Crumbled sheetrock will mix in a tow mixer. It doesn't add strength but does add mineral content. The gypsum in the sheetrock is hydrated so there is no chemical reaction. If you put the gypsum in a kiln and drove the water off then it would react with the cement in pc, though I'm not sure the reaction would be beneficial or worth the energy.
If you have a pile of sheetrock lying around then throwing it into the mix won't do any harm, and the gypsum filler means that much less pc to mix.

Does sheet rock mix well enough in a tow mixer, and does it add anything to the pc mix? I am remodeling and plan to build a mixer in the spring. Mike in south Texas
