In the first stage of the experimental program artificial slag aggregates (ASA) were produced through the cold bonding agglomeration process of ground granulated blast furnace slag and Portland cement in a tilted pan at an ambient temperature. For this, 10% PC and 90% GGBFS were mixed in powder form in the …

Hydraulic cement concretes were produced using pozzolans and ground, granulated, blast-furnace slag (slag) to investigate the effect of these materials on durability. The pozzolans used were an ASTM C 618 Class F fly ash with a low lime content and a dry, densified silica fume. The slag was an ASTM C 989 Grade 120 material.

Blast furnace slag is an industrial by-product resulting from ion production, and it consists primarily of silicates, and aluminate and calcium [25]. In order to broaden the application range, the original granules with large-sizes are always grounded to fine particles, known as ground granulated blast furnace slag [25].

After completing the transformation process, these wastes were obtained in the range of 0–6, 6–12, and 12–19 mm. Also, the slag type used in this research was granulated blast furnace slag (GBS), which was extracted from Esfahan Steel Company, Iran. The grain size distributions of clay soil and RCA are shown in Fig. 1.
