客运专线某标段耐久性衬砌混凝土的配制

Mixing of Durable Concrete for Lining of Passenger-dedicated Railway Tunnels

客运专线对混凝土有了更高的品质要求,配制耐久性混凝土已经成为试验工作的一个重点。对石太客运专线某标段的衬砌混凝土配制进行了分析,得出了通过控制水胶比可以控制混凝土各项耐久性指标的结论。

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.
