Abstract
A number of structures worldwide are known to (or will) suffer from chemically induced expansion of the concrete. This includes not only the traditional alkali aggregate reaction (also known as alkali silica reaction) but increasingly delayed ettringite formation (DEF)

Notes
- 1.
It is well known that DEF is often associated with AAR, however it is increasingly observed that it can occur by itself in massive concrete structure subjected to early age high temperature and under high relative humidity (above 95%).
- 2.
The sixth (Salzburg) and the eighth (Wuhan) benchmarks invited participants to analyze Pian Telessio and Poglia dams respectively. There was no submission to the former, and only two for the second.
- 3.
There is no general agreement on the importance of all these parameters, the list is intended to be inclusive of all those perceived by researchers to be worth examining.
- 4.
These parameters should be used in all subsequent test problems.
- 5.
In a finite element analysis, point from which we determine computed values are commonly referred to as “recorders”.
