Updated spreadsheet

Thanks Bruce. All of the credit is yours of course for having made the spreadsheet in the first place.

Attached is a copy the corrects the math typo. If I screwed up anything in the process please point it out. And if you want to update your spreadsheet in the future, I'd be happy to delete this copy.

Cheers

Hello Mullins

I made 2 blocks of Perlite/Cement to go under my entry columns. It was a 5:1 ratio and I was surprised how strong it appeared to be. The edges would crumble but it had good compressive strength.
I went with FB because I did not want to gain too much height under the floor. I did consider using both Perlite/Cement and FB in combination.
