Fly　ash　(FA),　silica　fume　(SF),　and　ground　blast　furnace　slag　(GBFS)　were　used　as　the　supplementary　cementitious　materials　(SCMs)　in　cement　paste.　The　autogenous　shrinkage　(AS)　and　the　shrinkage　cracks　of　cement　paste　with　SCMs　were　experimentally　investigated　in　this　study,　and　the　relationship　of　AS,　tensile　strength,　and　crack　area　of　cement　paste　were　analyzed.　The　test　results　show　that　FA　decreases　the　AS　of　cement　paste　and　SF　increases　the　AS.　Both　the　AS　and　the　crack　area　of　cement　paste　decrease　with　the　increase　of　the　water-binder　(W/B)　ratio.　When　W/B　ratios　of　different　cement　pastes　are　kept　the　same,　the　tensile　strength　of　cement　paste　is　not　influenced　by　the　AS　if　the　specimens　can　shrink　freely.　Equations　are　established　to　describe　the　relationship　among　AS,　tensile　strength,　and　crack　area　of　the　cement　paste　with　SCMs.　DOI:　10.1061/(ASCE)MT.1943-5533.0000501.　(C)　2012　American　Society　of　Civil　Engineers.
