Abstract

Abstract The water/cement ratio at which Portland cement is hydrated is shown to influence the early hydration behaviour. Results have been obtained with both an ordinary Portland cement and a white Portland cement. As the water/cement ratio was progressively raised from 0.3 through 0.4 to 0.5, increased quantities of ettringite were formed at all the hydration times studied up to two hours. The results have been interpreted on the basis of a through solution mechanism for the formation of ettringite.
