Similar to limestone, dolomite additions can accelerate the hydration process, especially at early ages. This is ascribed to the fact that dolomite powder provides more nucleation sites and a high effective w/c ratio. 2. The reaction of dolomite in CSA cement is suppressed with increasing amounts of gypsum.
