摘要
本文通过对单掺减水剂和减缩剂以及双掺减缩剂和减水剂砂浆干缩性能的研究,指出减缩剂和减水剂存在相容性问题,即某些种类减水剂和减缩剂双掺时砂浆的干缩值要大于单掺相应减水剂砂浆的干缩值。
Through study of drying shrinkage of mortar with addition of water reducing agent or shrinkagereducing agent alone as well as addition of both , consistency of shrinkagereducing agent and water reducing agent was found, that is, the drying shrinkage of mortar with double addition of some shrinkagereducing agent and water reducing agent higher than that of mortar with the same water reducing agent alone.
