- Abstract
- At present the design of concrete is usually based on empirical relationships between materials and properties, and experience with its performance. Another approach for selecting concrete is based on predictions of service life. While this approach is not yet often used, it is likely to have an increasingly important role in designing concrete. There are serveral methods for predicting the service lives of construction materials. They include i) estimates based on experience, ii) deductions from performance of similar materials, iii) accelerated testing, iv) applications of reliability and stochastic concepts, and v) mathematical and simulation modeling based on the chemistry and physics of degradation processes. These methods are discussed in this paper, along with examples of their applications.
