Steel Slag BOF slag, commonly known as steel slag is another waste from iron & steel industry. It has shown potential for use as a raw mix component up to 10% in the manufacture of cement clinker. Steel slag can also replace granulated blast furnace slag up to 10% in the manufacture of Portland Slag Cement. Steel slags are produced at steel melting

2. Overview of Iron/steel Slag 2.1 Iron/steel slag production Slag is produced during iron and steelmaking processes, origi-nating from the gangue in the mineral raw materials such as iron ore, coal, and limestone as well as those in the flux used at steel re-fining processes to remove Si, P, S, and other impurities in molten
Cement is so fine that 1 pound of cement contains 150 billion grains. The cement is now ready for transport to ready-mix concrete companies to be used in a variety of construction projects. Although the dry process is the most modern and popular way to manufacture cement, some kilns in the United States use a wet process.

There are several different types of steel slag produced during the steel-making process. These different types are referred to as furnace or tap slag, raker slag, synthetic or ladle slags, and pit or cleanout slag. Figure 18-1 presents a diagram of the general flow and production of different slags in a modern steel plant.
The most important method of regulation used with the low-percentage Al2O3 slag cements in the U.S.A. is the Whiting process. This process includes the use of caustic soda, caustic potash, sodium chloride, &c., added either as aqueous solution or in a dry state at some stage of the process of cement manufacture.
