Dolomite　rock　powder　(the　waste　stone　residue　in　the　production　of　machine-made　sand　and　stone　processing)　and　iron　tailings　powder　formed　by　mineral　processing　industry　are　solid　wastes,　which　occupy　land　resources,　pollute　the　environment　and　release　toxic　substances　without　reasonable　processing.　The　dolomite　rock　powder　and　iron　tailings　powder　composing　a　large　number　of　active　substances　could　be　advantageous　to　the　cement-based　materials.　In　this　study,　the　electrical　resistivity　of　cement　paste　and　concrete　was　measured.　Meanwhile,　the　influence　of　dolomite　rock　powder　and　iron　tailings　powder　on　the　compressive　strength　of　concrete　was　investigated.　The　electric　flux　of　concrete　was　determined　to　estimate　the　chloride　ion　permeability.　The　scanning　electron　microscope　(SEM)　and　X-ray　diffraction　were　obtained　to　investigate　the　hydration　of　cement　paste.　Results　showed　the　electrical　resistivity　of　all　specimens　presented　in　this　order:　specimens　with　iron　tailings　＜　specimens　with　dolomite　rock　powder　＜　blank　specimens　＜　specimens　with　ground　granulated　blast-furnace　slag　(GGBS)　＜　specimens　with　fly　ash.　The　correlation　between　electrical　resistivity　and　curing　age　of　cement　paste　or　concrete　has　been　deduced　as　a　quadratic　function.　The　addition　of　GGBS　could　improve　the　compressive　strength　of　concrete.　Meanwhile,　when　the　other　three　types　of　mineral　admixtures　were　added,　5%　by　mass　ratio　of　the　total　binder　materials　was　the　optimum　for　the　compressive　strength.　The　curing　ages,　the　fly　ash,　the　GGBS　and　5%　dolomite　rock　powder　or　5%　iron　tailings　powder　demonstrated　a　positive　effect　on　the　chloride　ion　impermeability.　However,　when　higher　dosages　of　dolomite　rock　powder　or　iron　tailings　powder　were　added,　the　effect　was　the　opposite.　Finally,　the　compactness　of　the　microstructure　and　the　Ca(OH)(2)　of　cement　paste　could　be　improved　by　a　small　dosage　of　dolomites　or　iron　tailings　(less　than　5%).
