摘 要:再生混凝土应力-应变本构关系是分析再生混凝土结构承载力及变形破坏的主要依据,本文针对六种不同再生粗骨料替代率、三个龄期的棱柱体共54个试件进行轴心抗压强度试验,分析了不同再生粗骨料替代率对再生混凝土全应力-应变曲线和轴心抗压强度、弹性模量、峰值应变及极限应变的影响规律。结果表明,再生混凝土全应力-应变曲线与普通混凝土相似,弹性模量均低于普通混凝土,峰值应变随着取代率增加而增大,极限应变则随着取代率的增加呈先增后减趋势。
Abstract: Stress-strain constitutive relation of recycled concrete is the main basis for analyzing the bearing capacity and deformation failure of recycled concrete structure. The axial compressive strength tests were carried out on a total of 54 test pieces of prism objects with six different replacement rates of recycled thick aggregate and three ages. The influences of different replacement rates of recycled thick aggregate on stress-strain curve and axial compressive strength, elastic modulus, peak strain and ultimate strain of recycled concrete were analyzed. The results show that the stress-strain curve of recycled concrete is similar to that of ordinary concrete, and its elastic modulus is lower than that of ordinary concrete. The peak strain increases with the increase of replacement rate, while the ultimate strain increases first and then decreases with the increase of replacement rate.
