Kelley, Southard and Anderson 1 have shown that the thermodynamic properties of calcium sulphate hemihydrate depend on whether the hemihydrate is produced from gypsum calcined in a steam-saturated ...

The differential equation, the solution of which forms my complete equation for the hydration of calcium sulphate hemihydrate, was derived from one developed earlier to account for the self ...
