Pore analysis of porous construction materials by metal intrusion – extending the limits of Washburn’s equation

This study focuses on developing analytical methods associated with metal intrusion technique to address some of the limitations of Washburn’s equation, allowing more comprehensive pore analysis from the perspective of pore shape and the spatial distribution of pores. A study of metal intrusion at the nanoscale is also conducted to provide a foundation for future nanopore analysis by metal intrusion, which exceeds the detectable pore size limit of Washburn’s equation.
