In　order　to　ascertain　the　fire　resistance　performance　of　recycled　concrete,two　full-sized　concrete　columns　were　designed　and　tested　at　high　temperature　and　unvariable　vertical　load.　One　specimen　was　made　from　normal　concrete　C30,　the　other　was　made　from　the　recycled　coarse　aggregate　concrete　C30.　The　axial　force　ratio　of　the　2　specimens　was　the　same.　Based　on　the　experimental　studies,　aspects,　including　fire　endurance,　temperature　change,　lateral　deflection,　axial　deformation,　and　failure　modes　of　specimens,　were　compared　and　analyzed.　The　simulation　results　in　ABAQUS　show　that　temperature　field　of　the　specimens　＇　cross　section　agreed　quite　well　with　those　from　the　above　experiments,　and　the　coarse　aggregate　concrete　column　has　lower　heating　rate,　higher　fire　resistance　performance,　better　anti-implosion　performance　and　longer　fire　endurance　compared　with　the　normal　concrete　column.　The　reason　is　that　higher　porosity　in　recycled　coarse　aggregate　concrete　can　release　some　inner　steam　stress　in　high　tempreture,　and　result　in　larger　axial　compression　deformation.　So　recycled　coarse　aggregate　concrete　can　be　applied　to　the　building　construction　under　some　condition.
