Assessment of the strength of concrete structures by a combination of non-destructive and destructive methods
Masařík, Dominik ; Kocáb, Dalibor (referee) ; Cikrle, Petr (advisor)
This bachelor's thesis is about a combination of destructive and non-destructive methods, including a description of the most modern devices of reflection hardness testers. Further on, an analysis of the new norm ČSN EN 13791 is performed. The practical part of the thesis is about measuring on concrete bodies using the latest rebound hardness tester SilverSchmidt, ultrasonic pulse method and tests of compressive strenght of concrete on individual bodies. The evaluation took place on the base of established linear and quadratic regressions on the test specimens. In situ compressive strength was deternibed according to the procedures specified in the ČSN EN 13791 standard.
