Re: [papercreters] Re: Gypsum

I would contact my University County Extension and ask them, or your University Engineering department and ask them.
We pay their wages.
Some Uni have departments of Construction Sci, they may have data on this product.
If it turns out great we will all benefit.

You are thinking along my lines with regard to gypsum sticking to wood. I also learned something about gypsum from reading about its agricultural use. It somehow removes or equalizes(? can't think of the word I want - nullifies?, corrects?) salt in the soil. So maybe it does something to help cure the cement?
Does anyone know what I am talking about here?

I was thinkning of adding gypsm(plaster of paris) to my mix for slipforming. I think it would be great to fill the small place to get to the windows/post/door since it's supposed to stick to wood so well, if the mix is dry, it should minimalize shrinkage a lot... haven't tested it yet though.
