中文摘要：

在简析Hansen和Pedersen基于Arrhenius原理建立的用于评价混凝土物性的温度依存性的等效龄期公式的缺陷和不足的基础上，考虑水化反应特征活化能的龄期和温度相关性，对文献中的试验数据加以回归分析获得特征活化能的龄期、温度函数，进而构建等效龄期修正公式。以等效龄期修正公式评价i种不同养护温度下高性能混凝土的白收缩特性，结果发现经修正公式变换后，各养护温度下的自收缩应变一等效龄期曲线的吻合程度较修正前更好。

英文摘要：

Defects and shortcomings of Hansen and Pedersen＇s equivalent age equation based on Arrhenius＇s principle for estimating temperature-age dependence of concrete properties are shortly discussed.In order to improve accuracy of estimation, a modified equivalent age equation is proposed.The equation includes a regression function considering age and temperature correlation of apparent activation energy of hydration reaction.Furthermore, the validity of the modified equation is testified by a series of experiment data on autogenous shrinkage of high performance concrete under 3 different curing temperatures.The result showed that shrinkage-equivalent age curves transformed by the modified equation coincide with each other well.
