Among Non-destructive tests Ultrasonic Pulse Velocity Method is identified as an efficient and simple method to estimate the mechanical characteristics of the material. In this study, Ultrasonic Pulse Velocity Method for Normal concrete were applied to geopolymer concrete specimens. Pressure waves, ultrasonic velocity and maximum frequency in these specimens were measured. similar to normal concrete, Initial ultrasonic velocity of geopolymer concretes reflected stress of geopolymer concretes, but maximum frequency bandwidth did not.
