Nearly 84 percent of all boiler slag generated annually in the U.S. is utilized (ACAA 2007). More than 85% of the boiler slag is used as blasting grit and roofing shingle granules. Boiler slag is also used in transportation applications including structural fills, mineral filler, and snow and ice control (ACAA 2007).
Since boiler slag is angular, dense and hard, it is often used as a wear-resistant component in surface coatings of asphalt in road paving. Finer-sized boiler slag can be used as blasting grit and is commonly used for coating roofing shingles. Other uses include raw material for the manufacture of cement and in colder climates, it is spread
