By definition, limestone is a marine sedimentary rock that contains at least 50 percent calcite. As the raw material for the manufacture of lime and cement, limestone is used by industry in enormous quantities. Lime (also known as quicklime, burnt lime, or caustic lime) is calcium oxide (CaO) and is produced by calcining finely ground limestone.

Crushed limestone is often the main raw ingredient in the manufacture of portland cement clinker that eventually becomes cement. Other raw material sources of calcium carbonate include shells, chalk or marl, which are combined with shale, clay, slate, blast furnace slag, silica sand or iron ore.

To make Portland cement—the most common type of cement—powdered limestone is heated in a rotary kiln. As a source of calcium, it joins with powdered clay to produce a product called clinker, which is then ground with a source of sulfate, like gypsum. It is mixed with water, sand and crushed rock to create concrete.

The Kalaka calcitic limestone is a massive secondary calcareous deposit mainly composed of calcrete and a small percentage of aragonite, both of which are forms of calcium carbonate (CaCO3). This deposit overlies the Silverton Group and some Bushveld rocks. The deposit attests to the presence of a paleo lake as the calcrete contains many ...

Calcitic limestone is a type of pulverized limestone often applied to overly acidic lawns to raise soil pH and restore nutrient availability. Normal lawn care naturally lowers soil pH over time, but applying lime unnecessarily can harm grass instead of help.
