Concrete with GBFS and limestone. Both GBFS and limestone can be used in concrete either as main cement component or concrete addition. However, their contribution to the strength development and durability is very different. In an alkali environment, GBFS reacts with water and forms calcium silicate hydrates (CSH).

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).

Concrete, usually Portland cement concrete, is a composite material composed of fine and coarse aggregate bonded together with a fluid cement that hardens over time—most frequently in the past a limebased cement binder, such as lime putty, but sometimes with other hydraulic cements, such as a calcium aluminate cement or Portland cement.
