Production of concretes using slag aggregates ...

2021-12-1  The main by-product of the steel industry is slag. This paper investigates the use of slag aggregates of electric arc furnace (EAFS) and ladle furnace slag (LFS) in replacement of fine and coarse conventional limestone aggregates, for the production of concrete mixtures of C25/30 and C30/37 strength classes (compressive strength of 3625 psi and 4350 psi according to ACI).
