Can Steel Slag be used as an Aggregate in Concrete and How ...
For steel slag used as a coarse aggregate in portland cement concrete, the resulting integrity and volume stability are basically controlled by the allowable stress of the matrix materials, cement mortar for instance, and the expansion stress. A usability criterion for steel slag use in confined conditions can be

In concrete mix design specifications that specify minimum cement content or maximum water, the cement ratios could potentially unfairly discriminate against the use of coal fly ash or GGBF slag. Such specifications should be changed in order to allow the partial substitution of coal fly ash or GGBF slag for cement in the concrete mixture ...

Almost all GGBFS is used as a partial substitute for portland cement in concrete mixes or in blended cements. Pelletized slag is generally used for lightweight aggregate but can be ground into material similar to GGBFS.

Portland cement blends are often available as interground mixtures from cement producers, but similar formulations are often also mixed from the ground components at the concrete mixing plant. [30] Portland blastfurnace slag cement, or Blast furnace cement (ASTM C595 and EN 1971 nomenclature respectively), contains up to 95% ground granulated blast furnace slag, with the rest Portland clinker .

Two possible uses of this type of slag are suggested in the literature: as a pozzolanic admixture to cement, after fine grinding (over cm^g Blaine (1); as a substitute for sand, taking advantage of the fact that their particle sizes are generally very similar to the fine fraction of aggregates used in concrete manufacture (18).
