因此，对特细砂混凝土塑性收缩防裂措施进行研究，具有重要的现实意义。
Thus, research on measures for superfine sand concrete to get rid of plastic shrinkage cracks is of important practical significance.
目前关于塑性收缩裂缝的研究几乎都集中在中粗砂混凝土，对于特细砂混凝土塑性收缩裂缝及其相关问题的研究几乎没有。
But almost all the attention of the plastic shrinkage crack are focus on the medium and coarse sand concrete and the study of super fine one not found.
