摘要
近年来,微膨胀水泥砂浆在我国建设中得到了大量应用,膨胀剂的加入,解决了水泥基材易开裂的缺点,促进了大量以微膨胀水泥砂浆为基材的各种灌浆料、墙体材料的出现,有些灌浆料甚至利用膨胀剂产生的自应力持力。在使用过程中,为改善微膨胀水泥的某一性能,通常需要改变配比或者添加其他材料,这又会对微膨胀水泥砂浆的其他性能产生影响,并且使用过程中的环境变量经常是不可控的。本文对常用的微膨胀水泥砂浆的性能影响参数进行了分析总结,对工程应用具有借鉴作用。
Light expansive cement mortar is widely used in recent years. Shrinkage is overcome by using expanding agent. Varieties of grouting and wall materials are emerged based on light expansive cement mortar,and the expansive force is even used to bear capacity. Many admixtures are added and mixture ratio is often changed according to different requirements,but all these will influence the other properties of light expansive mortar. The environment of both curing and usage period is often uncontrollable. Influence factors of light expansive mortar are discussed in this paper,and references can be offered for construction.
