Calcite [calcium carbonate, CaCO. 3] is a mineral that needs little introduction. It is the most abundant carbonate mineral and second only to quartz [silicon dioxide, SiO. 2] in overall crustal abundance. It crystallizes in the trigonal system (a hexagonal subsystem), has a Mohs hardness of 3.0, and specific gravity of 2.7-3.0. Calcite crystals occur in an exCalcite Cement in Shallow Marine Sandstones: Growth,,Biogenic carbonate is less stable than calcite cement, and once a calcite cement nucleus has formed it will lower the concentration of dissolved calcite within its range of influence. Biogenic carbonate will then dissolve around the growing nucleus, diffuse down the concentration gradient and precipitate on the surface of the growing nucleus or concretion. This process will continue until the available biogenicThe role of calcium carbonate in cement hydration,,01/04/2007· Calcite affects the mineralogical variant of the AFm phase(s). Calcite additions affect the amount of free calcium hydroxide as well as the balance between AFm and AFt phases, although C–S–H is unaffected in much of the range of compositions.

Each 100 mg/l of Calcite will neutralize 44 mg/l of carbon dioxide. So I cubic foot (about 100lbs) of Calcite will treat about 96,800,000 mg of carbon dioxide. If water has 20 mg/l of carbon dioxide then 1 cubic foot will treat: (96,800,000 / 20) liters of water. Or 4,840,000 liters or 1,278,730 gallons of water.
