  1. We determine the bulk density and porosity of monolithic materials using the Archimedes method, specifically Method 1 of DIN EN 623-2 and Method A of ASTM D792. This method is suitable for apparent porosity measurements greater than 1% and is essentially the same as ISO 1183.

  2. 1 sie 2019 · After a preliminary optimization step, three methods were used for quantifying porosity rate: the Archimedes method, the helium pycnometry and micrographic observations. The Archimedes method shows that results depend on the nature and temperature of the fluid, but also on the sample volume and its surface roughness.

  3. 1 lut 2016 · Therefore, the accurate measurement of porosity of the porous material is undoubtedly the first step to solid oxide fuel cell optimization. Seven batches of SYT samples with different porosity are investigated through image analysis method and Archimedeans porosimetry.

  4. 1 lip 2022 · The Archimedes method involves the use of an analytical balance and a density kit that together enable the measurement of the mass of the solid of interest in air and when submersed in a fluid, typically water or acetone.

  6. 18 maj 2024 · After conducting a thorough comparison of experimental approaches, the Archimedes method in demineralized water was found to be a more reliable method for determining the porosity rate in LPBF AM components.

  7. In construction materials the porosity is commonly measured by the Archimedes buoyancy method, from which the bulk density of the test specimen is also obtained. The porosity and the bulk density together fix the solid density of the specimen, as only two of the three quantities are independent.
