| Abstract: | Different cement ratio of cement soil are tested with ultrasonic instrument in 120 days of(curing).The ultrasonic wave signals were analyzed by FFT,and the frequency spectrum characters of(ultrasonic) wave were obtained.The quality and strength of cement soil can be judged by its frequency spectrum character,ultrasonic wave form and velocity,and the range of best cement content is(established). |
