the Best Aircrete Recipe

Formula for making the best aircrete. I slowly add the portland cement to the water while spinning the slurry with a paint mixing attachment on a drill. I want a smooth, well blended slurry here with no clumps or dry cement on the bottom or sides of the pail. Adding portland cement to pail. I'll add the glass fibre and mix that in.

what are the correct CONCRETE MIXING RATIOS

To make concrete there are four basic materials you need: 1. Portland cement - You can buy this in a 94lb bag 2. Sand - Course or Fine will work (course sand will give you a stronger mix) 3. Aggregate (stone) You can use 3/8", 1/2", or 1/5" stone for aggregate 4. Water - Clean cool water is best.

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.
