With　the　rapid　development　of　soil-cement　application　technology,　soil-cement　is　widely　applied　in　mine　development,　such　as　mine　road　construction,　pit　repair,　stope　reinforcement　and　mine　backfill,　etc.　In　this　paper,　ferronickel　slag　powder　and　mineral　powder　are　applied　in　soil-cement　to　study　the　impact　of　their　content　on　the　strength　performance　of　soil-cement.　The　results　show　that　the　addition　of　ferronickel　slag　powder　has　a　greater　impact　on　the　strength　of　soil-cement　at　the　early　age.　However,　with　the　increase　of　age,　the　strength　decrease　rate　of　soil-cement　with　ferronickel　slag　powder　reduces.　When　ferronickel　slag　powder　and　granulated　blast　furnace　slag　are　mixed,　the　performance　of　soil-cement　at　the　early　age　is　better　than　that　with　ferronickel　slag　powder　alone.　The　optimal　combination　is　that　ferronickel　slag　powder　accounts　for　20%,　among　which　the　mineral　powder　replaces　30%　of　the　ferronickel　slag　powder　mass.　Copyright　©　2020　Inderscience　Enterprises　Ltd.
