摘要：
This study investigates the effect of using recycled concrete aggregates (RCA) from construction and demolition (C&D) waste combined with basalt macro-fibers (BMF) on the flexural behavior and ultimate capacity of reinforced concrete (RC) beams experimentally and analytically. A total of 16 RC beam specimens were flexural tested to failure. The investigated parameters include the RCA replacement ratio and the volume fraction of the BMF. Furthermore, the experimental results were also compared against the existing analytical models and code-based equations for conventional concrete. The test results show that the flexural capacity of beams with the addition of BMF was improved. On the other hand, the use of RCA has no remarkable impact on the flexural strength of the tested beams. (C) 2018 Elsevier Ltd. All rights reserved.
