Basic component of masonry mortar is : cement : sand : redispersion emulsoid powder: MC: AEA=1:2.5:0.015:0.002:0.08. Because the two special mortar is a single system, they are mixed with water to be used.

Influences of basic component (fiber, redispersable emulsoid powder, water-retentive admixture, expansive admixture, mixture and cement-to-sand ratio )of Dry-mixed Mortar on essential performance of mortar have firstly been summarized. The results show that :(1) After fiber is mixed into Dry-mixed Mortar , toughness ,crack resistance and unpermeability of mortar will be improved; Influence of different length mixed fiber on toughness of mortar precedes single-length fiber, but influence on crack resistance of mortar is the same.

该文首先研究了干拌砂浆的基本组分：纤维、可再分散乳胶粉、保水剂、膨胀剂、掺合料以及灰砂比对砂浆的基本性能的影响，结果表明：(1)在干拌砂浆中加入短切纤维，可以使砂浆的韧性得到改善，提高砂浆的抗裂性、抗渗性；不同长度的纤维进行混杂后对砂浆韧性的提高比单一长度纤维具有更好的效果，但对砂浆抗渗性的改善效果与单一长度纤维差别不大。

In the redispersable powders, WACER powder is excellent. When fine percentage of redispersable emulsoid powder is 1, toughness, adhesive performance of mortar have improved.(3) When MC was mixed into mortar, water-retentive performance, toughness, adhesive performance of mortar have improved and 28d dry shrinkage of mortar has reduced.(4) When AEA was mixed into mortar, dry shrinkage of mortar reduced and infiltration resistance has improved.(5) When cement-to-sand ratio is 1:2.5 , toughness of mortar is perfect.

2WACKER的VAE和551Z两种乳胶粉的效果较好，最佳质量掺量均为1%，对砂浆的和易性、韧性、粘结性能均有较大改善；(3)在干拌砂浆中加入MC保水剂后，砂浆的保水性提高，韧性得到改善，粘结性能也得到了增强，砂浆的28d干缩值也有所下降；(4)砂浆中加入AEA膨胀剂后，砂浆的干缩下降，抗渗性也有一定提高；(5)灰砂比为1：2.5是较为理想的，砂浆的和易性较好，韧性较好；(6)砂浆中加入掺合料可以使砂浆的韧性得到提高，但是会使砂浆的粘结性能下降。
