Portland cement is the main component of concrete and it is made using a highly evolved recipe of calcium, silicon, aluminum, iron, gypsum and other ingredients. Modern portland cement is manufactured using giant rock crushers and industrial kilns. But the Romans, who built the Coliseum out of concrete, used much simpler technology.
The more advanced way to smelt iron is in a blast furnace. A blast furnace is charged with iron ore, charcoal or coke (coke is charcoal made from coal) and limestone (CaCO 3 ). Huge quantities of air blast in at the bottom of the furnace, and the calcium in the limestone combines with the silicates to form slag.
Blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux (either limestone or dolomite) are melted together in a blast furnace.When the metallurgical smelting process is complete, the lime in the flux has been chemically combined with the aluminates and silicates of the ore and coke ash to form a non-metallic product called blast furnace slag.
The iron melts in the hot temperature and is tapped off in liquid phase at the bottom. It is then worked into steel. The limestone and bedrock form a compound called slag. It can be used for making bricks, concrete or road topping. Aluminum is smelted in electric ovens called electric arc furnaces. The aluminum ore is poured on the bottom of ...
Abstract. This paper aims to investigate the possibility of utilizing steel slags produced in Croatian plants as a concrete aggregate. Aggregate properties were determined on coarse slag fractions (4–8, 8–16 mm) according to the relevant European Standards.
