Hybrid-fiber-reinforced strain-hardening ultra-high-performance concrete (SH-UHPC) with recycled fine aggregates by Rui-Yang Ma, Zhi-Liang Zhang, Jing-Hao Wei, Feng-Yi Zhuo, Han Zhang, Fan Jiang, Xiao-Hua Ji, Yi-Nong Shen, Ji-Xiang Zhu

“…Results showed that RFA-based SH-UHPC with hybrid fiber reinforcement achieved comparable compressive strength (over 100 MPa), and an impressive enhancement on tensile ductility by 68.3 %. Microstructural analyses via SEM, X-CT and microhardness test revealed that due to the lower intrinsic hardness of RFA more internal cracks were observed RFA-based SH-UHPC, indicating the role of RFA as active flaws in high strength matrix of SH-UHPC resulting in more saturated multiple cracking and enhanced strain-hardening behavior. …”
