| Abstract | ||
| In this work the concrete free falling effect on segregation was investigated. Sixteen free falling specimens were tested by the non-destructive ultrasonic test for four types of concrete. In addition, twelve cube specimens were tested to check the accuracy of the ultrasonic test adopted in this study. Four types of aggregates (rounded gravel, crushed gravel, 10mm maximum size crushed gravel and porcelain aggregate) were used to study their effect on segregation of free falling concrete from different height. The test results show that no significant effect for the free falling on the compressive strength of concrete for the four types of aggregate and the results of the non-destructive ultrasonic test were of good agreement with those of compression machine test. | ||
