Abstract

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.

电渗透对接触金属壁的新鲜水泥浆基材料润滑的影响
本文研究了电渗透对水泥浆基材料与金属壁界面润滑效果的影响。本研究研制并建立了一种新的实验装置。试验采用了水泥浆基材料的两种尺度:水泥浆和砂浆。进行的试验如下:(i)电位差范围从5伏到30伏不等;(ii)金属板坡度范围为7°~ 15°。通过增大电位差和斜率,减少了预移动时间,提高了样品速度。测定了两种混合物的流变特性,以确定在润滑样品中起重要作用的界面流体膜的特性。在本研究中还确定了管理接触润滑的渗透系数。
