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。
The mechanism of cracking is the different rates of water loss in different depths which caused the uneven shrinkage deformation.
揭示了裂隙产生的机理是不同埋深处土体水分丧失速率的不同，产生了不均匀的收缩变形。
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。
The results indicate that with the increase dosage of fly-ash, the loss of water and drying shrinkage of cement paste increase.
结果表明：随粉煤灰掺量的增加，净浆失水率及干缩率随之增大。
The capillary pressure which is the effect of the water loss from the concrete surface, is the origin of the plastic shrinkage in concrete cracking.
由于这种裂缝是由于混凝土塑性收缩引起，所以称之为塑性收缩裂缝。
