Abstract
The cubic compressive and splitting tensile strength of recycled aggregate concrete reinforced with hooked-end steel and macro-polypropylene hybrid fibers (HFRRAC) was investigated through an orthogonal experiment. The results show that the replacement ratio of RCA has little effect on the tension-compression ratio. And the volume percentages of HES fiber are the most significant influencing factor in terms of fibers. The specimens reinforced with fibers fail in a ductile manner and are enhanced in the energy absorption capacity. The proposed prediction models for cubic compressive and splitting tensile strength of HFRRAC are adopted to predict the experimental results and meet the engineering application accurately.
