摘要
采用废砖粗骨料、废混凝土细骨料完全替代天然骨料,配制了5组不同配合比的再生混凝土试块。通过试验得到立方体试块的抗压强度、碳化深度以及棱柱体试块的轴心抗压强度、弹性模量、收缩等力学性能指标。经分析得出轴心抗压强度与立方体抗压强度、弹性模量与抗压强度的关系,并对混凝土碳化和收缩公式进行了拟合。
Preparation of five different mix of recycled brick concrete blocks was done.The compressive strength,carbonation depth,elastic modulus,shrinkage and other mechanical performances were obtained through the tests.The relationships between the axial compressive strength and cube compressive strength,elastic modulus and compressive strength were obtained.Carbonation and shrinkage formulas of concrete were also fitted.
