In　order　to　provide　a　kind　of　high　performance　filling　material　for　the　lightweight　aggregate　concrete　filled　steel　tube,　the　18　experimental　groups　were　designed　for　the　material　experiment.　The　raw　material　includes　high　strength　cement,　fly　ash,　silica　fume,　expansive　agent,　shale　haydite　and　mixed　fine　aggregate　composed　of　shale　pottery　and　natural　sand.The　high　strength,　lightweight,　slight　expansion　and　self-compacting　concrete　was　prepared.The　influence　law　of　volume　fraction　of　shale　pottery　in　the　mixed　fine　aggregate,　the　amount　of　cementitious　materials　and　the　volume　rate　of　sand　to　concrete　working　performance,　physical　mechanical　properties　and　hardening　deformation　were　comparatively　analyzed.　The　results　show　that:　a)　the　filling　lightweight　aggregate　concrete　of　high　performance　will　be　prepared　for　the　lightweight　aggregate　concrete　filled　steel　tube　by　using　of　the　aforesaid　raw　material;　b)　the　amount　of　the　admixture　and　the　mixed　fine　aggregate　will　be　designed　by　using　of　the　substitute　incorporation　and　the　loose　packing　theory;　c)　the　grain　composition　will　be　modified　by　adjusting　the　volume　ratio　between　the　natural　sand　and　pottery　in　the　mixed　fine　aggregate;　d)　the　proper　cementitious　material　amount　will　be　in　the　range　of　540kg　to　570kg　per　cubic　meter　in　the　concrete;　and　e)the　suitable　value　of　volume　rate　of　the　sand　will　be　about　47%.
