| 摘 要： | 研究了养护温度和水泥碱含量（质量分数，下同）与硅质集料砂浆试样膨胀的关系。温度对砂浆膨胀影响较大，采用８０℃碱溶液养护，试验更迅速，结果更敏感。水泥碱含量对砂浆膨胀的规律影响较小，但对膨胀值有明显影响。采用加碱方法调整水泥碱含量可以有效地控制试验条件，使试验更迅速、准确

| Abstract: | The influences of curing temperature and alkali contents of cement on expansion of mortar bars are investigated. The influence of temperature is greater; the testing is faster and the results is more sensitive at curing temperature 80. The influence of alkali contents of cement is smaller on expansion trend of mortar bars, but is bigger on the expansion values. The test condition is effectively controlled by modifying alkali content of cement with adding alkali; so, the testing is faster and more accurate. |
