Abstract:In order to study the shear resistance of brick-rich recycled concrete, four groups with different proportions of brick-rich recycled concrete specimens were prepared.Taking 28d cube compressive strength value as variable, the influence of cube compressive strength on shear stress-strain curve was studied based on the analysis of the effect of cubical compressive strength on shear strength. The results show that the shear failure mode of recycled brick-reinforced concrete is similar to that of ordinary concrete.With the increase of compressive strength, the shear strength of recycled brick-rich recycled concrete shows an obvious increasing trend.Based on the test results, the constitutive equation of shear stress-strain was established and the formula for calculating the shear modulus of brick-rich recycled concrete was proposed.
