Abstract

Using the contrast tests of 13 recycled aggregate concrete beams and natural aggregate concrete beams, theeffects of replacement ratio of recycled coarse aggregate and shear -span ratio on the characters of shear capacity anddeformability of recycled concrete beams are investigated. The test result shows the deflection and diagonal crack of recycledaggregate concrete beams are bigger than natural aggregate concrete beams, the shear capacity of recycled concrete beamsreduceswith the increase of recycled coarse aggregate content, the shear capacity reduces with the increase of shear -spanratio. Based onthe result offailure by shear of recycled concrete beams andusing the ultimate equilibrium theory, a formulafor the shear strength of recycled concrete beams is recommended.
