Comparaison de différentes méthodes de mesure du degré d'hydratation de pâtes de ciment Portland durcies
This study, achieved as a part of the research project “Transfers in concrete and durability of structures”, deals with comparative measurements between two methods which evaluate the degree of hydration of different hardened Portland cement pastes: classical measurement of the chemically bound water, and image analysis on polished sections by scanning electron microscope in backscattered mode (SEM—BSE). The water/cement ratio ranging from 0.25 to 0.6 and time from 28 days to 2 years, are the two majors parameters of this study. The results indicate a good agreement between the two methods. Assumptions, advantages and limitation of each method are discussed, especially, when applied to other types of cements and to concrete.
