| 摘 要： | 对外掺MgO混凝土在不同恒温和变温场中的基本物理力学及变形性能进行了全面和系统的试验研究,揭示了温度对MgO混凝土力学性能的影响程度,并提出了与温度和龄期相关的经验公式。通过计算得出,混凝土的力学指标在恒温和变温场中的试验结果相差甚小,在仿真分析中,用恒温成果替代变温结果是可行的。

| Abstract: | In this paper, the characteristics of concrete with MgO, including properties of basic physics mechanics and deformation in different constant temperature fields and inconstant temperature fields have been tested and studied fully and systematcally. The tests revealed the effects of temperature on mechanics properties of concrete mixed with MgO. This paper puts forward some empirical formula that relates to temperature and ages. On the basis of calculation, the discrepancy of mechanics indexes of concrete in constant temperature field and inconstant temperature field is unconspicuous. In simulation analysis, it is feasible to instead constant temperature result of inconstant temperature data. |
