| 摘 要： | 采用再生骨料配制再生骨料混凝土(RAC),研究其力学性能,特别是单轴受压应力-应变性能.通过改变再生骨料的取代量,研究再生骨料对RAC力学性能的影响.研究结果表明:随着再生骨料取代率的增加,RAC的强度会略有降低;RAC的单轴受压应力-应变曲线与普通混凝土相近,随着再生骨料取代量的增加,RAC的延展性得到提高;采用数值计算模型和损伤模型构造RAC的本构关系,回归曲线与实测单轴受压应力-应变曲线的吻合较好,特别是数值模型,基本上能够真实地再现应力-应变曲线,可用于混凝土结构的计算分析.

| Abstract: | In this testing research,we prepared a series of recycled aggregate concrete(RAC) with recycled aggregate and studied their mechanical properties,especially uniaxial compressive stress-strain properties.The influence of the recycled aggregate on the mechanical properties of RAC was studied by changing replacement ratio of recycled aggregate.Testing results show that the strength of RAC decreases a little with the increase of the content of recycled aggregate;the uniaxial compressive stress-strain curve of R... |
