Development of mathematical models for prediction of the service life of concrete has reached a state at which use of models should routinely be considered by designers who need to achieve, with the highest degree of reliability, the desired durability or service life of the elements in a concrete structure. (In this document, because of its more quantitative connotation, the phrase “service life” is preferred to the term “durability.”) The purpose of this article is to provide a brief introduction to the types of service-life prediction models for concrete and to indicate how models can be used in almost every phase of the design process to increase the probability of achieving the intended service life for a concrete structure.
