摘要
主要介绍低热微膨胀水泥掺氧化镁混凝土在洛古水电站导流洞封堵工程中的实践运用及效果,进一步证实了双膨胀混凝土的早期和后期膨胀及力学性能在水工封堵工程所起作用。
The paper mainly introduces the application of low - heat micro expanding cement blending oxidizing magnesium concrete to the diversion tunnel plug of Luogu Hydropower Project and its effect. The effects of expansion and mechanical property of early and post double expansion concrete are confirmed in the hydraulic structure plug work.
