摘要：

In this study, for improving the accuracy of estimating the compressive strength of concrete using the ultrasonic method, a method for measuring the ultrasonic velocity and a method for estimating the strength of concrete were investigated. In an experiment with reinforced concrete members of actual size, the precision of the proposed method for measuring the ultrasonic velocity of inner concrete was confirmed to be high. Furthermore, the estimated value of the compressive strength of concrete in structure using the proposed strength estimation method was close to the actual measurement value.
