2 days ago · Those containing only calcium carbonate (CaCO 3), calcium hydroxide [Ca(OH) 2], or calcium oxide (CaO) are called "calcitic limes." Pure calcium carbonate is used as the standard for materials and is assigned a rating of 100 percent. This rating is also known as the "calcium carbonate equivalent" and is referred to as the CCE.
