NEW TECHNIQUE FOR THE STUDY OF CEMENT HYDRATION BY SCANNING ELECTRON MICROSCOPY

A new scanning electron microscopy technique is described which permits the study of cement hydration in greater detail than by other methods. Its chief advantages are (1) high sensitivity to early stages of hydration; (2) ability to detect amorphous as well as crystalline phases; and (3) ability to distinguish the behavior of individual components (cement or aggregate) of concrete during hydration. Examples of results obtained by this technique are presented.
