The objective of this work is to review, according to the available literature, some of the conceptual service life models for reinforced concrete in terms of durability, highlighting their contributions and the aspects in which they evolved with respect to their predecessors. The journey is made chronologically to the present time, beginning with the pioneering work of Tuutti in 1982. The transition from phenomenological to temporal models is addressed, as well as from the prescriptive to the performance point of view, and from the general vision to the specialized vision. One of the main conclusions is that each model must adjust its validity to an age range through which the structure transits, warning about the certainty of the predictions depending on the stage of service life to which it is confined. The review ends with reflections on the present and future use of these conceptual models.
