Appropriate simulation of air flow in porous media needs an accurate estimate of relative air permeability (RAP). Combining 2 traditional and 2 fractal water retention curves (WRCs) respectively with 6 permeability equations, we obtained 12 statistical ...

Air permeability of needle-punched filter media—virgin and recycled polyester
Journal of the Textile Institute, 2020Air permeability is an important property of any filter media and mostly depends on its constructional parameters. In this article, virgin and recycled polyester fibers were used to prepare needle-punched nonwoven filter medium varying fabric weight (GSM

Effects of self-healing on tensile behavior and air permeability of high strain hardening UHPC
Construction and Building Materials, 2019High strain hardening UHPC was expected to be self-healing due to its multiple micro-cracks in tension and the low water-to-binder ratio. The direct tensile tests with the acoustic emission (AE) analysis method and air permeability tests were carried out

Influence of structure and stretch on air permeability of compression knits
, 2020Air permeability has a valuable role in comfort parameters. It is known that air permeability of elastomeric yarns is firmly low. Despite that, usage of elastomeric inlay-yarns is the most common and the most effective way to generate compression for ...

AbstractAir permeability was determined for concretes of variable porosity (w/c ratio of 0.33, 0.50, and 0.67). The reproducibility of the test and the ability to characterize the permeability of different concrete were evaluated. Results indicate that air permeability test gives suitable reproducibility with a margin of error of 10%, which tends to ...
