Abstract: The mixing proportion of the concrete for the large diameter and high performance segments of Qianjiang tunnel in Hangzhou is studied. The optimal mixing proportion is obtained by testing on the raw materials produced in Hangzhou. Permeability tests and diffusion tests are made, so as to ensure the durability. The concrete has been successfully used in Qianjiang tunnel. The paper can provide guidance for similar projects in the future.
