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.
