Study of ettringite stability depending on external conditions

The doctoral thesis was focused on the study of thermodynamic stability of ettringite. Ettringite was first prepared in two different ways and then exposed in chosen environments. Furthermore, the stability of ettringite in interaction with calciumsilicates was investigated. As ettringite can be formed as a hydration product of fluidized bed fly ash, the properties of Portland fly ash cement in comparison with Portland cement and Portland slag cement were investigated at the end of the thesis
