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 ...

The Advantages of Portland-Limestone Cement| Concrete

Aug 12, 2014 · Portland-limestone cement has a smaller carbon footprint with no drawbacks. The concrete industry has been getting beat up for the past decade over the large carbon footprint of cement, and it’s true that cement manufacturing releases a significant amount of carbon dioxide into the environment. So if cement manufacturers come up with a way to improve concrete sustainability with no negative impacts on constructibility, performance, or durability, why would we resist using it?
