摘要:
对大量再生混凝土单轴力学性能试验资料进行整理分析，基于统计分析方法，在借鉴普通混凝土力学模型的基础上，对不同取代率下再生混凝土的各种力学性能指标进行统一分析，提出了适用于不同取代率下再生混凝土的立方体抗压强度、轴心抗压强度、轴心抗拉强度、劈裂抗拉强度、弹性模量、轴心受压峰值应变和轴心受拉峰值应变的统一计算公式，建立了再生混凝土单轴受压、受拉的应力应变全曲线表达式，并将公式计算结果与试验结果进行对比。结果表明：计算结果与试验结果吻合较好；提出的再生混凝土单轴力学性能指标统一计算公式精度较高。
Abstract:
Abundant literatures on the uniaxial tests and theoretical analysis of recycled concrete were studied. Based on the method of statistical analysis and the mechanical model of normal concrete, unified analysis of the mechanical performance index of recycled concrete with different substitution rates was conducted. The unified calculation formulae for recycled concrete cubic compressive strength, axial compressive strength, axial tensile strength, split tensile strength, elastic modulus, peak uniaxial compressive and tensile strains, as well as compressive and tensile stressstrain curves were proposed. The calculation results from formulae were contrasted to the test results. The results show that the calculation results agree with test results, and the proposed unified calculation formula for uniaxial mechanical performance index of recycled concrete has high precision.
