Abstract
In a companion paper, the theory behind a novel method for measuring permeability and bulk modulus is derived. The new method is termed ‘dynamic pressurization’ (DP). In this paper, an apparatus for the new method is described, and the test procedure is applied to cement pastes and concretes. The test involves rapidly applying a hydrostatic pressure to a saturated cylinder, then measuring the time-dependent deformation response of the material. The test is found to be repeatable, and the fitting function described in the companion paper is found to adequately fit the measured data. The measured permeability of the cement pastes compares well to measured values on identical materials using a different technique. The measured bulk moduli of the solid phase of the hardened cement pastes and concretes obtained in the DP test are in the range of expected values based on literature values for the Young’s moduli of clinker and hydration products.
