Abstract
An objective of service-life methodology is to develop a technical basis for predicting the useful life of concrete. Several methods have been used for predicting the service lives of construction materials. They include a) estimates based on experience, b) deductions from performance of similar matterials, c) accelerated testing, d) mathematical modeling based on the chemistry and physics of degradation processes, and e) applications of reliability and stochastic concepts. These methods are discussed in this paper, along with some examples of their applications.
