Studying the behavior of concrete at high temperatures
Žák, Michal ; Sitek,, Libor (referee) ; Bodnárová, Lenka (advisor)
This bachelor's thesis is focused on behavior of concrete at high temperatures. The theoretical part describes processes, which take place in concrete at thermal loading and further there was described testing of concrete at high temperatures. Next there was described influence of high temperatures on each component of concrete and design of appropriate components for concrete exposed to high temperatures. In experimental part mixes was made with greywacke aggregate, amphibolite aggregate and with the addition of polypropylene fibers. In these mixes was determined the effect of high temperatures on the density of concrete, dynamic modulus of elasticity of concrete and compressive strength of concrete.
