Abstract
The gas penetration characteristics of concrete materials are important indicators that reflect their durability. The relationship between the slippage factor and intrinsic permeability is distinctly defined in theory and experiments for concrete materials. Oxygen permeability is tested by Cembureau method and concreate pore structure is gained by MIP measurement and SEM image. The pore tortuosity through a multi-diameter bundle capillary model was derived. As a result, a simplified equation between the slippage factor and intrinsic permeability was obtained through theory analysis and the relation is validated through gas penetration testing. And there is no direct correlation between pore size and slippage factor analyzed through provided equation. Aperture size gained by MIP method and slippage factor gained by Cembureau test method also shows no obvious regular relationship due to diversity of pore shapes.
