Carbonation of ternary cement systemsScienceDirect
Feb 01 2012 · Abstract The main hydration reaction product in the ternary system fly ash calcium sulphate and calcium aluminate cement (40/20/40) at 20 °C is a hydrated calcium sulfoaluminate compound an AFt phase slightly different from "traditional ettringite". The carbonation of ettringite develops gypsum but in this case rapidcreekite is formed.
