摘　　要：结合徐州市近期一年的钢筋混凝土工程的检测数据结果,依据相关规范,通过翻阅设计资料、现场检测、实验室模拟检测及数据数学模型分析等方法,研讨不同龄期情况下混凝土强度方法性差异及后续控制把控关键性问题,为类似工程及工程质量控制提供参考。Based on the testing data of the reinforced concrete project in Xuzhou City in the recent year, according to relevant specifications, the methodological differences of concrete strength at different ages and the key issues of subsequent control are discussed by reviewing the design data, on-site testing, laboratory simulation testing and data mathematical model analysis, so as to provide reference for similar projects and project quality control.

关 键 词：混凝土抗压强度 芯样 回弹法 钻芯法
