Abstract

Abstract

To study the flexural behavior of waste fiber recycled concrete beams, the static loading test of beams were carried out with the replacement rate of recycled aggregates for 0, 50%, 100%, and the volume of waste fiber blending with 0, 0.08%, 0.12%, and 0.16%. At the same time, a calculation model of reinforced concrete beams was set up based on the finite element software ABAQUS, compared with the test results. The results showed that with the increase of the replacement rate of recycled aggregates, the ultimate bearing capacity of concrete beams decreased. At the meso-level, the waste fiber was the bridge function of fibers, which limited the development of cracks in cement matrix. At the macro level, it improved the flexural behavior of recycled concrete beams. Furthermore, when the replacement rate of recycled aggregates was 50% and the fiber content was 0.12%, the ultimate bearing capacity of waste fiber recycled concrete beams was increased by 0.4%, the calculated values of the finite element model were relatively consistent with the experimental values.
