DETECTING THE PROGRESS OF INTERNAL CRACKS IN CONCRETE BY CASE OF COHESIVE TERRAIN

SULLA PROGETTAZIONE DEI DIAFRAMMI INCASTRATI ED ANCORATI NEL CASO DI TERRENI DOTATI DI COESIONE

The observed shape of the concrete plug extracted in a pull-out test on a resin grouted block-ended bolt anchorage had previously suggested a theoretical failure model. The hypothesis proposed a two-part fracture mode with the lower, internal failure surface being of primary importance. The experiments described here wee designed to test the proposal by using brittle electrical conductors to monitor the progress of the internal cracking. (a)
