Abstract:

Due to the strict requirements on the quality of the concrete for the lining of the passengerdedicated railway tunnels, it becomes a fundamental task of the testing center to produce durable concrete. In the paper, analysis is made on the mixing of the concrete for the lining of a tunnel on Shijiazhuang～Taiyuan passengerdedicated railway and conclusion is made that the indexes of the durable concrete can be controlled by controlling the watercementitious materials ratio.

Key words: passengerdedicated railway  , durability  , concrete water/cementitious materials ratio
