摘要：

Based　on　the　basic　principles　for　producing　Reactive　Powder　Concrete　(RPC),　a　new　kind　of　RPC　with　compositions　of　superfine　cement,　Portland　cement,　admixtures　(ground　granulated　blast　furnace　slag　and　fly　ash),　sand,　water,　superplasticizer,　steel　fibers,　without　silica　fume　was　produced　and　tested.　Experiment　results　show　that　it　is　feasible　to　produce　RPC　without　the　admixture　of　silica　fume.　The　strength,　fluidity　and　cost　of　RPC　are　satisfied　with　appropriate　proportion　of　superfine　cement　and　admixtures.　The　superfine　cement　in　RPC　can　be　partly　replaced　by　Portland　cement　to　reduce　the　cost.　The　effect　of　the　amount　of　steel　fibers　on　the　mechanical　properties,　such　as　compression　resistance,　breaking　resistance,　fluidity　and　flexural　toughness,　of　the　RPC　was　analyzed.
