摘　　要：目的研究现场发泡保温浆料受压性能及其对夹心墙受力影响.方法为考虑不同因素对现场发泡浆料受压性能的影响,针对砌筑所用砖型的选用及发泡浆料的厚度两个主要因素制作了6组试件,进行受压性能试验,并与用于填充夹心墙的EPS板和XPS板的抗压性能进行对比分析.结果由普通砌块制作试件的抗压能力高于由烧结多孔砖制作的试件,且抗压能力随发泡浆料的厚度的增加而明显下降,现场发泡保温浆料的抗压性能明显优于传统填板式夹心墙采用的EPS板、XPS板等填充材料.现场发泡保温浆料的抗压强度平均值为EPS板抗压强度平均值的2.65倍,为XPS板抗压强度平均值的1.39倍.结论现场发泡保温浆料具有良好的抗压性能,对协调现场发泡夹心墙内外叶墙体具有显著作用,但其抗压强度受厚度影响明显.The paper aims to research compression performance of foam-in-place thermal insulation mortar and its effect on mechanical performance of cavity wall. In order to consider impacts of different factors to the compression performance of foam-in-place thermal insulation mortar, the compression performance ex- periments on 6 groups of specimens were carried out. The group of specimens were divided by two major factors ：different kinds of masortry and different thickness Of foam-in-place thermal insulation mortar. Its compression performance is analyzed by comparison with XPS board and EPS board that fills cavity wall. The results show that compression capacity of specimens made with normal blocks is higher than that of specimens made with sintered porous brick; its compression capacity declined obviously when the thickness of thermal insulation layer increase. The compression capacity of foam-in-place thermal insulation mortar is obvious higher than that of EPS board and XPS board which were filled in Cavity Wall. The average compression strength of foam-in-place thermal insulation mortar is 2. 65 times higher than the EPS board and 1.39 times higher than the XPS board. Foam-in-place thermal insulation mortar has good compressive strength and plays an important part in coordinating the internal and external wall work together. However,the compression capacity of the foam-in-place thermal insulation mortar is influenced obviously with its thickness.
