[Cob] roman cement

[Joe Skeesick]

I doubt that wood ash would work as a viable substitute (though I can't say
definitively that it wouldn't) However, here in the UK (as well as other
non-volcanic Roman territories I'm sure) they substituted brick dust/fired
clay for volcanic ash.

i have been a lurker for some time now and have found the list to be
informative,helpful,and at times entertaining(wont mention the who) i would
like to ask if hardwood ash (almost exclusively red oak) could be used
inplace of volcanic ash to make a mortar. cobbing in pa  chris
