| 摘 要： | 对再生混凝土与普通混凝土的单轴受压性能进行了对比试验研究,主要包括弹性模量、应力应变曲线上升段以及峰值应变.研究结果表明,再生混凝土的弹性模量比普通混凝土低,用普通混凝土弹性模量计算公式不再适用于再生混凝土,在对试验数据进行了回归分析的基础上,提出了再生混凝土弹性模量的计算公式.应力应变曲线的上升段与普通混凝土相似,都是用3次多项式拟合,其峰值应变比普通混凝土高.

| Abstract: | An experimental research on behavior under uniaxial compression between recycled aggregate concrete and normal concrete,tests were conducted to modulus of elasticity,rise stress-strain curve and peak stress.It was found that the modulus of recycled aggregate is lower than normal concrete,and the equation for normal concrete overestimates the modulus of elasticity for recycled aggregate concrete.Based on the data regression analysis,the modulus of elasticity formula of recycled aggregate concrete is obtained... |
