| Abstract | The process of selecting candidate structures (and appropriate components of structures) for lithium treatment invariably involves sampling one or several components of the structures for laboratory investigations, particularly petrographic examination, and expansion tests (expansion tests optional). This sampling is done to (1) confirm whether alkali-silica reactivity (ASR) is an important part of the deterioration process, (2) determine the extent of the deterioration and, (3) if required, determine how much more expansion/deterioration is to be expected. Figures 1 and 2 show the types of cracking that can be a visual indication of a candidate for lithium treatment. |
