This　study　aims　to　investigate　the　effect　of　pre-wetting　lightweight　aggregate　(LWA)　on　the　tensile　creep　of　alkali　-activated　slag　concrete　(AASC)　for　14　d.　Three　replacement　rates　of　natural　coarse　aggregate　with　LWA　were　used　in　this　study,　including　0,　50%,　and　100%,　and　the　Ordinary　Portland　cement　concretes　(OPCCs)　mixed　with　LWAs　were　considered　as　control　samples.　The　results　showed　that　the　tensile　creep　of　the　AASCs　was　higher　than　those　of　OPCCs　with　the　same　LWA　content.　The　incorporation　of　pre-wetting　LWA　significantly　reduced　the　modified　autogenous　shrinkage　and　tensile　creep　of　the　AASCs,　and　the　magnitudes　were　continuously　declined　with　the　increase　in　LWA　contents.　The　early　age　of　1　d　dominated　more　than　70%　of　the　total　tensile　creep　of　the　AASCs　for　14　d.　Furthermore,　pre-wetting　LWAs　had　a　greater　effect　on　decreasing　tensile　creep　for　the　AASC　system　than　the　OPCC　system.　Meanwhile,　the　creep/shrinkage　ratio　of　the　AASCs　was　declined　by　the　addition　of　pre-wetting　LWAs.　In　addition,　the　cracking　age　of　the　AASC　was　desirably　delayed　by　adding　pre-wetting　LWA,　and　the　effect　was　more　noticeable　with　the　increase　in　LWA　contents.
