Bond and Cracking Behavior of Reinforced Concrete Members Incorporating Recycled Aggregates

The aim of the present work is to investigate the bond strength and cracking properties of recycled aggregate concretes (RAC). For this purpose, six recycled concrete aggregate mixtures and two conventional concrete mixtures with C25/30 and C35/45 target class of compressive strength and S4 class of workability were chosen. For both series, specimens were fabricated with different incorporation ratios of fine and coarse recycled aggregates and only coarse recycled aggregates.
