Thermal Stability of Ettringite Exposed to Atmosphere: Implications for the Uptake of Harmful Ions by Cement

The decomposition behavior of ettringite, Ca6Al2(SO4)3(OH)12·26H2O, at different temperatures was studied by means of isothermal XRD experiments, in which the evolution of the solid is monitored as a function of time. The experiments were performed at 40, 50, 55, and 60 °C for a natural ettringite s...
