DRP houses sophisticated facilities for optical and electron microscopy. This is an EDS phase map of a concrete sea wall subjected to marine water attack and alkali-silica reaction.
Petrography is a fundamental aspect of investigating deterioration from durability mechanisms such as alkali-silica reaction.
Pictures really are worth thousands of words. The scanning electron microscope reveals secondary deposits in striking detail.
Raw materials are crucial. Fly ash under the electron beam...
Maybe the problem is with something besides the materials. An example of happy concrete...
The most important aspect of petrography is understanding how it relates to the performance of the larger structure.
