Air Cooled Blast Furnace Slag

Air-Cooled Blast Furnace Slag (ACBF) is generated through slower solidification of molten blast furnace slag under atmospheric conditions which produces a crystalline and vesicular structure. ACBF is a non-metallic product that is developed in a molten condition simultaneously with iron in a blast furnace.

Air-Cooled Blast Furnace Slag is hard but can be crushed and screened easily. The resultant material can be crushed to produce an angular and roughly cubical coarse aggregate which can be used in many segments of highway construction including base courses, fill and embankments etc.

It is the innate properties of ACBF that make it an ideal replacement of coarse aggregates for road making.

The initiative by the Industrial By-Product Management Division (IBMD) of Tata Steel as a coarse aggregate supplier in Jharkhand and Odisha has helped in development of road applications and also reduce or elimination of solid waste.

Some of the salient features of ACBF manufactured by Tata Steel are:

  1. It is available in angular, cubical vesicular form
  2. The glass content of ACBF varies from 20% - 30%
  3. It has a rough surface texture giving good frictional properties and good adhesion to bituminous and cement binders
  4. It has low coefficient of thermal expansion, making it fire resistant


Raw material for Mineral Wool

Coarse Aggregate in Road Making

Coarse Aggregate in Road Making

Air-Cooled Blast Furnace Slag is widely used in road making as a substitute of coarse aggregates. The product is approved as per Indian Standards (IS Codes) for using it as a replacement of natural aggregates in different layers of the road pavements.

ACBF from Tata Steel is superior in quality - demonstrating good resistance to friction, has better stripping resistance and wear resistance making it an ideal choice for road making.

As a coarse aggregate supplier in Jharkhand and Odisha, Tata Steel has been proudly associated in development of 2 National Highways near Jamshedpur, National Highway 33 and 32 where the ACBF has been extensively used.
