansion (within 10% mixed), seven days in water, 0.025%; the water 28 days 45Mpa; 5, resistance to chloride ion permeability (C) <1000; 6, can build self 0.2-0.7Mpa stress in reinforced concrete; 7, greatly improved the corrosion resistance of concrete in seawater corrosion resistance coefficient (K) ≥1.0%; 8, the appearance of shape, white powder-like material; 9, anti * Limit salt concentration: 15000ml / L; JS-GHPC use of concrete JS-GHPC harbor marine corrosion mineral admixture 1 can play a structural waterproof, long structure seamless construction, crack control and prevent penetration of chloride ions concrete, resistant to salt water corrosion and anti * salt erosion in five areas. 2, marine concrete structures or parts in direct contact with the water, such as: dock, berm, offshore oil drilling platform, cross-sea bridge piers, water channels. 3, can be used in the preparation of cracking impermeable concrete basement and coastal areas are waterproof, anti-corrosion requirements of the building. Such as basements, subways, tunnels, etc. 4, the preparation of shrinkage-compensating concrete can be used for marine massive concrete structures and require fewer joints remain bulky projects. 5, saline areas infrastructure projects. Such as: foundation, basement, roads, and railway infrastructure and so on. 6, cisterns, tanks, cooling towers and other aggressive media and impermeability demanding projects. 7 recommended dosage: Marine Concrete with 10% -12% cementitious materials; other 8% -12% 8, implementation of standards: JC / T1011-2006, JTJ275-2000; product shelf life of one year.
