An experimental apparatus and analytical derivation are developed for quantifying the permeability of cementitious materials using dynamic pressurization of a hollow cylinder. Experimental results from the newly developed hollow dynamic pressurization technique for measuring permeability are then compared to results obtained using the solid dynamic pressurization test. The measured permeabilities obtained from testing Vycor glass and hardened cement paste indicate close agreement between the two test methods, which supports the validation of the hollow dynamic pressurization test as an accurate and repeatable method for measuring the permeability of cementitious materials. Three different pore fluids with widely varying viscosities were tested, each yielding equivalent intrinsic permeabilities. Additionally, the permeability values from this study agree reasonably well with relevant values presented in the recent literature. 2008 Elsevier Ltd. All rights reserved.
