对于压实试样,初始干密度和含水率对收缩特征有重要影响:初始干密度增加对体积收缩变形起抑制作用,而初始含水率的增加对体积收缩变形起促进作用。

The drying shrinkage strain develops slowly, since it is a function of the migration of the water through the hardened concrete.
干燥缩水应变发生较慢，因为它是一个水透过硬化混凝土的迁移作用。
Along with percentage of water loss and aggregate grade, the laws of small beam dry shrinkage strain and average dry shrinkage index.
小梁干缩应变、平均干缩系数随失水率、集料级配的变化规律。
Throughout the drying process, the surface of the free shrinkage strain is the largest, the more close to the core layer the smaller the free shrinkage strain.
在整个干燥过程中，表层的自由干缩应变最大，越靠近芯层自由干缩应变越小。
