The research presented in this paper deals with concrete containing building waste recycled as aggregates. The frost resistance is used as a durability indicator. The characteristics of recycled aggregates (RAs) and their impact on the characteristics of RA concrete are presented. Some basic factors concerning the frost resistance of RA concrete as RA content and degree of water saturation are considered. The RA concrete is compared with a control concrete made with natural aggregates. The pertinence of different criteria for the assessment of the frost resistance is also discussed.
