Ladle Furnace Slag Properties When Blended with Dolomitic Underutilized Quarry Materials

Dolomite, a mineral commonly found in Illinois quarries, may be used to improve the durability and stability of road foundations when stabilized with other materials. This project explores the use of ladle furnace slag, a material formed when making steel, as a way to reduce cement content in dolomitic materials while maintaining performance. Researchers aim to optimize the ratio of cement content, ladle furnace slag and fine-grained dolomite to create more durable road foundations. Effectively determining the ratio will help to reduce the cost of cement within dolomitic materials as well as open a market for underutilized quarry materials.
