This paper presents an experimental investigation of the effect of electro-osmosis on lubricating the interface between the cement paste-based material and metal wall. A new experimental apparatus was developed and set up in this study. Two scales of cement paste-based materials were used and tested: cement paste and mortar. Tests performed were as follows: (i) range of potential difference varies from 5 to 30 V; (ii) range of metallic plate slope varies from 7° to 15°. The pre-movement time was reduced and the sample velocity was increased by increasing the potential difference and the slope. The rheological properties of two mixtures were determined to identify the characteristics of the fluid film at the interface that plays an important role in lubricating the sample. The permeability coefficient for managing the contact lubrication was also determined in this study.

本文对电渗透对润滑水泥浆基材料和金属壁之间界面的影响进行了实验研究。本研究开发并建立了一种新的实验装置。使用并测试了两种等级的水泥浆基材料：水泥浆和砂浆。进行的测试如下： (i) 电位差范围为 5 至 30 V；(ii)金属板坡度范围从7°到15°不等。通过增加电位差和斜率来减少预移动时间并增加样品速度。确定两种混合物的流变特性，以确定界面处液膜的特征，该液膜在润滑样品中起着重要作用。
