Slag

#2 Slag: graded 1.5 to 2.5 inches in diameter. It is characterized by its coarser texture, making it an ideal choice for applications such as road base, fill material, drainage aggregate or even giving that decorative "moon" vibe.

#53 Slag: 1.5 inch fines. This size range makes it particularly versatile, commonly employed in concrete production, road construction, and landscaping projects.

#73 Slag: graded to pass through a sieve with apertures of 1 inch in diameter and retained on a sieve with apertures of 0.5 inches. With a coarser texture compared to #53 slag, it finds similar applications in concrete production, road base construction, and fill materials.

#8 Slag: has undergone grading to pass through a sieve with apertures measuring 3/4 of an inch in diameter. This size renders it finer compared to #2 slag, making it suitable for various applications including concrete mixes, asphalt mixes, or as a drainage material.

INDOT #2 Slag is a coarse aggregate with stone sizes typically ranging from 2–3 inches. This durable material is ideal for heavy-duty base layers, stabilization, and erosion control in large construction projects.

Best Uses: Road base, construction entrances, stabilization, erosion control.

INDOT #5 Slag consists of crushed steel slag ranging from 1 inch down to dust. Its angular shape provides excellent compaction, making it a dependable choice for road base, driveways, and commercial foundations.

Best Uses: Driveways, road base, structural fill, heavy-duty pads.

INDOT #8 Slag is a clean, small-sized slag aggregate typically ⅜–½ inch. It’s widely used in concrete mixes, asphalt production, and decorative landscaping thanks to its drainage properties and clean appearance.

Best Uses: Concrete mix, asphalt, driveways, drainage beds, landscaping.

INDOT #11 Slag is a finely graded slag aggregate, generally less than ½ inch in size. It’s used in asphalt, pipe bedding, and backfill applications where both compaction and drainage are important.

Best Uses: Asphalt mix, pipe bedding, utility backfill, filler stone.

INDOT #53 Slag blends 1½-inch slag rock with slag fines to create a dense, compactable base material. Its excellent load-bearing strength makes it one of the most popular options for road base, driveways, and parking lots.

Best Uses: Road base, driveways, parking areas, heavy-duty pads.

INDOT #73 Slag is a dense-graded aggregate with smaller particle sizes than #53 (¾" and down with fines). It provides excellent compaction and stability, making it ideal for residential driveways, sidewalks, and patios.

Best Uses: Driveways, walkways, patios, compactable base.

Uniform B Rip Rap (Slag) is a large, durable slag stone used for erosion control and shoreline protection. With consistent sizing, it resists water flow and prevents soil loss in drainage channels, slopes, and embankments.

Best Uses: Shoreline protection, drainage channels, slope stabilization, erosion control.

INDOT #24 Slag Sand is a coarse, clean slag aggregate approved for state and municipal projects. Its durable composition and consistent particle size make it an excellent alternative to natural sand, providing superior drainage and long-term stability. Commonly used in concrete mixes, asphalt production, and bedding applications, this material delivers strength and reliability in both residential and commercial construction.

Best Uses: Concrete mix, asphalt, bedding material, structural backfill.

B Borrow Slag Sand is a cost-effective structural fill material produced from processed slag. Engineered for compaction and load-bearing strength, it’s widely used in embankments, site grading, and utility trench backfill. Its durability and stability make it a dependable choice for large-scale earthwork projects.

Best Uses: Structural backfill, embankments, site grading, utility trenches.
