Calcium - Periodic Table of Elements: Los Alamos National …

Calcium from limestone is an important element in Portland cement. Solubility of the carbonate in water containing carbon dioxide is high, which causes the formation of caves with stalactites and stalagmites and is responsible for hardness in water. Other important compounds are the carbide, chloride, cyanamide, hypochlorite, nitrate, and sulfide.
