摘要
结合国内外大量试验结果,文章对再生混凝土的单轴受压性能进行了详细的综述与分析。主要内容包括再生混凝土的抗压强度及其变异特征、棱柱体强度与立方体抗压强度的关系、再生混凝土的应力-应变曲线、峰值应变、极限应变、弹性模量和泊松比。研究结果表明,除极限应变和泊松比外,再生混凝土的其他性能与普通混凝土均存在一定的差异。
An extensive review of the properties of recycled aggregate under uniaxial loading was presented based on the related test results performed in China and other countries,mainly including the compressive strength of recycled aggregate concrete and its variation, the relationship between prism strength and cube compressive strength, the stress-strain curve, peak strain, ultimate strain, modulus of elasticity and Poisson＇s ratio. It was found except the ultimate strain and Poisson＇s ratio, the other above mentioned properties are different from those of normal concrete.
