Influence of the test liquids nature on the unsaturated permeability of a basalt fabric

Résumé

The present work evaluates the influence of test liquids nature on the unsaturated and saturated permeability of a basalt fabric. To do this, four test liquids were chosen: water, polyethylene glycol, silicon oil and epoxy resin. The experimental approach consisted first of determining the viscosity and the surface tension, included the polar and dispersive components, of the test liquids and secondly, of characterizing the unsaturated and saturated permeability of the basalt fabric with the four liquids. The first results showed that the surface properties of the polyethylene glycol are the closest to those of epoxy resins, when compared to the other test liquids. However, its viscosity is ten times lower than the resin one. For the permeability experiments, the first results show a difference of 20% between results of water and PEG300. Other experiments with silicon oil and epoxy resin are currently carried out in order to complete these results and to investigate the influence of the test liquid nature on the unsaturated and saturated permeability.
