True or False: Concrete can be made by mixing powdered

To make concrete, first you need to make the cement (or mortar) that holds the concrete together. The Romans did this by burning limestone (which is mostly calcium carbonate CaCO 3) to create something called quick lime (calcium oxide CaO). Burning isn't quite the right term because "to burn" usually indicates an oxidation process which
