Anti-corrosion And Waterproof Of Bridge Body of Qingma Bridge
Tsing Ma Bridge is one of the top ten core projects built in coordination with the Hong Kong International Airport (Chek Lap Kok Airport). Construction of the Tsing Ma Bridge began in May 1992, and it was opened to traffic in 1997, which took five years to complete. The piers of the whole bridge all use CPC silane nano-waterproofing agent, which is 18 tons, and the effect is remarkable. CPC waterproofing agent is used on the bridge deck.
After detailed field and material laboratory tests, the contractor decided to adopt CPC silane nano-product technology to improve the waterproof performance of the bridge. This is not only because of the convenience of construction, but also because silane nanotechnology can achieve the best penetration depth and waterproof effect compared with ordinary waterproof materials. The dosage of CPC waterproofing agent is 100g/m2, the average penetration depth of active components can reach 3-5mm, and the absorption of water is reduced by more than ninety-seven percent.
