Abstract
The aim of this paper is to present a test procedure for the determination of gas (02, N2, air) permeability (m2) of a hollow cylinder porous material specimen. It applies in particular, but not exclusively, for measuring gas permeability of hardened concrete specimens. The gas permeability test in is carried out using a constant head permeameter. The design uses simple elements for easy measurements. This paper describes both the cell design and principles of operation of a novel aspect of experimental method and its application to the investigation of gas permeability of concrete. The form of concrete samples chosen reflects the present constructions cases where the permeability plays an important role in structures durability and security, such as nuclear power plants or storage structures. This laboratory method applies to molded cylinders samples and drilled cores of concrete. This device is able to measure the permeability values between 10-20 and 10-15 m2. The values obtained from this experimental procedure are similar to those found in literature.
