Bond performance of deformed steel bars in concrete produced with coarse recycled concrete aggregate

Results of an experimental study on the bond performance of deformed steel rebars in concrete made with coarse recycled concrete aggregate (RCA) are presented. The distinctive feature of the study is the new mix proportioning method for RCA concrete that results in the strength to elastic modulus ratio (f′c/Ec) similar to a conventional concrete having the same amount of total mortar and coarse aggregate. In this method, the properties and …
