摘要:
为研究废玻璃粉混凝土单轴受压作用下的全过程受力特征,对C30与C50两类强度等级,0%、10%、15%、20%、25%、30%六种取代率下的棱柱体试件进行单轴受压应力-应变全曲线试验.通过试验分析了应力-应变全过程曲线变化趋势,对比研究了比例极限、峰值应力、延性系数等性能指标,并采用分段式本构关系对废玻璃粉混凝土应力-应变全曲线进行了研究.结果表明:废玻璃粉混凝土应力-应变全曲线形状与普通混凝土相似,随着取代率的增加,上升段斜率逐渐变小,下降段则趋于平缓,各类取代率下均值曲线的标准差先增大后减小,直至保持不变;与普通混凝土相比,废玻璃粉混凝土的比例极限相对较小,峰值应变则较大,延性较好的原因在于上升段表现出的塑性变形较强;分段式本构方程计算所得曲线与试验所测曲线吻合良好,C30强度等级下上升段参数为2.146,下降段参数为0.8,C50强度等级下上升段参数为1.987,下降段参数为1.462.
Abstract:
To study the whole process mechanical characteristics of waste glass powder concrete under uniaxial compression, the stress-strain full curve tests of prismatic specimens with six substitution rates of 0%, 10%, 15%, 20%, 25%, 30% and two strength grades of C30 and C50 were carried out under uniaxial compression. The trend of the stress-strain curve during the whole process was analyzed and the performance indexes such as the proportional limit, the peak stress and the ductility coefficient were studied. The stress-strain full curve of waste glass powder concrete was studied by using the segmental constitutive relation.The results show that the stress-strain full curve shape of waste glass powder concrete is similar to that of ordinary concrete. With the increase of the replacement rate, the slope of the ascending section decreases, while the descending section becomes more gradual. The standard deviation of the mean curve at various substitution rates first increases and then decreases until it remains unchanged. Compared with ordinary concrete, the proportion limit of waste glass powder concrete is relatively smaller while the peak strain is bigger. The good ductility is due to the strong plastic deformation in the ascending section. The calculated curve of the segmented constitutive equation agrees well with the test curve. For the C30 strength grade, the ascending segment parameter is 2.146, and the descending section parameter is 0.8. For the C50 strength grade, the ascending segment parameter is 1.987 and the descending section parameter is 1.462.
