Eolit Slag 2–5 mm
Eolit slag 2–5 mm — electric arc furnace slag in fine grading — is the high-performance industrial aggregate that outperforms most natural rock in load-bearing applications. Produced as a carefully treated byproduct of steel manufacturing, this material has a density roughly 25% higher than typical natural gravel and a hardness that resists abrasion under heavy mechanical load. Compliant with the German FGSV regulations for slag aggregates in road construction, it is the right choice when sub-base performance matters more than appearance.
Features and benefits
The defining technical advantage of Eolit slag 2–5 mm is its extreme polished stone value and crushing resistance — the angular, rough-surfaced grains lock into a sub-base that simply does not deform under load. It is fully frost-resistant, environmentally certified for use as construction material, and offers an excellent bearing capacity contribution to compacted layers.
Areas of application
Use Eolit slag 2–5 mm as a leveling and locking layer over heavy-load sub-bases in industrial yards, logistics areas, container storage pads, and farm tracks. It is the standard top fraction beneath asphalt in road construction, and the fill material of choice for gabion baskets where weight and structural mass matter. In civil engineering it serves as bedding under heavy concrete elements and as a stable surfacing layer for forestry and industrial paths.
Expert tip on processing
Always handle Eolit slag separately from natural stone — the dark, dense grains can stain light-colored adjacent paving if mixed carelessly. Compact in 10 cm lifts with a vibration plate, and finish with a light water pass to lock the surface. For decorative or residential settings, choose natural stone instead; Eolit slag belongs where performance, not appearance, drives the spec.
