摘要
The paper presents a number of experimental data of high temperature resistant concrete development. Design of special concrete requires an original procedure, because it is not possible to use traditional material sources for concreting. Hydrated Portland cement loses its strength and also chemical changes take place in its mineral composition when it is exposed to high temperature. Resistance to high temperature was observed by mechanical properties changing like compressive strength and three-point bending strength. Presented concrete mixtures were reinforced by various types of fibers to improve fracture properties and aluminous cement was used to provide high temperature resistance. The experimental studies were also conducted to examine the influence of amount of individual components in concrete mixtures to its properties.
