ackfilling　is　often　required　in　the　construction　process　of　pipe　corridors,deep　pits,mining　areas,bridge　culverts,etc.,and　backfilling　with　flowable　filling　materials　is　a　promising　technology.　Flowable　filling　materials　have　significant　differences　in　application　occasions,performance　requirements,construction　methods,material　composition　and　even　terminology　in　different　industries.　Based　on　previous　studies,this　paper　puts　forward　the　concept　of‘low　strength　flowable　filling　materials’and　elaborates　its　basic　characteristics.　At　the　same　time,the　development　and　current　status　of　mine　cemented　fill　materials,controlled　low　strength　materials,and　flowable　solidified　soils　are　reviewed,and　a　relative　distinction　is　made　between　various　types　of　low　strength　flowable　filling　materials　based　on　the　range　of　common　base　material　particle　sizes.　Low　strength　flowable　filling　materials　are　a　class　of　engineering　materials　with　diverse　compositions　and　wide　applications.　They　have　outstanding　inclusiveness　and　green　and　low　carbon　characteristics.　Based　on　this,a　technical　system　for　co-processing　of　various　wastes　can　be　established.　However,at　present,such　materials　have　major　problems　such　as　large　water　consumption,large　differences　in　composition　and　performance,　and　non-uniform　testing　methods.　Therefore,improving　the　performance　of　low　strength　flowable　filling　materials　and　expanding　their　application　fields　are　important　directions　for　the　future　development　of　the　industry.　©　2024　Cailiao　Daobaoshe/　Materials　Review.　All　rights　reserved.
