Fly　ash　(FA),　silica　fume　(SF),　and　blast　furnace　slag　(BFS)　were　used　as　the　supplementary　cementitious　materials　(SCMs)　in　cement　paste.　The　axial　tensile　strength,　ultimate　strain　and　the　area　of　fracture　surface　of　cement　paste　with　SCMs　were　experimentally　investigated　in　this　study,　and　the　relationship　between　tensile　strength　and　fracture　area　of　specimens　were　analyzed.　The　test　results　show　that　the　tensile　strength　of　the　specimens　decreases　with　the　increasing　addition　of　SCM.　Except　for　SF,　there　is　a　negative　correlation　between　the　tensile　strengths　of　specimens　and　W/B　ratio.　The　increasing　dosage　of　BFS,　FA,　and　SF　improves　the　ultimate　strain.　The　fracture　area　of　cement　paste　decreases　with　an　increase　in　water-binder　(W/B)　ratio.　The　total　fracture　area　is　relatively　large,　as　the　tensile　strength　value　is　relatively　low.
