In　modern　civil　engineering,　advanced　concrete　materials　are　expected　to　not　only　possess　excellent　mechanical　and　durability　properties　but　also　exhibit　additional　functions.　Waste-derived　artificial　aggregate　(AA)　is　an　innovative　designable　aggregate　type　with　high　sustainability　and　value-added　properties.　This　study　provided　a　comprehensive　literature　review　on　the　functionalization　of　designable　AA　for　the　first　time.　The　intrinsic　characteristics　of　AA　that　are　potential　for　realizing　its　functionalization　were　first　introduced,　where　the　AA＇s　porous　structure　and　chemical　reactivity　were　ideal　for　internal　curing,　self-healing,　purification,　or　foamed　concrete　application.　Then,　the　functionalities　of　AA　through　encapsulating　modification　materials　were　discussed,　where　encapsulating　AA　with　polymers　or　bacteria　could　enhance　self-healing,　combining　AA　with　phase　change　materials　allowed　for　energy　efficiency,　and　adding　additives　like　carbon　fiber　or　magnetite　could　offer　AA　with　conductivity　and　electromagnetic　shielding　characteristics.　Additionally,　the　structural　designs　of　AA　for　improved　functions　were　summarized,　where　core-shell　and　hollow　designs　in　AA　could　improve　heavy　metal　immobilization　and　create　cavities　for　specialized　applications.　Finally,　the　future　perspectives　of　the　AA　functionalization　technology　were　proposed.　The　contributions　of　this　review　could　provide　helpful　guidelines　for　the　future　development,　promotion,　and　practical　applications　of　sustainable　AA　with　additional　functions.
