A Novel System for In-situ Observations of Early Hydration Reactions in Wet Conditions in Conventional SEM

A novel system enabling wet microscopy in conventional SEM is described and its performance for in-situ study of hydration reactions is demonstrated. The technology is based on a sealed specimen capsule, protected from the microscope vacuum by an electron-transparent partition membrane. Thus, the wet sample can be placed and observed in a “conventional” SEM without the need for drying or employing environmental SEM. Early hydration reactions of gypsum and cement systems were followed during the first 24 h.
