Lime (material) Wikipedia

Lime is a calcium-containing inorganic mineral composed primarily of oxides, and hydroxide, usually calcium oxide and/ or calcium hydroxide.It is also the name for calcium oxide which occurs as a product of coal seam fires and in altered limestone xenoliths in volcanic ejecta. The word lime originates with its earliest use as building mortar and has the sense of sticking or adhering.

Differences between Hydrated lime and quicklime Sodimate

The main differences between hydrated lime and quicklime are their reactivity & their chemical composition. Hydrated lime and quicklime are both calcium compounds. In its hydrated state, calcium is called calcium hydroxide, and in its pure state it is called calcium oxide, or quicklime.. Calcium oxide has a heavy density (65lb/ft³) and is more reactive than hydrated lime.
