RE: [papercreters] Re: Gypsum

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.
