The masers’s thesis is about the methods of non-destructive testing and about determining the properties of prestressed concrete. The first part pursues an introduction on the prestressed concrete, its essence and material properties. The next section describes the non-destructive diagnostic methods used in the practical part – the ultrasound impulse method, the resonance method and the rebound hardness test method. There are described destructive tests on the specimens for the calculation of the calibration. This is followed by a practical part, which describes the item tested - truss, its manufacturing, storage, and perform the test. Then search value are calculated from the test results and results are compared according to various procedures specified in the standards. The last section is devoted to the calculation of camber truss and loss of preload.
