Abstract
This experimental study assesses the bond performance of recycled aggregate concretes (RAC) with embedded uncorroded and corroded steel bars. The RAC were produced using 20%, 50% and 100% of coarse recycled aggregates obtained from the crushing of waste 40 MPa compressive strength concrete. Three degrees of corrosion were reached on the steel bars. The uncorroded RAC specimens presented a comparable bond strength to that of conventional concrete (CC). Low corroded RAC specimens presented better bond performance and later superficial cracking when compared to those of CC. At a higher corrosion degree, all concretes presented a similar bond capacity. The ultimate bond strength estimation models used for CC were adequate for its prediction on RAC.
