矿物细掺料对装饰砂浆性能的影响研究

Influenced Reseach of Fine Mineral Mixture on the Properties of Decoration Mortar

本文研究了不同掺量下石灰石粉和石英粉两种矿物细掺料对装饰砂浆吸水性、力学性能及泛碱性的影响。结果表明:掺15%的石英粉能有效降低装饰砂浆吸水量,提高其力学性能,并且抑制砂浆泛碱效果较好;而掺石灰石粉的装饰砂浆吸水量增加,强度有所下降,抑制砂浆泛碱的作用效果也不明显。

The influence of different dosage of limestone powder and quartz powder on hydroscopicity , mechanical properties, and whiskering of decoration mortar were investigated. The results show that quartz powder can effectively reduce water absorbing capacity of the decoration mortar and improve its mechanical properties. In addition we could restrain decoration mortar whiskering by combining fifteen percent of the quartz powder. But limestone powder increased the hydroscopicity and decreased the strength. Moreover, there was no obvious whiskering inhibitory effect on decoration mortar.
