Transparent soil has been investigated for its potential as a substitute research media for natural soil. The mechanism for manufacturing the transparent soil is through adding an appropriate pore fluid to silica gel particles with the same refractive index. Two types of high viscosity pore fluids were identified by Iskander in 1994. However, because of the high viscosity of these two pore fluids, air was easily entrapped, which made the manufacture of a large mass of transparent soil difficult. In addition, the identified pore fluids caused serious membrane deterioration during triaxial laboratory testing. This research presented herein is an experimental investigation on low viscosity pore fluids to manufacture transparent soil, including the fluid/particle interaction in the stimulant matrix. Two low viscosity pore fluids were identified with minimum interaction with latex membranes.
