加荷龄期对徐变性能影响的一般规律在专著中已有论述:①加荷龄期小,相同持荷时间的徐变大,反之则小;②加荷龄期小,在开始一段持荷时间里徐变发展快,徐变速率衰减也快。加荷龄期大,在开始一段时间里徐变速率小,但徐变速率随持荷时间的衰减也慢;③当加荷龄期够大时,徐变度曲线实际上与龄期无关,这时混凝土可以认为已充分老化。加荷期龄对不同标号混凝土、不同和易性的常用标号混凝土徐变性能绝对值的
The general law of the effect of aging on the creep properties of aging has been discussed in the monograph: 1 The age of ageing is small, and the same holding time is larger, but vice versa; 2 The age of aging is small, and the beginning of the period is small. The creep of the charge time develops rapidly, and the creep rate decays quickly. The aging period is large, and the creep rate is small at the beginning, but the decay rate is also slow with the holding time; 3 When the aging period is large enough, the creep curve is virtually independent of the age. At this time, the concrete can be considered to be fully aged. Addition age of concrete for different labels, different workability common marking concrete creep properties absolute value
