ResumoAbstract Results of following the quantities of free Ca(OH) 2 and of tricalcium silicate (C 3 S) during the hydration of C 3 S, and also the influence of the presence of free CaO on this reaction are in accordance with the hypothesis of Stein & Stevels with regard to the hydration of C 3 S. at the first contact between C 3 S and water, a surface hydrate, invisible by electron microscope methods, is considered to be formed and to retard the reaction strongly. This hydrate is thought to change into one which retards the hydration reaction less and changes later into a third hydrate, tobermorite gel.
