摘要
本文论述了观测时间长达10年及20年的外掺轻烧MgO和内含MgO水泥混凝土自生体积变形的试验研究成果,简要介绍了MgO水泥的膨胀机理。通过长达12年的力学与变形性能试验,阐明了MgO混凝土的长期力学性质是安定的。微膨胀对混凝土长期力学性能的影响不大。
Abstract In this paper is presented the research result of cement concrete containing MgO microexpansional agent over a long term of 12 to 20 years.The agent is mixed into the cement with different methods.The expansion mechanism of MgO is briefly introduced.The long term research result shows that the mechanicl behavior of MgO concrete is stable.The microexpansional agent has little effect on the long term mechanical properties of the concrete.
