It brings a series problem of nature resources, pollution of t e environment , energy con- sume and t e problem of continuable development w ile toring dow n t e old building produced a large scale of building garbage, 3 but used for t e concrete to build deplet ion undred million m natural aggregate annually. To alleviate t is contradiction, t e development and applicat ion study of recycled aggregate and recycled concrete received extensive concern, become one of t e key tec niques to be solved. But t at tec nical researc of our country is still in lab experiment researc stage because it started t an later. We analyzed t e current researc condit
