Hi Rambler, thank you for the comment on not seeing those items in the block.

Here is a direct copy n paste from www.tnttt.com

In the US that stuff is called AAC (autoclaved aerated concrete). To us northeners, it is unobtanium. You can work it with wood working tools and it is a lot lighter than regular concrete. It has insulating properties too. When I lived in Germany I helped a sister in law renovate the bathroom in a french farmhouse using this stuff. We carved the block to make the base for a new bathtub and put in lots of insulation. Have to say that it was a total transformation.

Anyway, here is a link to where one can get this stuff in the USA (if you live close enough) http://www.aerconaac.com/

I would love to build a new house with it, but I'm sure transport cost would be outrageous...
