Slag #73

#73 slag is a durable, graded aggregate typically sized between 1/2 inch and 1 inch. Produced from processed steel slag, this angular material offers excellent strength, stability, and drainage. Compared to finer base materials, #73 slag provides a more open structure while still locking together effectively under load, making it suitable for both structural and drainage-focused applications.

Its toughness and resistance to breakdown make it a reliable choice for demanding construction environments.

Common applications for #73 slag

• Concrete production and aggregate blends
• Road base and access road construction
• Structural fill and site preparation
• Drainage layers and trench backfill
