摘要
介绍了一种新型复合镁质膨胀剂,这种膨胀剂综合了钙矾石和氧化镁类膨胀剂的膨胀特点,即在水化早期钙矾石能提供膨胀作用,而后期氧化镁也能产生一定的膨胀量从而补偿混凝土的收缩,是一种优良的复合膨胀剂。
An expansive admixture is introduced in this paper.Ettringite expands at early age,otherwise,the Magnesium oxide based expensive admixture works later.Based on these two,a new expensive admixture was studied,and the two different mechanisms were combined together.
