We also did some formulas using portland cement and lime, and one using lime with magnesium phosphate. I'm hoping this will give us a good idea of where we can stand with strength/insulation relationship and tweak the formulas accordingly. We tried to keep the cement levels to 20 to 25 percent to maintain high strength.
