@Martin10 if my calculations are accurate then you should need about 2800 blocks. This is assuming a consistent block size as your estimate for a 16 foot diameter dome. I simply took the square footage of a sphere of that diameter and divided that to get a per block ratio (.867 blocks per sq ft of sphere surface area calculated at some diameter) and scaled it. Assuming that you have The same fraction of the dome above the ground as in a 16 foot diameter dome that should be a rather accurate prediction. I could model it on CAD very quickly if you want to get a more accurate number. The fact that it is nearly 4 times the quantity also gives me confidence because the surface area quadruples as the diameter doubles...

I am a custom ICF home builder of ten years turned Mechanical Engineering graduate. I plan to attend graduate studies soon but plan on making a side business of aircrete technologies. I specialize in all aspects of home construction, radiant heat systems, composite engineering, and general problem solving. I am also building an eggshaped teardrop trailer soon that will be a good test for many of my ideas I wish to pursue in aircrete. Please contact me if you are in need of design ideas or help with construction in any way. I would love to travel and help others build their dreams. Have a great day!
