In the model of dolomite seen here (Figure 7.36), the blue atoms are calcium, the red ones magnesium, and the small aqua atoms are oxygen. Carbonate (CO 3) 2-groups are shown as yellow triangles. Other carbonates have similar structures. They all contain divalent anion carbonate groups and divalent cations such as Ca 2 +, Mg 2 +, …

Among the divalent cations, calcium combined with the carbonate anion makes a solid of low solubility. Calcium is the fifth and carbon the 15th most abundant elements in the Earth's crust, and their presence in natural waters accounts for the formation of mineral CaCO 3 by inorganic and biogenic processes in many environments.

Self-healing concrete incorporates calcium carbonate-producing bacterial spores, along with appropriate nutrients, which lie dormant until cracks form. Their exposure to water and air triggers the ...
