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 S042-, Mg 2

β¦ Synopsis
The present work extends the knowledge on the behaviour of high magnesia cements, pure or with pozzolanic additives cured for 8 years in potable water at 18+2Β°C. For this purpose, clinker containing 10% MgO was prepared in an-appropriate furnace. The raw materials used were all of industrial origin.
Four cements were prepared by cogrinding clinker with gypsum and the following pozzolanic materials: Santorin Earth (S.E.), Fly Ash I (F.A.I.), Fly Ash II (F.A.II) and Fly Ash III (F.A.III), in a proportion of 30%.

The photoacoustic signal strength was measured on a series of similar portland cement pastes dried to different water contents. Under appropriate conditions this signal is a function of only the paste's specific heat capacity and thermal conductivity. Because of this, inferences can be made about th
