| Abstract: | Through ultrasonic-rebound combined method,the velocity of sound wave,rebound data and carbonization depth in component were gained,with the method of multivariate regression analysis,establishing the regional curve for local needs,the relatively accurate equivalent data of concrete strength is gained,the actual problem that met in building project is solved. |
| Keywords: | concrete ultrasonic rebound data carbonization depth velocity of sound wave concrete strength equivalent fata curve |
