The method for measuring porosity of concrete is a vacuum pressure saturation-based method for calculating a porosity value of a sample of concrete. The method includes the steps of first drying a concrete sample and then making a first weight measurement of the concrete sample. Following the first weight measurement, the concrete sample is placed in a vacuum pressure vessel, where the sample ...

One of the most important factors in measuring effective porosity by vacuum saturation method is that the air in the pore space can be fully substituted by water during the vacuum saturation process. International Society of Rock Mechanics (ISRM) suggests vacuuming a rock sample submerged in the water, while American Society of Test and Materials (ASTM) vacuuming the sample and water ...

Total porosity measurement for gas shales without using crushed rock is presented. The method uses a modified saturation – immersion technique with deionized water. Porosity values are reproducible within a low average absolute uncertainty. Swelling in gas shales during saturation with deionized water is not significant.

Nov 10, 2020 . Porosity and fluid saturations are determined by a modified Dean-Stark extraction after initially bringing the samples to 100 per cent liquid saturation by a vacuum-pressure method. Horizontal permeabilities on the whole samples are determined in two directions, parallel and perpendicular to the direction of principal fracturing.
