摘　　要：完成了废弃玻璃细骨料混凝土的单轴受压应力-应变全曲线试验,研究了取代率对再生玻璃细骨料混凝土的应力-应变全曲线形状和抗压强度、峰值应变、弹性模量的影响。研究结果表明,废弃玻璃细骨料混凝土的立方体抗压强度、棱柱体抗压强度、弹性模量随着取代率的不断增加而不断减小,但峰值应变却不断增大;基于试验数据,拟合得到了废弃玻璃细骨料混凝土的应变-应变关系曲线表达式。The complete stress-strain curves of waste glass fine aggregate concrete were tested and investigated.An analysis was made of the influence of varying waste glass fine aggregate contents on the complete stress-strain curve, compressive strength ,peak strain, elastic modulus etc.The test results showed that the cubic compressive strength, axial compressive strength and elastic modulus of waste glass fine aggregate concrete all decreased with the increase of waste glass fine aggregate contents,but the peak strain were higher.Based test data, the function expression of relationship between stress-strain.
