Determination of the degradation level in fire-damaged RC constructions

Degradation of material as a consequence of synergistic action occurs at the fire affected reinforced concrete constructions of both physical (temperature shocks, expansion pressures of water steam etc.), and physically chemical mechanisms (decomposition of cement swage, modification changes in aggregate etc.). With regard to these facts it is obvious that correct judgement of state respectively measure of disruption of constructions interfered this way makes demands on measure of tests and analysis realized in the frame of constructional technical research. The article presented treats problems of diagnostic procedures indispensable for valuable judgement of state of fire-affected constructions.
