Recycling ground granulated blast furnace slag as cold bonded artificial aggregate partially used in self-compacting concrete

► Artificial slag aggregates (ASA) were produced via cold bonding pelletization technique. ► Natural coarse aggregates were replaced with ASA in making self compacting concrete (SCC). ► Fresh properties of SCC were evaluated in terms of flowability, viscosity and passing ability. ► ASA was proved to be suitable for utilization in production of SCC. ► SCC characteristics appeared to improve as ASA was used.
