Scientist in the UK have are delving into the strength of rammed-earth walls. It turns out that moisture content, which in turn leads to cohesion at the molecular level, is a most important characteristic. There is an article about the research here which is written by The Northern Echo, a UK publication. The study abstract can be read directly or the pdf can be purchased at the same link on the website of Géotechnique, a journal for soil scientists.
