In　order　to　investigate　the　bond-slip　behavior　between　steel　bars　and　recycled　concrete,　the　bond-slip　properties　of　13　reinforced　medium/high　strength　recycled　concrete　beam-type　specimens　were　tested.　The　effects　of　the　shape　of　steel　bar,　the　length　of　anchorage,　the　strength　of　concrete　and　the　replacement　ratio　of　recycled　aggregate　on　the　bond-slip　behavior　between　steel　bars　and　recycled　concrete　were　studied.　Research　shows　that:　when　the　recycled　coarse　aggregate　replacement　is　33%~66%　and　the　fine　aggregate　is　natural　sand,　the　bond　strength　between　steel　bar　and　recycled　concrete　is　basically　coincident　with　ordinary　concrete.　When　the　replacement　rate　of　recycled　coarse　aggregate　is　100%　and　the　fine　aggregate　is　over　50%,　the　bond　behavior　between　rebars　and　recycled　concrete　is　degraded　distinctly.　Compared　with　the　ordinary　concrete　specimens,　the　bond　efficiency　coefficient　of　the　relative　concrete　strength　of　the　recycled　coarse　aggregate　concrete　specimens　is　higher.　The　bond　strength　between　deformed　bars　and　recycled　concrete　is　better　than　plain　ones.　The　bond　strength　between　steel　and　recycled　concrete　decreases　with　the　increase　of　the　anchorage　length　of　reinforcement.　The　calculated　values　of　the　fitted　bond-slip　constitutive　model　agree　with　the　experimental　values　well.　©　2017,　Editorial　Office　of　Journal　of　Building　Structures.　All　right　reserved.
