Mercury intrusion porosimetry parameters for use in concrete penetrability qualification using the Katz-Thompson relationship
This research studies relationships between pore parameters obtained from mercury intrusion porosimetry (MIP) and experimental results to determine the potential for those parameters to quantify concrete penetrability using the Katz-Thompson relationship. Water permeability, electrical resistivity, and chloride ion penetrability were analyzed as these test methods serve as a proxy for penetrability. Recent developments in mercury intrusion porosimetry accommodate testing larger concrete specimens instead of paste or mortar. Consequently, this work directly compares calculated and measured permeability of nineteen concrete mixtures. By oven-drying the MIP specimens, the calculated permeability was increased due to microcracking; however, when using the same specimen conditioning procedure for MIP and water permeability testing, the resulting calculated and measured water permeability values were comparable.
