What is Driveway Slag?
Driveway Slag is a co-product produced at the steelmill. It varies in size with the largest being about 1 1/4" in size. The smallest is granular and even sometimes powder like.
Slag is a partially vitreous by-product of smelting ore to separate the metal fraction from the unwanted fraction. It can usually be considered to be a mixture of metal oxides and silicon dioxide.
