主要研究了两种膨胀剂(UEA膨胀剂和轻烧MgO)对砂浆的收缩率及力学性能的影响。结果表明:随着膨胀剂掺加量的增加,砂浆的收缩率和力学强度逐渐降低;在降低砂浆收缩率方面,轻烧MgO的使用效果不及UEA膨胀剂;两种膨胀剂一块使用时,更有利于降低砂浆试样的收缩率,且砂浆的力学强度值与单膨胀组分砂浆强度值相近。
主要研究瞭兩種膨脹劑(UEA膨脹劑和輕燒MgO)對砂漿的收縮率及力學性能的影響。結果錶明:隨著膨脹劑摻加量的增加,砂漿的收縮率和力學彊度逐漸降低;在降低砂漿收縮率方麵,輕燒MgO的使用效果不及UEA膨脹劑;兩種膨脹劑一塊使用時,更有利于降低砂漿試樣的收縮率,且砂漿的力學彊度值與單膨脹組分砂漿彊度值相近。

It mainly studied the influence of two kinds of expanding agents(UEA expanding agent and light-burned MgO)on the shrink-age and mechanical properties of mortar. The results showed that the shrinkage and mechanical properties of mortar gradually decreased with the increment of adding expanding agent;to reduce the shrinkage of the mortar,the effect of UEA expanding agent was better;when the two kinds of expanding agents were used together,it was beneficial to reduce the shrinkage of the mortar,and the mechanical proper-ties of mortar was similar to the mortar with one kind of expanding agent.
