On-Site Concrete Segregation Estimation Using Image Analysis

Some tests allow the checking of the fresh concrete properties at the concrete mixing plant, but there is at the present time no method to assess concrete segregation on site. The development of a quick and low disturbance method allowing quantification of the segregation phenomenon auto- matically within structures constitutes an advance in the pathology detection area. The method presented ...

On-Site Concrete Segregation Estimation Using Image Analysis

Segregation remains one of the major problems for traditional and self-compacting concrete. The consequences of this pathology are numerous and may affect the long-term properties of the structures. In order to ensure the expected characteristics of the concrete, it is essential to be able to check its homogeneity. Some tests allow the checking of the fresh concrete properties at the concrete ...
