| 英文摘要 | Concrete demolition waste has been proved to be an excellent source of aggregates for new concrete production. Four types of recycled concrete specimens were made for cyclic loading tests in laboratory, in order to research the acoustics parameters and deformation feature of recycled concrete under cyclic loading. Acoustics parameters such as ultrasonic wave time, ultrasonic velocity and ultrasonic amplitude of recycled concrete were tested synchronously while recycled concrete were loaded. Test results show the evolution of fatigue total strain of recycled concrete undergoes three stages. The cycle times in the three stages accounted for 10%, 80% and 10% of the fatigue life respectively. These stages can be simulated by power function equations, first-order linear equations and exponential functions accordingly. Tests results show that wave time increased with the rise of cyclic times, while wave amplitude decreased in the same time. |
