The role of calcium carbonate in cement hydration — The

Limestone, mainly consisting of calcite, is a permitted additive to Portland cements often up to a 5 wt.% limit. It is shown by experiment and calculation that much, if not all, of this calcite is reactive and affects the distribution of lime, alumina and sulfate and thereby alters the mineralogy of hydrated cement pastes.

Modification of recycled concrete aggregate by calcium

Sep 01, 2012 · Highlights Calcium carbonate biodeposition method contributed to decrease in water absorption of recycled concrete aggregate. Better efficiency was obtained for finer aggregate fraction and in the case of aggregate of lower quality. Efficiency of calcium chloride and whey as culture media was confirmed. Observations under SEM showed covering aggregate grains with calcium carbonate.
