| 摘 要： | 目前,工程界已开始重视地热对隧道施工和工程质量的影响,但总的来说还没有针对性强与很有效的技术措施。文章以在混凝土中掺入矿粉、掺入粉煤灰、同时掺入矿粉与粉煤灰为对照,在70℃条件下养护后,测定其力学性能,探究矿粉与粉煤灰对高温养护混凝土力学性能的影响,并寻求最优方案,为热害环境混凝土掺合料的使用提供依据。

| Abstract: | Recently,engineering field has paid more attention on the influence of geothermal on tunnel construction and construction quality.However,in general,there are little strong targeted and effective technical measures.Taking adding mineral powder,fly ash,mineral powder as well as fly ash to concrete for comparison,after the maintenance in 70 ℃ condition,this paper determines the mechanical properties,explores the influence of mineral powder and fly ash on the mechanical properties of high temperature maintenance concrete,and seeks the optimum scheme,which provides evidence for the use of concrete mixed material in hot environment. |
