Yea, we used Fired Clay (Grog) from a clay supplier here in Wisconsin and it seemed to work great,,,,,,Volcanic Ash is only available in certain areas but plenty of folks have built Roman cement without it -- - - heard burnt clay is a common additive from everything I've read. Woood ash, I don't believe, has the parts that are neccessary for the Lime to react with it, if it does it might be a weak pozzolan.
