The drying shrinkagestrain 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 shrinkagestrain 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 shrinkagestrain is the largest, the more close to the core layer the smaller the free shrinkagestrain.
