An ordinary portland cement CEM I 42.5 R conforming to TS EN197-1 was used for producing both artificial slag aggregate (ASA) and concrete. Industrial waste minerals used in the study were Class F FA as mineral admixture in SCCs and GGBFS as the main material in making ASA. The chemical composition of cement, FA, and GGBFS are given in Table 1.

Aggregate is a granular material, such as sand, gravel, crushed stone, crushed hydraulic-cement concrete, or iron blast-furnace slag, used with a hydraulic cementing medium to produce either concrete or mortar. Those particles that are predominantly retained on the 4.75 mm (No. 4) sieve, are called coarse aggregates.
