The role of calcium carbonate in cement hydration

The diagram, Fig. 1, is constructed for lower temperatures, ∼ 25 °C, such that monosulfoaluminate tends to be persistent, although perhaps not actually stable [4].The impact of adding calcite on the paste mineralogy can be predicted as follows: select a horizontal line corresponding to the effective sulfur xide/alumina ratio, termed the …

Calcite Cement in Shallow Marine Sandstones: Growth …

Calcite cement in shallow marine sandstones normally cannot be derived from sources outside the sandstones owing to a lack of viable transport mechanisms for significant amounts of dissolved calcium carbonate. Within the sandstones the only significant source of calcite cement is usually biogenic carbonate, which is consequently considered to ...
