The　factors　that　affect　the　autogenous　shrinkage　and　drying　shrinkage　of　recycled　concrete　were　studied,　including　different　recycled　coarse　aggregate　replacement　rates(by　mass)　and　pretreatment　methods.　The　experimental　results　show　that　the　shrinkage　strain　of　recycled　concrete　is　greater　than　that　of　normal　concrete　in　the　same　condition,　and　the　shrinkage　strain　of　recycled　concrete　increases　with　the　increase　of　recycled　coarse　aggregate　replacement　rate.　By　using　appropriate　pretreatment　methods,　the　shrinkage　strain　of　recycled　concrete　can　be　greatly　reduced.　The　effects　of　the　same　pretreatment　method　on　the　autogenous　shrinkage　and　drying　shrinkage　are　different.　As　for　autogenous　shrinkage,　pre-wet　method　is　the　best　by　which　the　autogenous　shrinkage　strain　of　recycled　concrete　can　be　about　30.0%　lower,　and　aggregates　coated　with　cement　is　the　next　best　method.　However,the　autogenous　shrinkage　strain　of　recycled　concrete　increases　by　using　aggregates　coated　with　cement　and　adding　silica　fume.　As　for　drying　shrinkage,　aggregates　coated　with　cement　and　adding　silica　fume　is　the　most　effective　way　by　which　the　drying　shrinkage　strain　of　recycled　concrete　can　be　reduced　by　about　15.0%,　aggregates　coated　with　cement　is　the　second　best　method,　and　pre-wet　method　comes　last.　Different　pretreatment　methods　can　be　selected　according　to　the　different　type　of　recycled　concrete　components　and　their　shrinkage　characteristics　in　practical　application　to　make　sure　the　autogenous　shrinkage　and　drying　shrinkage　of　recycled　concrete　is　close　to　that　of　normal　concrete.　©　2016,　Editorial　Department　of　Journal　of　Building　Materials.　All　right　reserved.
