Fig. 2From: Bohemian sandstone for restoration of cultural heritage sites: 3D microstructure and mass transport propertiesDistribution of pore radii derived from mercury intrusion porosimetry assuming an advancing contact angle of 130°. The left chart uses the common quantity on its ordinate, while the right one shows the distribution with the transformed ordinate, ρb dVHg/drp = (ρb/ln(10)/rp) dVHg/d log(rp), to stress the existence of narrower poresBack to article page
