The　influence　of　mineral　admixture　on　the　drying　shrinkage　of　high　performance　concrete　(denoted　as　HPC)　was　studied.　The　results　are　as　fellows.　When　the　content　of　fly　ash　lower　than　20%　of　binder,　the　drying　shrinkage　of　HPC　decreases　with　the　increasing　of　fly　ash　content.　The　drying　shrinkage　of　HPC　with　metakaoli　and　fly　ash　is　higher　than　that　only　with　fly　ash.　And　the　combination　of　fly　ash　and　slag　may　decrease　the　drying　shrinkage　of　HPC,　and　the　drying　shrinkage　of　concrete　with　1:　1　of　the　proportions　of　slag-fly　ash　is　the　lowest.　Compare　the　existing　calculation　model　of　drying　shrinkage　of　concrete　with　the　test　data,　the　calculation　model　of　drying　shrinkage　of　HPC　was　put　forward.　In　contrast　with　the　test　results,　the　calculation　model　fitted　the　data　well.
