Methodology of historical bricks and masonry tests
Bartoň, Vojtěch ; Anton, Ondřej (referee) ; Cikrle, Petr (advisor)
This diploma thesis is focused on methodology for sorting of solid fired bricks for reconstruction of historical buildings. The theorethical part of this thesis includes description of production technology of solid fired bricks and diagnostic methods. In practical part there are these methods aplied on the solid fired bricks, which are intended for reconstruction of the bridge in Sedlec. There are monitored changes in structure of solid fired bricks caused by repeated freezing and defrosting. This changes are monitored by resonant frequency method and ultasonic pulse method.

Verification of the usability ultrasonic pulse method for the assessing of frost resistance of concrete bricks
Kašparová, Jana ; Hubáček, Adam (referee) ; Brožovský, Jiří (advisor)
Purpose of Bachelor thesis is to verify use of the utrasonic impulsive method to determine frost resistence of the concrete. Theoretical part disscusses about basic characteristic of a vibropressed concrete, description of a causes of frost and defrosting on the concrete. As well further factor simple menting frost resistance are reviewed. Summary is followed with standard requirements forwall concrete elements, trial proceduresfor non destructive and destructive methods for concrete and other construction materials and thein evaluation systems. Second part of Bachelor thesis is dedicated to analyse and evaluate results and relationship of trials used for testing of a concrete brick in frost resistence with use of cyclic freezing and use of a trial non destrucive ultrasonic impulsive method as well destructive mode.
