Air-Cooled Blast Furnace Slag is produced by Tata Steel IBMD, through slow solidification of molten blast furnace slag under atmospheric conditions, which results in a crystalline and vesicular structure.
Air-Cooled Blast Furnace Slag is hard but can be crushed and screened.
Air-Cooled Blast Furnace Slag is formed from solidification of molten blast furnace slag in a slag pit under atmospheric conditions with some spraying of water to accelerate cooling so the materials can be moved to the processing plant.
Due to slow cooling rate, Air-Cooled Blast Furnace Slag forms a crystalline structure, which may contain some glassy and dense particles that can be crushed to produce an angular coarse aggregate.
Mineral wool is a high-quality, versatile fiber suitable for a variety of applications, including ceiling tiles, insulation, asphalt, cementitious reinforcement, friction products, fire protection systems, adhesives and fillers.
Air-Cooled Blast Furnace Slag aggregate demonstrates good friction resistance, good resistance to stripping, and better wear resistance. ACBF is also included in Indian Standards (IS Codes) for using it as a replacement of natural aggregates in different pavement layers.
Apart from the above applications, Air-Cooled Blast Furnace Slag can also be used as an aggregate in light-weight concrete.
