| 摘 要： | 研究了氧化镁水泥混凝土的物理、力学、变形等性能．结果表明：在混凝土中掺入氧化镁使其自生体积膨胀，其膨胀具有延迟性的特点；混凝土的抗压强度随氧化镁掺量的增加而降低；混凝土的自生体积变形随氧化镁掺量的增加而增大；养护温度越高，自生体积变形越大；氧化镁掺量对混凝土的干缩变形及绝热温升没有明显影响．

| Abstract: | This paper researches into the properties of concrete containing magnesium oxide. The results show the volume expansion of concrete has time-lag characteristic. Compressive strength decreases as the increasing of magnesium oxide content. Volume expansion of concrete increases with magnesium oxide content. The higher the curing temperature the greater the volume expansion. Magnesium oxide content has no obvious effect on dry shrinkage and adiabatic temperature rise. |
