2020-12-30 Effect of crushed air-cooled blast furnace slag on. Jul 14, 2012 Morphology characteristics of mix aggregates with crushed air-cooled blast furnace slag (SCR) and crushed limestone (LCR) with 5–20 mm and 20–40 mm gradation were represented by numerical parameters including angularity number (AN) and index of aggregate particle shape and texture (IAPST).

Experiences have shown that air-cooled blastfurnace slag lends itself for use in unbound structural pavement layers. The porosity of its grains is attributable to the way in which they are created. They are characterised by a rough surface and a cubic, angular form so that their internal friction coefficient is large and load bearing value higher than that of natural aggregates of the same grain-size distribution.

2017-10-18 Blast furnace slag (BFS) is a by-product from iron production in blast furnaces, which are fed by a mixture of iron-ore, coke and limestone. In the process, the iron ore is reduced to iron while all remaining materials form the slag, which is tapped off as a molten liquid and cooled.
