The　objective　of　this　study　is　to　investigate　the　effect　of　the　steel　fiber　(STF)　contents　(0,　0.5%,　1%　and　2%)　on　the　tensile　basic　creep　behavior　of　lightweight　aggregate　concrete　(LWAC)　during　the　early-age　and　the　overall　14　d.　The　results　showed　that　the　tensile　basic　creep　and　autogenous　shrinkage　of　LWAC　were　both　significantly　reduced　by　adding　STF　and　the　reduction　was　improved　with　the　increase　of　STF　contents.　Moreover,　early　age　contributed　more　than　86%　of　total　tensile　creep　for　all　concretes　during　the　overall　14　d.　Furthermore,　STF　has　a　slight　reduction　on　creep/shrinkage　ratio　(CSR)　during　the　overall　14　d,　regardless　of　any　STF　contents.　In　addition,　the　mechanical　and　microstructural　properties　of　concretes　were　comprehensively　investigated　to　better　understand　the　tensile　basic　creep　behavior　and　autogenous　shrinkage　of　LWAC　with　various　STF　contents.　©　2018　Elsevier　Ltd
