Switzerland Opening ceremony of Gotthard Base Tunnel

摘要

After nearly 20 years of construction, the Gotthard Base Tunnel in Switzerland will be officially opened on 1 June. Construction chemical products from BASF helped make the construction of the world's longest rail tunnel possible. The 57 km Gotthard Base Tunnel was built with around 4 million t of concrete - roughly 40 times as much as was used in Burj Khalifa, the world's highest building. BASF supplied concrete admixtures, cement injections to stop water ingress, and fire-protection mortar for the tunnel construction project.
