Abstract: Frost and frost deicing salt resistance of cementitious materials has been the subject of numerous research projects during the past decades. Hence a large number of different frost and frost deicing salt damage mechanisms are proposed. Nevertheless none of them can explain all phenomena observed in experiments or on site. Most damage mod¬els describe certain specific damage situations or special aspects of frost deicing salt damage only. Based on own experimental data, a sequential damage model that tries to involve all major aspects of frost damage is presented here. The model distinguishes between five different phases that are passed when a cementitious material undergoes a frost cycle. Each of these phases is important for a progressive deterioration and is char¬acterized by a dominant mechanism. Laboratory and on site deterioration aspects are discussed.
