Farm structures - Ch3 Building materials: Burnt-clay …
Non-hydraulic lime is high-calcium limes that are produced by burning fairly pure limestone, essentially calcium carbonate, so as to drive off the carbon dioxide leaving calcium oxide or quicklime. The burning process requires a temperature of 900 to 1 100° C. Quicklime must be handled with great care because it reacts with moisture on the skin and the heat produced may cause burns.

Is Calcium Citrate Better Than Calcium Carbonate? | …
Calcium content: Calcium carbonate is the most prevalent calcium supplement in the market. It provides more elemental calcium than calcium citrate, so you may not need to take as many pills. As in the example explained in the elemental calcium section, a 500 mg calcium carbonate provides 200 mg elemental calcium.
