This paper showed the results of experimental study on the effects of different types and adding amount of alkali on the loss rate of water and the drying shrinkage of cement paste.

通过测量不同品种和掺量的碱对水泥基材料的水分损失量和自由收缩率，研究了在干燥条件下不同的碱对水泥基材料收缩性能的影响规律。

Moreover, the relation between the loss rate of water and the drying shrinkage of binder paste is tight and namely free shrinkage 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。
