Paper Title:
Ultrasonic Propagation Characteristics and Damage Evolution of Recycled Concrete under Dynamic Loading
  Abstract

Four types of recycled concrete specimens were made for dynamic loading tests in laboratory, in order to research the ultrasonic propagation characteristics and damage evolution of recycled concrete under dynamic loading. Ultrasonic propagation parameters such as ultrasonic propagation wave time, ultrasonic velocity and ultrasonic amplitude of recycled concrete were tested synchronously while recycled concrete were loaded. Tests results show that ultrasonic propagation wave time increased with the rise of cyclic times, while ultrasonic amplitude decreased in the same time. Damage variable evolution of recycled concrete lived through obvious three stages during the loading process. The development of inner cracks of recycled concrete in loading process accordingly were the stage of the growing of original cracks, the stage of the expansion of cracks and the stage of the linkage of cracks.
