| 摘 要： | 本文针对欲将MgO膨胀剂应用于非水工大体积混凝土的设想,通过分析MgO膨胀剂的由来、质量及其控制、掺量及在水工大体积混凝土中的应用情况后指出,现有的水工外掺MgO混凝土的研究与应用成果,为高坝混凝土应用MgO膨胀剂奠定了坚实基础,但在非水工大体积混凝土结构中应用MgO膨胀剂时,应慎之又慎,切忌盲目套用。

| Abstract: | This paper intends to magnesium oxide expansive agent is applied to a non-hydraulic mass concrete, through the analysis of the origin of MgO expansive agent, and its control quality, content and application in the hydraulic mass concrete, points out that the existing of the additive MgO expansive agent of research and application of hydraulic concrete results and laid a solid foundation for high dam concrete application of MgO expansive agent, but in a non-hydraulic mass concrete structure, the application of MgO expansion agent should be cautious, avoid blindly applied. |

| Keywords: | magnesium oxide expansion agent MgO-mixed concrete origin application hydraulic mass concrete |
