Calcium sulfo-silicate sulfo-aluminate cement and preparation method thereof

摘要: The invention discloses calcium sulfo-silicate sulfo-aluminate cement and a preparation method thereof. A main mineral phase of clinker the comprises following ingredients in parts by mass: 5-40 C4(AxF1-x)3$, 20-65 C5S2$, 5-15 C$ 5-20 C3A. steps calcining crude materials once at temperature 1,050 DEG C to 1,200 C, carrying out heat preservation for 1 hour or less, thereby preparing cement. According thereof, energy consumption CO2 discharge are lowered large extent, calcined has good grindability. presents early mechanical properties, sulfoaluminate minerals basically hydrated completely seventh day, already start hydrate so that problem later strength is solved; dihydrate gypsum generated from hydration can be converted into mono-sulfur tri-sulfur hydrate.
