Production and Use of Blast Furnace Slag Aggregate for Concrete

ten slag with water jet; the former looks like crushed stone and the latter like sand. Coarse aggregate of BF slag for concrete mixing is produced by crushing air-cooled slag and then classifying through screens; fine aggregate is produced by lightly crushing granulated slag to control the grain size and then classifying.

Processes: Air cooling, expanding, pelletizing < Aggregates .

When crushed, air cooled slag is very angular with few elongated pieces. The rough vesicular texture of slag results in a higher surface area as compared to smoother aggregates of equal volume; this rough vesicular surface provides excellent bonding characteristics. Air-cooled blast furnace slag is an extremely versatile.

Slag cement terminology - Slag Cement Association

Air-cooled blast-furnace slag: The material resulting from the solidification of molten blast-furnace slag under atmospheric conditions. Subsequent cooling may be accelerated by application of water to the solidified surface. (This material can be mined and crushed for use as aggregate in concrete or fill materi- al, but is not.

Slag - Wikipedia

Slag is the glass-like by-product left over after a desired metal has been separated (i.e., smelted) from its raw ore. Slag is usually a mixture of metal oxides and silicon dioxide. However, slags can contain metal sulfides and elemental metals. While slags are generally used to remove waste in metal smelting, they can also.
