摘要：通过改变石粉（SP）含量（0、5%、10%、15%）和再生粗骨料（RCA）取代率（0、33%、66%、100%）进行了48个棱柱体受压应力-应变全曲线试验，研究了石粉、再生粗骨料对机制砂再生混凝土轴心抗压强度、峰值应变和弹性模量的影响。基于损伤力学原理，参考已有的普通混凝土应力-应变本构关系，建立了机制砂再生混凝土单轴受压应力-应变本构方程。结果表明：理论曲线与试验数据吻合度较好。 Abstract: 48 prismatic specimens with full manufactured sand and different levels of recycled coarse aggregate (RCA) were prepared to test the compressive stress-strain curves. The effect of limestone powder (SP) in manufactured sand (0, 5%,10%, 15%) and RCA(0, 33%, 66%, 100%) on axial compressive strength, peak strain and elastic modulus of the concrete was studied. Based on the damage mechanics theory and the compressive constitutive relation of commom concrete, the stress-strain equation of concrete with recycled coarse aggregate and manufactured sand was established. The results show that the theoretical curves have high coincidence degree with the experimental data.
