When limestone is heated in a kiln to approximately 1000ºC, carbon dioxide is driven off to form quicklime which, is mixed with water to create the less aggressive slaked lime (or builders lime Ca(OH) 2). Slaked lime when wet and exposed to the atmosphere will absorb carbon dioxide to reform calcium carbonate which has a cementing action.
