AbstractSystematic sequential observations with the electron microscope were made of morphological changes which occurred during hydration of a paste mixture of C[3]S, C[2]S, C[3]A, C[4]AF and gypsum. The pronounced effect on rate of hydration of each of two organic admixtures was clearly observed. Differences could be seen also in the stability and habit of hydration products and in the microstructure itself. The electron micrographs shown illustrate the forms of the products at different hydration times.
