I saw this product used on the UK show "Grand Designs". It's concrete injected with air so that it has a much lower weight, is more fire resistant and has much higher insulation values.
This company in Canada makes it in block form so that you could DIY but there are probably other manufacturers in the US too.

Don't know how they can call it more fire resistant.

Used in northern Europe a lot. It is porous so needs to be covered with something to keep water out. Stucco is used on the exterior a lot in EU. It is made in a factory so transportation costs have to be factored in. EU is more compact than the US. The mortar to hold the segments together needs more precision application. Not a DIY type of material IMO.

LITEBUILT® concrete is extremely fire resistant and well suited to fire rated applications. The application of intense heat does not cause the concrete to spall or explode as does normal dense weight concrete
- Our patented LITEBLOKâ„¢ has a unique interlocking design
- LITEBLOKâ„¢ is dry stacked and does not require mortar joints between the block
8. Finishing
8.1 A variety of different finishes can be applied to the exterior of LITEBLOK structures. Common examples include siding, decorative wall panels, parge coats and stucco.
8.2 In most instances the interior of LITEBLOK structures are lined with stud walls or strapped and dry walled.
I would expect for below ground basement walls you would waterproof it just like any other concrete block wall.
