试验证明部分水泥的安定性检测结果可能会随存放龄期的延长由不合格变为合格。存放环境中时间和湿度会影响该变化的速度。但并非所有安定性不合格水泥都会随存放期延长变合格，只有因低温f-CaO导致安定性初检不合格的水泥才具有这种“时效”特性。%The test shows that the testing results of cement stability probably change from qualified into unqualified because of prolonged storage time, and time and humidity will influence the change rate. But not all the cement with unqualified stability will turn qualified for prolonged storage, and only the cement with unqualified stability caused by low temperature f-CaO in the initial survey has"time"feature.
