| 摘 要： | 采用快速冻融的方法,对混凝土在水中进行50、100、150次冻融循环后,得到其不同循环次数下的抗压强度,分别考虑了含气量、粉煤灰掺量和水胶比3个影响混凝土抗冻性的主要因素,分析了冻融环境下的混凝土力学性能.这些结论为在冻融环境下的混凝土含气量、粉煤灰掺量和水胶比的选择提出了建议,也为受冻融循环影响的混凝土结构进一步的研究提供了参考.

| Abstract: | The compressive tests of concrete specimens suffering 50,100 and 150 cycles of freezing and thawing in water respectively are carried.Mechanical properties of concrete are analyzed in different air entraining agents,fly ash contents,water binder ratio and strength.The conclusions provide the testing and theoretic basis for the deeper study of the concrete construction in freezing-thawing circumstance,suggestions of selecting the air entraining agents,fly ash contents and water binder ratio for the concrete ... |
