Abstract
Abstract In order to study the flexural behavior of graphene oxide (GO) recycled concrete beams, 6 GO recycled concrete beams were studied, and observe its failure mode and process. The effects of GO content, oxygen content of GO and replacement rate of recycled aggregate on the flexural behavior of the test beams, including cracking load and ultimate load, concrete strain and steel strain, mid-span deflection, were analyzed. The test results show that the cracking load and ultimate load of recycled concrete beams with GO increase to a certain extent with the increase of GO content. And the higher the oxygen content of GO, the higher the ultimate bearing capacity of GO recycled concrete beams. With the increase of replacement rate of recycled aggregate, the cracking load and ultimate load of the test beams decrease.
