Talk:Expansive clay

removed from article
Stray reference (correctly) removed from article, but probably useful:

Damage to Foundations from Expansive Soils, J. David Rogers, Robert Olshansky, and Robert B. Rogers

Two different topics under one heading
This article conflates expansive clay (e.g., smectites) with expanded clay (e.g., aggregates produced by firing shale). I would suggest removing all references to aggregate. (New to this...sorry if I haven't followed proper formatting).
