This article aims to investigate the influence of recycled concrete aggregate (RCA) content on the bond properties between rebar and concrete through pull-out tests. The experimental program involves the preparation of concrete specimens with varying per-centages of recycled aggregates derived from construction and demolition waste, as partial replacements for natural aggregates. The results in terms of bond-slip law are compared with those of conventional concrete with natural aggregates, providing a basis for evaluating the performance of recycled aggregate concrete. The study seeks to shed light on the viability and potential of in-corporating RCA in concrete mixes while evaluating its impact on bond strength and overall performance. The findings will pro-vide valuable insights into sustainable construction practices, by promoting the use of recycled materials in the concrete industry.

Abstract
This article aims to investigate the influence of recycled concrete aggregate (RCA) content on the bond properties between rebar and concrete through pull-out tests. The experimental program involves the preparation of concrete specimens with varying per-centages of recycled aggregates derived from construction and demolition waste, as partial replacements for natural aggregates. The results in terms of bond-slip law are compared with those of conventional concrete with natural aggregates, providing a basis for evaluating the performance of recycled aggregate concrete. The study seeks to shed light on the viability and potential of in-corporating RCA in concrete mixes while evaluating its impact on bond strength and overall performance. The findings will pro-vide valuable insights into sustainable construction practices, by promoting the use of recycled materials in the concrete industry.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
