Abstract

Alkali-silica reactivity(ASR) has been recognized as one of the most deleterious phenomena in concrete. In fact, ASR can cause significant loss of mechanical properties and cracking in concrete structures that could lead to structural failure. The challenge now exists in evaluating the degree of the ASR damage in existing structures so that informed decisions can be made toward mitigating ASR progression and damage. Reliable methods and tools are needed in order to evaluate the condition of ASR affected structures. This evaluation includes (a) tests to determine the degree of expansion that has already occurred; (b) the degree of expansion that can be expected; and (c) the rate at which that expansion can take place.
