摘要
针对掺MgO膨胀剂混凝土的耐久性问题进行探讨,对比分析相关学者关于掺MgO膨胀剂混凝土的耐久性研究结论,指出影响掺MgO膨胀剂混凝土耐久性的两个关键问题和现状,经分析得出:MgO掺入混凝土后有利于混凝土更耐久;MgO用于大坝混凝土,可省去或部分省去传统温控措施,具有明显的经济技术效益,而且长龄期试验结果显示MgO混凝土用于工业与民用建筑也是可行的。
The thesis explores the durability of MgO concrete expansion admixture, comparatively analyzes relevant scholar5 s research conclu-sions about the durability of MgO concrete expansion admixture, and points out two critical problems and status of MgO concrete expansion admix-ture, and concludes that： MgO concrete expansion admixture will be good for concrete durability; MgO can save and partially save traditional temperature control measures when it is used in the dam concrete, which has obvious economic technical efficiency; Furthermore, long-age exper- imental results show that： MgO concrete is feasible in industrial and civil building.
