Hi Jackie !
Being old school cement block were called cinder block so i assume a good portion or the block was made from cinders= ash . Also ash is very alkaline like lime so chemically similar too . Best way is to try a small batch a see for yourself u may be pleasantly surprised ! Conrad

Here is another question I have about possibly cutting down on cement powered. I've read that some people add coal ash with the cement powered up to 1/3 without harm. 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???
