The　effects　of　carbon　nanotubes　(CNTs)　on　autogenous　shrinkage　of　cement　paste　were　explored.　The　additions　of　CNTs　were　0.025%-0.125%　of　cement　by　mass.　Results　showed　that　the　autogenous　shrinkage　of　cement　paste　with　0.05%　CNTs　was　lowest,　22.1%　lower　than　PC.　The　autogenous　shrinkages　of　CNTs　blended　cements　were　predicted　based　on　the　poroelastic　model　and　poroviscoelastic　model,　respectively.　The　root　mean　square　error　(RMSE)　of　autogenous　shrinkage　prediction　based　on　poroelastic　model　was　3　times　higher　than　that　of　poroviscoelastic　model,　which　indicated　that　poroviscoelastic　model　was　more　appropriate　for　predicting　the　autogenous　shrinkage　of　CNTs-cement　paste.　The　role　of　CNTs　on　shrinkage　mitigation　were　analyzed　by　combination　with　microscopic　tests　and　prediction　results.　Results　indicated　that　CNTs　possess　distinctive　mitigation　effects　at　different　curing　ages,　which　were　related　to　the　CNTs　contents.
