“…The results obtained by Breccolotti and Materazzi, Kim and Yun and Guerra et al are consistent with the above results where no significant effect of recycled aggregates on the bond characteristics of concrete is found. It should be noticed that all these studies were conducted by replacing one type of aggregates which is mainly the coarse aggregates.…”

The paper presents the results of an experimental program carried out on 96 concrete pullout specimens prepared with natural and recycled aggregates using 10 and 12 mm diameter deformed steel bars. Steel rebars were concentrically embedded in pullout specimens with two embedded length of 5 and 10 times the rebar diameter. The present work includes 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. For both series, specimens were fabricated with different incorporation ratios of fine and coarse recycled aggregates and only coarse recycled aggregates. Tensile load was applied gradually until the pullout failure occurred and the slip between the rebar and concrete was measured at the free and loaded ends for each loading level. Furthermore, systematic observations of failure surface have been made at both macroscopic and microscopic scales. Test results showed that for the same class of compressive strength the bond strength and related failure mechanisms remain very close and the obtained values are, at least, four times higher than the predicted values by Eurocode 2. The experimental results of this study, together with an extensive number of results reported in the literature, were used to describe the variation of bond strength with concrete compressive strength, embedded length, and concrete cover. In addition, an analytical bond‐slip relationship is proposed and the parameters of bond‐slip law were calibrated by an optimization algorithm.

“…Corinaldesi and Moriconi [14], Kim et al [19], Ajdukiewicz and Kliszczewicz [20], Breccolotti and Materazzi [30], Prince and Singh [31,32] have used pullout test method for investigation bond between reinforcement and concrete. The recycled coarse aggregate used by them were used without any treatment such acid, mechanical, thermal, etc., However the aggregates were soaked in water for a period of 24 h and used at saturated surface dry condition.…”

“…However, only in the 70 decade, the studies on RR-C bond characteristics were oriented aiming the obtainment of relations between the mechanical properties of the concrete and the cement. Now, the bond RR-C has been performed in terms of numerical modeling and the zone characteristics implemented aiming a most real model about the behavior of rebar-concrete surrounding zone [4][5][6].…”

The present work provides a special contribution for assessment of the compressive strength of the concrete through a low-cost test. Here, an alternative pull out test is presented and an experimental campaign was carried out aiming the demonstrate the applicability of this novel methodology. Three different classes of concrete were performed, namely C20 (20 MPa), C25 (25 MPa) and C40 (40 MPa), each one with two variations of the reinforcement rebar diameter, that were 10 and 16 mm. In addition, references samples also were casted and submitted to compressive strength test by NBR 5739. The results found confirmed the applicability of the novel methodology for obtainment compressive strength of concrete.
