Micro-structural characteristics of concrete were determined with the help of a helium gas pycnometer and a mercury intrusion porosimeter. Details of the methodology adopted for these studies are presented in this technical note. Results in the form of ratio of solids to the pore volume were plotted with respect to the compressive strength of concrete and suitability of Watson’s strength-porosity model for concrete was evaluated. In addition to this, based on the study attempts have been made to recommend the value of parameters for concrete that appear in Watson’s strength-porosity model, which otherwise is applicable to hydrated portland cement pastes only.
