To　study　the　effects　of　mineral　admixtures　on　the　autogenous　shrinkage　of　high-performance　concrete　(HPC),　the　non-contact　automatic　testing　device　was　used　to　test　the　autogenous　shrinkage　of　HPC.　It　can　be　concluded　that,　the　autogenous　shrinkage　of　HPC　decreases　with　the　increase　of　the　content　or　the　quality　of　fly　ash.　The　autogenous　shrinkage　of　HPC　mixed　with　metakaoli　and　fly　ash　is　higher　than　HPC　only　with　fly　ash.　However,　the　mixing　of　fly　ash　and　slag　may　reduce　the　autogenous　shrinkage　of　HPC.　And,　the　optimal　proportion　of　slag-fly　ash　to　minimize　the　autogenous　shrinkage　of　HPC　is　1:1.　Based　on　reviewing　the　existing　computation　model　of　autogenous　shrinkage　of　concrete,　a　HPC　autogenous　shrinkage　computation　model　is　suggested　using　testing　data.　The　analytical　results　fit　well　with　test　results.
