In　order　to　increase　the　strength　and　lower　the　cost,　this　study　experimentally　investigated　the　effects　of　hooked-end　steel　fiber,　basalt　fiber　and　calcium　sulfate　on　mechanical　performance　of　polyvinyl　alcohol　(PVA)　fiber-based　engineered　cementitious　composite　(ECC)　containing　high-volume　fly　ash.　The　uniaxial　tensile,　compression　and　four-point　bending　tests　were　carried　out　to　characterize　the　mechanical　behavior　of　each　mixture.　Scanning　Electron　Microscopy　(SEM)　image　analysis　and　X-ray　CT　scan　method　were　used　to　study　the　micro-structures　and　distributions　of　pores.　Test　results　showed　that　the　ultimate　strain　capacity　increases　nearly　linearly　with　the　growth　of　stress　performance　index　except　the　ECC　reinforced　with　calcium　sulfate　and　PVA.　Hybridization　with　basalt　fiber　and　PVA　fiber　or　steel　fiber　and　PVA　fiber　is　more　effective　for　improving　mechanical　performance　within　small　deformation.　ECC　reinforced　with　calcium　sulfate　and　PVA　exhibits　improved　tensile,　compressive　and　flexural　strength　while　maintaining　high　ductility.　The　cost　performance　considering　strength/cost　and　ductility/cost　of　hybrid　mixtures　was　also　discussed.
