摘　　要：目前回弹法检测混凝土强度时,将混凝土表面碳化深度当做强度推定的重要影响因素,以期提高检测精度。但是检测工程实践证明,检测推定现代泵送混凝土强度时,传统的碳化深度修正并不能提高检测精度,甚至降低了回弹法检测精度。The carbonation depth is regarded as an important factor in strength estimation when rebound method is used to detect concrete strength,so as to improve the detection accuracy. However,the actualengineering practice has proved that the traditional carbonization depth correction can’t improve the detection accuracy,or even reduce the detection accuracy of rebound method when testing and estimating the strength of modern pumping concrete.

关 键 词：混凝土强度检测 回弹法 碳化深度
