| 摘 要： | 本文研究了外掺MgO混凝土的膨胀及其在约束条件下的强度。试验结果表明,MgO混凝土的膨胀随MgO膨胀剂掺量的增加而增大,养护温度越高,膨胀速度越快。在MgO膨胀剂掺量与养护温度相同的条件下,二维约束能够提高外掺MgO混凝土的强度。

| Abstract: | The expansion and strength of concrete with MgO-type expansive agent were studied in this paper.Results showed that with increase of amount of MgO-type expansive agent,the expansion of concrete increased correspondingly.Furthermore,raising the curing temperature could enlarge the expansion rate of the concrete.The strength of concrete can be raised by two-direction restrain under the same conditions such as MgO content and curing temperature. |
