中文摘要：

我国叶蜡石资源丰富但利用率低，将叶蜡石替代水泥进行建筑砂浆试验，共设计了23组试件，进行强度和导热系数试验。结果表明，叶蜡石替代水泥对砂浆的性能有不同程度的影响，当叶蜡石掺量较低时，砂浆的强度基本不降低，当叶蜡石掺量较高时，砂浆的强度有不同程度的下降，研究结果为叶蜡石在砂浆中的应用提供理论参考。

英文摘要：

Our country is rich in resources but in a low utilization rate of pyrophyllite. In order to study the application of the pyrophyllite in the aspect of building materials, it was used to replaee cement for experiment of building mortar, designed 23 groups, testing strength and thermal conductivity. It turns out the influence of performance in different degree when cement replaced by pyrophyllite. When the content is low, reduction of mortar strength is not obvious, and when the content is higher, the strength has a different degree of decline. These results provide theoretical reference for the application of pyrophyllite in mortar.
