To combine design requirement of segment of Wuhan Yangtze Tunnel, mix proportions of high performance concrete of segment were designed.Mechanical property,impermeability and microstructure of high performance concrete of segment were investigated.Because interfacial transition zone between aggregate and cement paste and pore structure was improved,the impermeability of high performance concrete of segment was increased.Thus, the main technical indexes of segment that was produced could meet design requirement of segment of Wuhan Yangtze Tunnel.
