Ground blast furnace slag
- the liquid slag is slowly cooled in the open air
- the formed slag has a crystalline structure
- also known as blast furnace slag in pieces
- very compact, with high-strength
- withstands heavy mechanical tension
- dampens mechanical vibrations
- not hazardous
- no harmful effects on the environment
- bulk density: 1.3 t/m3
- Perfectly available for road construction as additive fraction:
at forming filling material, base coat, tie coat and wearing layers - It contains components similar to natural rocks and minerals, therefore, it can get into inorganic structural components of soil, and in contact with water, air, other soil components and the biological system can incorporate into oxides, hydroxides, and clay minerals.
- The pile of stone/slag does not include hazardous substances as per intended use of the final product.
- The slag product meets the requirements under the REACH directive (1907/2006/EC).
- Slag is not considered a hazardous material.
Technology:
- grinding
- screening
