• 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.
