The effect of calcium carbonate on the hydration procedure was also recorded. It is concluded that in pastes containing CaCO 3 , either as a chemical reagent or as a limestone constituent, the ettringite''s transformation to monosulfate is delayed, while calcium aluminate monocarbonate is preferably formed instead of monosulfate even at early ages.

C3A | Cement Science

According the investigation of Ingram et al., for a coination of 2% gypsum, 6% limestone, and 92% clinker, CaCO 3 reacts with C 3 A in the clinker. The reaction begins with a C 3 A·CaCO 3 ·12H 2 O product, then forms compounds containing a molar ratio of C 3 A to CaCO 3 between 0.5 and 0.25. Later, the product appears to stabilize as C 3 A
