Reactive　powder　concrete　(RPC)　is　a　kind　of　cement-based　composite　which　has　ultra-high　strength.　It　owns　super　high　mechanical　performances,　excellent　durability,　lower　shrinkage　and　creep　performances.　Based　on　the　compressive　experiments　of　28　groups　of　cubes　and　14　groups　of　prism　specimens,　split　and　pull　strength　experiment　of　40　groups　of　carbon　fiber　RPC　with　different　size　and　flexural　strength　experiment　of　20　groups　of　cube　specimens　with　40mm　x　40mm　x　160mm.　This　paper　discusses　the　physical　and　mechanical　properties　such　as　the　cube　compressive　strength,　the　split　and　pull　strength,　the　flexural　strength,　the　effect　of　size,　the　prism　compressive　strength,　Young＇s　modulus　and　peak　strain　etc　of　the　carbon　fiber　RPC　with　different　curing　methods　and　different　volume　fractions　of　steel　fiber.　Finally,　the　mechanism　effect　of　carbon　fiber　by　observing　the　failure　phenomenon　of　cube　specimens　is　introduced.
