Slag

Slag aggregates are a sustainable and versatile material derived from the byproduct of steel production. When iron ore or scrap metal is melted to produce steel, slag is formed as a result of the impurities and fluxes present in the raw materials. This slag is then cooled and processed into various sizes of aggregates suitable for a wide range of applications. Commonly used in: Road construction and maintenance, Railroad ballast, Concrete production, Asphalt mixtures, Soil stabilization, Landfill cover materials, Abrasive blasting

#2 Slag: Has been graded to pass through a sieve with apertures of 2 inches (50 mm) in diameter. It is coarser in size and may be used for applications such as road base, fill material, or drainage aggregate.

#8 Slag: This designation indicates slag aggregate that has been graded to pass through a sieve with apertures of 3/8 inch (9.5 mm) in diameter. It is finer in size compared to #2 slag and may be suitable for use in concrete mixes, asphalt mixes, or as a drainage material.

#53 Slag: The number 53 signifies that the aggregate passes through a sieve with apertures of 1/2 inch (12.5 mm) in diameter and is retained on a sieve with apertures of 3/8 inch (9.5 mm) in diameter. This size of slag aggregate is commonly used in concrete production, road construction, and landscaping.

#73 Slag: This designation indicates slag aggregate that has been graded to pass through a sieve with apertures of 3/4 inch (19.0 mm) in diameter. It is coarser than #53 slag and may be used for similar applications such as concrete production, road base, or fill materials.

These aggregates offer several advantages, including:

Durability: Slag aggregates possess excellent durability and resistance to wear and tear, making them ideal for use in high-traffic areas such as roads, highways, and railways.
Strength: Due to its angular shape and interlocking properties, slag aggregates provide excellent load-bearing capacity, enhancing the structural integrity of construction projects.
Environmental Sustainability: Utilizing slag aggregates helps to reduce the environmental impact of steel production by diverting waste from landfills and conserving natural resources. Additionally, incorporating slag into construction projects can potentially contribute to green building initiatives and LEED certification.
Cost-effectiveness: Slag aggregates are often more cost-effective than traditional natural aggregates, offering a competitive alternative for various construction applications.

Overall, slag aggregates provide a sustainable and high-performance solution for construction and infrastructure projects while offering economic and environmental benefits.
