Experimental study on the bond - slip behavior of lightweight concrete using recycled light aggregates

Abstract

Advanced technologies have been developed to produce lightweight aggregate from construction and demolition wastes, which allow to reduce the use of the limited natural resources. In this paper, the author present experimental research on the bond-slip behavior of lightweight concrete using recycled lightweight aggregate. Pullout tests were carried out to determine the bonding and propose the bond-slip relationship between recycled lightweight concrete and steel bar. This provides essential groundwork for analyzing the performance of reinforced concrete structures using lightweight concrete with recycled lightweight aggregates.
