The solidification shrinkage mechanism of unsaturated polyester resin is analysized by using free Volume theory in this paper.
本文用自由体积理论分析了不饱和聚酯树脂的固化收缩机理。

Moreover, the relation between the loss rate of water and the drying shrinkage of binder paste is tight and namely freeshrinkage was increased with the increase of loss rate of weight.
同时，发现碱作用下水泥基材料的水分损失与收缩过程密切相关，即浆体的收缩随着水分的损失更加明显。

Throughout the drying process, the surface of the freeshrinkage strain is the largest, the more close to the core layer the smaller the freeshrinkage strain.
