Description	The objective of the present project consists in employing the acoustic emission (AE) to assess the frost resistance of roofing tiles, both concrete and fired. The main task consists in the design of a screening line, which will, based on the measurementof an AE parameter, reject individual tiles on the basis of presumably low frost resistance and, consequently, short service life. Ensembles of roofing tiles, both concrete and fired, coming from three different producers, will be created. The AE parameters will be measured on different tiles before the cyclic temperature stressing and subsequently, after different degradation stages. %22Impact Echo%22 method will be used, i.e., an AE signal, having been induced by a short-time mechanical impulse applied to the specimen surface, for example, by means of Schmidt impact hammer, will be measured. Thus generated acoustical signal will be reflected by defects presumably present in the bulk to propagate back to a surface mounted pick-up. In this way, (en) Cílem projektu je využití akustické emise pro posouzení mrazuvzdornosti střešních krytin, a to jak betonových, tak i pálených. Hlavním úkolem je navržení třídící linky, kde by na základě měření parametru akustické emise došlo k vyřazování jednotlivých kusů krytiny, u nichž by byl předpoklad malé odolnosti proti mrazu a tedy i nízké životnosti. Budou vytvořeny soubory krytin od tří výrobců, a to jak u betonových , tak i pálených tašek. Parametry akustické emise budou měřeny na jednotlivých taškách předzapočetím cyklického namáhání tepelnými změnami a potom po jednotlivých etapách degradace. Konkrétně bude využito metody Impact Echo, to je měření signálu akustické emise vybuzeného rázem vyvolaným na povrchu krytiny krátkodobým impulsem, např. Schmitovým kladívkem. Tento vyvolaný signál se odrazí od defektů a vnějšího povrchu zpět do snímače. To umožňuje zjišťování vad pod povrchem krytiny a umožňuje získat spolehlivou informaci pro detailnější lokalizaci dutin, trhlin, hnízd a jiných vad.
