摘　　要：自流平砂浆越来越广泛地应用于工程领域中,所研究的新型自流平砂浆是用来修复道路路面出现的坑洞。按照设计要求确定新型自流平砂浆的基础配合比,然后设置对比组来探究泵送剂和膨胀剂对新型自流平砂浆性能的影响,包括流动度、保水性、强度和尺寸变化等方面。试验研究得出不同掺量的添加剂对砂浆的性能产生不同的影响。Self-leveling mortar is more and more widely used in engineering field.The new self-leveling mortar studying was used to repairing the road pavement appeared craters.According to the design requirement, it determined mortar based mix proportion of the new self-leveling, then set contrast group to explore pumping agent and expansion agent on the performance of new self-leveling mortar effects, including flow degree, water retention, strength and size changes, etc.It got different effects at the different dosage of additives on the performanee of mortar.
