This　article　researched　the　influence　of　microwave　pre-curing　on　the　creep　properties　of　cement　pastes.　Microwave　pre-curing　with　different　durations　was　performed　on　cement　paste　specimens　after　standard　cured　for　3　d.　Subsequently,　the　creep　performance　of　the　cement　paste　and　the　phase　was　acquired　using　indentation　tests.　The　quantitative　analysis　of　the　phase　was　performed　on　the　cement　paste　specimens　after　microwave　pre-curing.　The　reasons　for　the　variation　of　creep　properties　of　the　specimens　affected　by　microwave　pre-curing　were　also　analyzed　based　on　the　pore　characteristics,　gel　structure,　and　dielectric　properties.　The　results　indicated　that　the　creep　modulus　of　cement　paste　samples　gradually　increased　with　the　increase　of　microwave　pre-curing　time.　Microwave　pre-curing　significantly　enhanced　the　contact　creep　modulus　(CCM)　of　low-density　(LD)　C-S-H　gel　and　high-density　(HD)　C-S-H　gel.　With　the　increase　of　microwave　pre-curing　time,　the　porosity　in　the　samples　decreased　and　the　pore　structure　was　significantly　improved.　Microwave　pre-curing　decreased　the　percentage　of　LD　C-S-H　gel　and　significantly　increased　the　percentage　of　HD　C-S-H　gel,　and　also　increased　the　complex　structure　of　C-S-H　gel.　Microwave　pre-curing　enhanced　the　dielectric　performance　of　paste　specimens　and　increased　their　ability　to　store　and　absorb　electromagnetic　waves.
