Abstract The decorative stone processing generates a large amount of stone waste, which is associated with several environmental problems. This paper investigated the potential utilization of the stone waste (mainly containing calcite and dolomite) in the alkali-activated slag based paste backfill (APB). The effects of stone waste fineness, solid mix proportion and sodium hydroxide to sodium silicate ratio (SH/SS) on the fresh and hardened APB were experimentally studied at 7- and 28-day curing time. Results showed that ultra-fine portion (
