Preparation of alkali-activated steel slag-fly ash based full solid waste filling material and strength formation mechanism research

To utilize steel slag solid waste resources, this study developed a fully solid-waste-based cemented coal backfill material using alkali-activated steel slag-fly ash cementitious material as a cement substitute and coal gangue as aggregate. The effects of activator (Na2SiO3) modulus and alkali conce...
