Description
A new method to measure threshold pore size of concrete was developed. Samples for MIP analysis were coated with epoxy-resin and the maximum slope of the obtained cumulative pore size distribution is defined as threshold pore radius. Threshold pore radius obtained with the new method showed good correlation with surface air permeability and water permeability. Gas permeation was plotted on two lines against threshold pore size and the point of intersection between the two lines agreed with theoretical transition zone of diffusion. The obtained results indicated that threshold pore size governs various mass transfer such as air permeability, water permeability, and gas permeation.
