| Abstract: | The ultrasonic-rebound test and pressure test for the rubble concrete specimens that are prepared with the common materials of the Tianjin area were performed.Based on the results of the tests,the ultrasonic-rebound-strength local curve for rubble concrete in the Tianjin area is established on the regression with four different function models.The results of the error analysis and the curve validity checking show that the local curve can satisfy the needs of the regulations concerned,and that the local curv... |
