Abstract

The paper proposes a semi-dynamic dual chamber method to measure the partition coefficient and diffusion coefficient. It is advantageous over the earlier dynamic dual chamber test method in that it works for both porous materials and those close to impermeable materials. Our toluene –cement mortar test demonstrated the feasibility of such method although further improvements can be done through more reliable measurement instrument and better sealing of the system.
