It's good to see you on here, Garret. I have been a big fan of your resources for a long time.
I built a ferrocement house for $2/sf, btw.
This might be considered hijacking, but I'm wondering if you have done any more experiments with acrylic concretes? I did a roof a few years back, and I think I've optimized it a bit to do it better. I hope to do another roof later this year to test out the new system. When I was researching it, your resources were a great inspiration to me.
