摘要：

Based　on　the　capillary　tension　theory　and　microstructure　pore　of　concrete,　a　prediction　method　of　early　autogenous　shrinkage　of　self-consolidating　concrete　(SCC)　was　established.　Self-consolidating　concrete　(SCC)　specimens　with　different　strength　grades　were　prepared.　The　physical　and　mechanical　properties　(autogenous　shrinkage,　Poisson＇s　ratio,　modulus　of　elasticity　and　compressive　strength)　of　SCC　with　different　strength　grades　were　tested　at　the　age　of　3,7,　and　28　days.　The　3,7　and　28　days　pore　distribution　of　capillary　pores　of　SCC　with　different　strength　grades　were　also　tested.　Negative　pressure　of　capillary　and　autogenous　shrinkage　were　determined　by　means　of　capillary　tension　theory.　Finally,　based　on　the　calculation　results,　a　prediction　method　of　early　autogenous　shrinkage　of　SCC　was　established.　The　results　show　that　predicted　values　derived　from　this　model　matched　very　well　with　measured　values.　(C)　2013　Elsevier　Ltd.　All　rights　reserved.
