Blast furnace slag is the non-metallic product consisting essentially of silicates and aluminosilicates of calcium and other bases, which is developed in a molten condition simultaneously with iron in a blast furnace.
Air-cooled blast furnace (ABF) slag is a predominantly crystalline, solid rock-like material.

Crusher dust is a grey coloured fine aggregate consisting of angular to roughly cubical shaped particles with a characteristically vesicular structure and rough surface texture.
All types of construction including:
- General fill and paving sand
- Refractory sand
- Concrete, cement and masonry raw material
- Resistant to heat and fire
- Alkaline in presence of moisture
- Non-plastic
- Consistent chemistry
- Excellent load bearing capacity
- High stability and durability
- Ease of compaction
