This　research　studies　the　durability　of　self-compacting　concrete　(SCC)　with　fly　ash　(FA),　coal　gangue　powder　(CGP),　cement　kiln　dust　(CKD),　and　recycled　concrete　powder　(RCP)　by　absolute　volume　method.　The　fresh　properties　of　self-compacting　concrete　(SCC)　mixtures　were　assessed　by　slump　flow,　T50　cm　slump　flow,　and　V-Funnel　flow　time.　The　strength　and　durability　properties　were　evaluated　using　a　compressive　strength　test,　Freeze-thaw　resistance,　chloride　ion　penetration,　and　carbonation　resistance　tests.　Furthermore,　the　pore　structure　of　concrete　after　a　90-day　curing　period　was　analyzed　using　Mercury　Intrusion　Porosimetry　(MIP),　which　provided　valuable　information　on　the　distribution　and　properties　of　pores　inside　the　material.　The　results　revealed　that　SCC　with　FA　and　CKD　performed　best　with　a　slump　flow　of　700　mm.　Specimens　with　FA　and　RCP　have　greater　compressive　strength　after　90　days　of　curing,　making　them　appropriate　for　high-strength　applications.　In　terms　of　freeze-thaw　resistance,　SCC　with　CGP　exhibits　the　lowest　mass　loss　rate,　indicating　the　best　resistance,　followed　by　FA　and　CKD,　with　RCP　showing　the　least　resistance.　FA　and　CKD　have　excellent　enhancement　effects　for　SCC　resistance　to　chloride　ions.　Specimens　with　RCP　have　the　lowest　carbonation　depth　and　the　best　carbonation　resistance.　The　findings　suggest　that　the　concrete　specimens　with　fly　ash　(FA)　have　the　highest　total　pore　area　and　porosity,　with　a　wide　range　of　pore　sizes　and　a　prominent　peak　in　the　capillary　pore　size　range,　indicating　a　highly　porous　structure.　This　study　provides　practical　advice　on　how　to　use　SCC　in　construction　and　improve　material　selection　and　optimization.
