Analytical investigation in bond of deformed steel bars in recycled aggregate concrete
Theoretical analysis of bond in RAC has been carried out using the thick-cylinder analogy and the calculated results are compared with the experimental results from the unconfined 132 splice beam specimens tested under four-point bending. The parameters for this investigation were: grades of concrete (normal-, medium- and high-strength), recycled concrete aggregate (RCA) replacement levels (0%, 50% and 100%), rebar diameter (12 mm and 20 mm), splice lengths, ratio of concrete cover to rebar diameter and surface rib characteristics. Similar behavior in bond has been observed in the concrete made with natural aggregates and the concrete obtained by selected levels of RCA replacements which means that the same mechanism was at play in both the types of concrete. A comparison of the obtained experimental results has been carried out by the theoretical models.
