Using　a　shrinkage-restrained　ring　device　with　a　clapboard,　the　effect　of　steel　fiber　content,　sand-binder　ratio　and　water-binder　ratio　on　the　cracking　resistant　behavior　of　reactive　powder　concrete　(RPC)　was　investigated　by　an　orthogonal　experiment.　The　study　results　reveal　that　steel　fiber　content　has　the　most　significant　effect　on　the　cracking　resistant　behavior　of　RPC.　Cracking　ages　and　cracking　coefficients　can　be　used　to　evaluate　the　cracking　resistant　behavior　of　RPC.　The　earlier　crack　age　means　the　poorer　cracking　resistant　behavior　of　RPC,　and　the　higher　cracking　coefficient　denotes　the　poorer　cracking　resistant　behavior　of　RPC.　A　linear　sorting　method　can　be　used　to　approximately　reflect　the　cracking　resistant　behavior　of　RPC.　(C)　2011　Elsevier　Ltd.　All　rights　reserved.
