All slag–cement–bentonite mixes were prepared in a lab mixer with a rotational speed of 190 rpm. The bentonite was first mixed with water for ten minutes to ensure the formation of a uniform bentonite slurry. The bentonite slurry was then left to hydrate for 24 h, after which the dry cement, GGBS and SEBS were added.
