What is slag? - voestalpine

Dec 18, 2013  Slag is a byproduct of steel production and is similar in character to volcanic rocks such as basalt and granite. Slag is primarily used in the cement and construction industries, and largely in road construction. Slags are one of the most natural products of all. They are comparable to fluid magma from the earth’s core.
