heal.abstract	This investigation concerns the effect of some ions, contained in seawater, on the hydration of cements containing 7% MgO, pure or with 30% pozzolan (Santorin Earth). Pastes prepared from these two cements were cured in five baths containing seawater, deionized water and aq. solutions of SO42-, Mg2+ and Cl- ions respectively for one year. The Mg(OH)2 produced during the hydration of the above cements was determined by DTA-TG, while the hydration phenomena were studied by XRD. It is concluded that the presence of Cl- and SO42- ions does not affect MgO hydration. Mg2+ ions increase the Mg(OH)2 content, mostly by their penetration in the pastes. The beneficial effect of the interground pozzolan is also shown. © 1990.	en
