Chat Online· 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.
