基于短期试验预测混凝土长期收缩徐变

Long-period contraction creep forecast of concrete based on short-period test

介绍了常用混凝土收缩徐变预测模型,对预测混凝土长期性能的方法进行了探讨,指出利用混凝土短期收缩徐变试验数据进行回归拟合或对现有预测模型进行修正,可以达到准确而经济地预测混凝土长期性能的目的。

It introduces some forecast models of concrete contraction creep in normal service, discusses the methods forecasting long-period nature, points out it will reach the object of forecasting concrete long-period nature by the regression fit of short-period concrete contraction creep test data and the amendment to the forecast model exactly and economically.
