Based　on　the　ultra-high-rise　pumping　concrete　engineering　test　with　pumping　height　of　407　m　and　maximum　pumping　pressure　of　19.3　MPa,　the　variation　of　elastic　modulus　of　the　pumping　concrete　was　analyzed　by　experiments　and　computational　method.　Firstly,　the　back　scattered　electron　(BSE)　image　binarization　method　was　used　to　study　the　effect　of　pumping　on　the　composition　and　pore　distribution　of　the　concrete.　The　effects　of　the　pumping　process　on　the　elastic　modulus　of　the　paste　and　interface　transition　zone　(ITZ)　were　quantitatively　evaluated　by　x-ray　diffraction　(XRD),　back　scattered　electron　energy　dispersive　spectroscopy　(BSE-EDS)　and　homogenization　method,　and　verified　by　the　test　results　of　nanoindentation.　The　results　showed　that　the　porosity　of　the　paste　after　the　ultra-high-rise　pumping　decreased　by　7.27%,　the　hydration　degree　of　the　cement　increased　by　6.51%,　and　the　elastic　modulus　of　the　paste　increased　by　3.1　GPa.　For　the　ITZ　of　the　sand,　the　porosity　decreased　by　5.3　mu　m,　the　average　porosity　decreased　by　15.78%,　and　the　elastic　modulus　increased　by　7.7　GPa.　For　the　ITZ　of　the　gravel,　the　thickness　decreased　by　6.91　mu　m,　the　average　porosity　decreased　by　16.34%,　and　the　elastic　modulus　increased　by　10.2　GPa.　Therefore,　the　effect　of　the　ultra-high-rise　pumping　on　the　ITZ　was　significantly　larger　than　that　of　the　paste　in　the　concrete.　Afterward,　the　computational　method　was　proposed　as　the　combination　of　the　homogenization　method　and　the　Lu　and　Torquato　model.　As　the　result,　the　elastic　modulus　of　concrete　after　ultra-high-rise　pumping　can　be　precisely　predicted　on　the　micro-meso-macro　scale　due　to　the　promising　agreement　between　the　experimental　measurements　and　the　numerical　results.
