Investigation of the CaO–Al2O3–SiO2–CaSO4–CaCO3–H2O system at 25oC by thermodynamic calculation
Source abstract
Abstract
The phase diagram of the CaO–Al2O3–SiO2–CaSO4–CaCO3–H2O system relevant to cement has been calculated at 25°C and 1 bar pressure. It is composed of 331 stable phase assemblages in equilibrium with the aqueous phase and contains 30 invariant points with 15 solids. Thaumasite appears to be a stable phase with a wide stability domain. Compared to ettringite, thaumasite is stable to lower pH and generally demands higher sulphate concentrations to be stable.
