Study On Shear Bearing Capacity Of Waste Glass-Reinforced Concrete Beams

This test first conducted waste glass reinforced concrete charpy specimen design and installation.Subsequently conducting waste glass concrete beams shear experimental studies at different shear span ratio,the research process is mainly theoretical analysis for the shear stress mechanism and rational discussed the failure modes.Second analysis and discuss the oblique section of each of destruction focus point.At last calculate to derive the waste glass concrete beam shear capacity by analyzing the specification of countries applicability and fitting analysis of the oblique section maximum crack width formula.The test results achieved are as follows:(1) Through experimental research, we found that waste glass concrete and ordinary concrete have similar mechanical properties, but replace part of waste glass aggregate concrete cube compressive strength of ordinary concrete lower than the same condition.(2) Shear Capacity of waste glass coarse aggregate reinforced concrete beams than ordinary concrete beam and waste glass fine aggregate reinforced concrete beams.(3) Analysis of the waste glass concrete beam deflection, drawn baroclinic damage deflection under variation of waste glass of fine aggregate concrete beams, glass fine aggregate concrete beams with ordinary concrete beam shear compression failure under load- deflection curves, oblique damage deflection curve under cullet fine aggregate concrete beams and glass waste coarse aggregate concrete beams.(4) Discussion cullet concrete beam shear capacity formula by analyzing and comparing that value equation specification error six ordinary concrete beam and waste glass of fine aggregate concrete beams closer to its shear capacity approaching the same, but waste glass thick bone calculate aggregate concrete beams and measured values to is not clear, large deviations.
