A high pressure permeameter for the measurement of liquid conductivity of porous construction materials

Equipment is described which provides measurements of the pressure and volume of unidirectional liquid flow through sample cores of porous solids. The real-time measurement of flow pressures enables any changes in conductivity resulting either from interactions with the flow liquid or from changes in effective stress levels to be monitored directly. The equipment can use a range of flow liquids and be adapted for miscible and immiscible displacement studies. It is particularly suitable for cement-based and stone construction materials.
