Abstract	Systematic sequential observations with the electron microscope were made of the morphological changes which occurred during hydration of C(3)S and C(2)S pastes, with and without the presence of gypsum. The specific effects of each of two admixtures were studied: triethanolamine and calcium lignosulphonate. Water to C(3)S or C(2)S ratio was 0.5 and admixture dosage was 0.5%. The admixtures had some effect on changes in microstructure, but they had a pronounced influence on the rate of the hydration processes.
