Diagnostic properties of concrete exposed to high temperatures
Hudský, Petr ; Sitek,, Libor (referee) ; Bodnárová, Lenka (advisor)
This master’s thesis studies the problems of high temperatures on cement concretes, their following diagnostics from pre-treatment to rehabilitation, the emphasis was on the use of high-speed water jet. In the experimental part of the design of a concrete composition with basalt aggregate. Were reviewed the physico-mechanical properties after thermal loading. The influence of pressure water jet on the thermal load on concrete, pull-off test, the volume of the removed concrete with a strength evaluation and comparison.

Possibilities of rehabilitation of concrete structures damaged by high temperaturesv
Vovesný, Václav ; Sitek,, Libor (referee) ; Bodnárová, Lenka (advisor)
The bachelor thesis studies the behavior of the cement concrete exposed to high temperatures. The theoretical part describes the processes in the concrete structure and its individual components. It also describes the diagnostic possibilities of the concrete and its subsequent rehabilitation. In case of rehabilitation and surface pretreatment possibilities, the emphasis was mainly placed on the high-speed water jet. Physical-mechanical properties of the samples were verified by heavy load of pressure from high-speed water jet and high temperature in the experimental part.
