| 中文摘要: |
| 本文提出计算微膨胀混凝土自生体积变形的室内试验结果与现场实际值差别的方法并建立了考虑这一差别的自生体积变形计算模型，指出了后 期膨胀的重要影响。最后提出了氧化镁混凝土的高温快速试验方法。 |
| 英文摘要: |
| The method for calculating the bulk expansion difference between experimental result and in prototype of gentle expansive concrete is analyzed. A formula for calculating the increments of self-expansive volume strain at different ages in consideration of this difference is derived. it is pointed out that the influence of later age expansion is significant. The improved experimental method for gentle expansive concrete is proposed. |
