Description

This method, which is applicable to cast and cored concrete specimens, concerns the determination of the concrete permeability to oxygen conforming to the Hagen-Poiseuille relationship.
The apparatus consists of:

• Permeability cell for specimens 150 mm dia, 50 mm high
• Volumetric gas flow meter, soap bubble type
• High precision pressure regulator
• Digital readout unit and pressure transducer
• Stainless steel wall mounting panel and connections

Compressed oxygen cylinder fitted with pressure reducer (with outlet pressure from 5 to 10 bar (max outlet pressure not more than 5 bar) not included
