再生砖粗骨料混凝土单轴受压力学性能研究

摘要

The mechanical behavior of recycled brick coarse aggregate concrete under uniaxial loading were tested and investigated.An studies was made of the influence of varying recycled brick coarse aggregate contents on the cubic compressive strength ,axial compressive strength and elastic modulus.It was found that the cubic compressive strength,axial compressive strength and elastic modulus of recycled brick coarse aggregate concrete all decrease with the increase of the recycled brick coarse aggregate contents,but the peak strain were higher.Based test data,the function expression of relationship between stress-strain.%完成了再生砖粗骨料混凝土的单轴受压力学性能试验，研究了不同取代率对再生砖粗骨料混凝土的立方体抗压强度、棱柱体抗压强度、弹性模量的影响。研究结果表明：再生砖粗骨料混凝土的立方体抗压强度、棱柱体抗压强度、弹性模量随着取代率的不断增加而不断减小，但峰值应变却不断增大；基于试验数据，拟合得到了再生砖粗骨料混凝土的应变-应变关系曲线表达式。
