| 摘 要： | ＭｇＯ型水泥膨胀机理，混凝土变形规律必须满足温控设计要求，ＭｇＯ微膨胀混凝土的补偿作用要以混凝土坝温度应力理论给予解释。ＭｇＯ型水泥或膨胀剂有较好的延迟膨胀性能，而且长期稳定。外掺ＭｇＯ微膨胀混凝土筑坝技术在广东省青溪水电站和福建省水口水电站大坝上的应用是成功的。

| Abstract: | The compensation effect of the MgO weakly expanding concrete must meet the requirements of the design for temperature control,which is based on the temperature stress theory of concrete dams.The MgO expanding cement is possessed of the better quality of delayed expansion and long period stability.The technique of dam construction with MgO weakly expanding concrete has been used successfully in the construction of the Qingxihydro plant in Guangdong Province and the Shuikou hydropower saution in Fujian Province. |
