Monitoring of the fracture mechanisms induced by pull-out and compression in concrete Vrije Universiteit Brussel
In-situ characterization of strength is of paramount importance for concrete engineers. To get an estimation of the compressive strength, slightly destructive tests are conducted on the surface of the material. One is the LOK test (pull-out) which offers a reliable estimation of compressive strength. The developed stress field is quite complicated and researchers have argued about the nature of the fracture mechanism. In the present paper, ...
