By definition steel is a combination of iron with a small amount of carbon. Thousands of products having various chemical composition forms and sies are made of iron and steel by casting forging and rolling processes. Iron and steel comprise about 95 percent of all the tonnage of metal produced annually in the United States and the world.

Details+Dec 01 2016nbsp018332Steel slag is produced by the conversion of raw iron into steel around 125 million tons of it per year. Much of that is dumped and only a small portion used in embankments.
Details+Steel slag aggregates are highly angular in shape and have rough surface texture. They have high bulk specific gravity and moderate water absorption less than 3 percent. Table 181 lists some typical physical properties of steel slag. Table 18
Details+Steel slag also reduces CO 2 emissions because it is calcined in the steel making process. It also saves valuable raw materials for another day and the CO 2 pt that would be emitted from the clinkering process. Another benefit to the cement manufacturer from using steel slag is iron oxide in steel slag needed in the chemistry of Portland cement.
