该文通过对76组实测数据的统计、分析,得到了回弹法测定混凝土强度与钻芯法测定的强度之间的相关关系,并借以修正回弹法测定值。为检测旧结构混凝土强度提供了一个可行、有效的办法。
Based on the statistics and analysis of 76 groups of measured data, the correlation between the strength of concrete measured by the rebound method and the strength measured by the core-drilling method was obtained and the value of rebound method was corrected. It provides a feasible and effective method for testing the strength of old structural concrete.
