The paper presents the results of investigations into the failure of four self-compacting concretes under compression. When tested, the concretes were damp to different degrees. The failure processes were investigated by acoustic methods. The levels of cracking initiating stress [...] and critical stress [...], delimiting the stages in the failure process, were determined. Dependence between the moisture content in concrete and the levels of the above stresses has been established. The experimental results were used to calculate the fatigue strength of the tested self-compacting concretes and on this basis the suitability of the latter for erecting structures subject to repeated dynamic loads was assessed.

W pracy przedstawiono wyniki badań procesu niszczenia czterech ściskanych betonów samozagęszczonych znajdujących się w chwili badania w różnym stopniu zawilgocenia. Proces niszczenia betonów zbadano metodami akustycznymi. Określono rozgraniczające ten proces wartości poziomów naprężeń inicjujących pękanie [...] i krytycznych [...]. Wykazano istnienie zależności między wilgotnością betonu, a wartościami tych poziomów. Wykorzystując uzyskane rezultaty badań obliczono wytrzymałość zmęczeniową badanych betonów samozagęszczonych i na tej podstawie sformułowano wniosek odnośnie do przydatności tych betonów do wznoszenia konstrukcji poddanych obciążeniom wielokrotnie zmiennym.
