Foundry Slag In Asphalt
Foundry Sand - Material Description ORIGIN Foundry sand is a high-quality silica sand that is used to form molds for ferrous (iron and steel) and nonferrous (copper, aluminum, brass, etc.) metal castings. The raw sand is normally of higher quality than typical bank run or natural sands used in construction. (1)

Slag from steel mills in ferrous smelting, on the other hand, is designed to minimize iron loss and so mainly contains oxides of calcium, silicon, magnesium, and aluminium. Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide.

Blast Furnace Slag - Material Description ORIGIN In the production of iron, iron ore, iron scrap, and fluxes (limestone and/or dolomite) are charged into a blast furnace along with coke for fuel. The coke is combusted to produce carbon monoxide, which reduces the iron ore to a molten iron product.
Steel slag is a byproduct of iron and steel production by the metallurgical industries. Annually, 21 million tons of steel slag (SS) is produced in the United States. Most of SS is landfilled, which represents a significant economic loss and a waste of valuable land space. Steel slag has great potential for the construction of highway
