Abstract

A low water/cement ratio ( w/c =0.20) hydrated Portland cement paste was analyzed by grid‐indentation coupled with ex situ scanning electron microscope‐energy‐dispersive X‐ray spectra (SEM‐EDS) analysis at each indentation point. Because finite element and Monte‐Carlo simulations showed that the mic...
