Non-Destructive Analysis of Concrete from Northwest Bohemia Defence Structure built in 1937
Original language description
This contribution deals with the experimental investigation of compressive strength of over 80 years old reinforced concrete structure. In various regions of the Czech Republic we still have a large system of defence structures built in 1930th as the reaction for political development in Germany and the potential risk of war conflict. In this contribution the results of non-destructive analysis of concrete used in one defence structure in northwest Bohemia region are presented. The compressive strength measured in 1937 achieved 41.5 MPa. The non-destructive analysis was performed mainly in the interior part – roof and walls and also in one location in the exterior. The compressive strength measured by Schmidt hammer achieved 68.5 MPa in the exterior part, 53.2 MPa for roof in the interior part and the wall in interior achieved between 49.4 MPa and 58.5 MPa. Performed non-destructive testing provides the approximately information about the quality of concrete without damaging the historical structure.
