摘　　要：本文介绍了补偿收缩混凝土应用于巫山长江大桥钢管混凝土中的情况,试验和工程应用结果表明,对于高性能自密实微膨胀混凝土,采用膨胀剂和化学外加剂双掺的效果比复合型膨胀剂施工性能要好。This article introduced that the situation of shrinkage-compensated applied in the Wushan Yangtze Bridge steel tube concrete. The results of the experiment and the project application indicated, for high performance and self-dense micro expansive concrete, the effect of expansion agent and chemical double-mix additives is better than the complex mode expansion agent in construction performance.
