Ultrasonic Testing Transformation Model of High Performance Fiber Reinforced Cementitious Composite

According to the homogeneous assumption of a material dispersed medium, a model named as an equivalent sandwich layer model was proposed in this paper for high performance fiber reinforced cementitious composite (HPFRCC). The velocity of ultrasonic waves in HPFRCC was transformed into the equivalent wave velocity value in normal mortar. The ultrasonic testing technique for HPFRCC was then constituted based on modern ultrasonic testing code. From the comparisons of strength between the model predictions and tests, it was shown that the ultrasonic testing method based on the sandwich layer model is feasible for HPFRCC. The model proposed in this paper may be a basis for the establishment of nondestructive testing technology for HPFRCC structures.
