Roman cement, a Common card

The card carries these facts from its Wikipedia article.

• The name is misleading, as it is nothing like any material used by the Romans, but was a "natural cement" made by burning septaria – nodules that are found in certain clay deposits, and that contain both clay minerals and calcium carbonate.
• The burnt nodules are ground to a fine powder.
• This product, made into a mortar with sand, sets in 5–15 minutes.
