[papercreters] Re: screened wood ash added with cement?

Not sure if you were asking me, but they did not use coal ash in the old blocks, they used crushed clinker which is actually a rock / mineral byproduct left when the coal is burned not what we typically think of as ash.

Has anyone ever heard or tried using screened wood ash in the same way?? Does anyone think this could be possible without harming or weakening the papercrete???
