    Wpływ wieku próbek zaprawy cementowej na ich właściwości pozniszczeniowe
    (Wydawnictwa AGH, 2009) Szumiński, Andrzej; Klisowski, Robert
    As indicated by the results of most laboratory tests concerning the post-failure behaviour of concrete, the nature of the material failure corresponds to class I after Wawersik, which points to stable failure propagation. The results presented hereby ensue a research conducted to verify the thesis, that in cement binder based materials (concretes, mortars) the degree of cement grout hydration, advancing along with material age, may cause the change from class I to class II post-failure behaviour. This means, having exceeded the compression strength, the accumulated energy will be released in ruptures.
