Abstract：

A　three-phase　micromechanical　model　for　the　healed　saturated　concrete　is　presented,　which　is　made　up　of　the　deposition　products,　water　and　intrinsic　concrete.　A　multi-level　homogenization　scheme　is　developed　to　obtain　the　effective　properties　of　the　saturated　concrete　repaired　by　electrochemical　deposition　method　based　on　the　Mori-Tanaka　method.　Specifically,　the　properties　of　the　equivalent　inclusion　are　calculated　by　Mori-Tanaka　method　with　modification　function　in　the　first　level　homogenization.　In　the　second　level　homogenization,　the　Mori-Tanaka　method　is　utilized　to　obtain　the　properties　of　the　repaired　concrete.　The　homogenized　three-phase　micromechanical　model　is　utilized　to　predict　the　effective　properties　of　the　saturated　concrete　repaired　by　electrochemical　deposition　method.　And　the　predicted　results　are　compared　with　the　experimental　data　and　the　existing　models.　Comparisons　show　that　the　proposed　model　can　effectively　predict　the　effective　properties　of　saturated　concrete　repaired　by　electrochemical　deposition　method.　When　there　is　no　repairing,　they　can　predict　the　Young＇s　modulus　of　saturated　concrete.　Based　on　the　proposed　micromechanical　framework,　it　is　found　that　the　healed　specimens　have　better　performance　when　the　deposition　products　exhibit　higher　properties.　©,　2014,　Science　Press.　All　right　reserved.
