The　effects　of　restrained　shrinkage　on　adhesion　was　modeled　with　the　finite　element　program　ABAQUS.　The　results　were　compared　to　adhesion　tests　between　old,　cured　concrete　and　fresh　self-compacting　concrete.　The　finite　element　model　was　shown　to　be　correct.　The　stress　distribution　is　affected　by　restrained　shrinkage　and　this,　in　turn,　affects　adhesion.　A　tensile　stress　is　obvious　in　the　new　concrete　layer　near　the　interface.　Further　from　the　interface　the　tensile　stress　decreases　until　the　stress　finally　becomes　compressive.　Maximum　shear　stress　appears　at　either　end　of　the　specimen　with　a　shear-stress　minimum　in　the　middle.　Thinner　layers　in　the　new,　repair　layer　result　in　larger　shrinkage　induced　tensile　stresses.　The　tensile　strength　is　minimized　when　the　H/L　of　the　new　layer　is　1/4.
