alt Hacker NewsI always thought of concrete as cement + water + sand.
This video makes aircrete with cement + water + thickening/foaming agent, but it doesnt use any sand, no?

Concrete is cement plus aggregate (it doesn't have to be sand; it could be gravel, for example). Coarse aggregates wouldn't work well in this, but it would be cool for a followup video where sand is used.
The wikipedia pages suggests that this is more prolery referred to as "foam mortar" or "foam cement"

He had a note up that said he's been having some luck with a major addition of sand, but it'll be a bit before the video for that goes up.
Yes, aircrete mixes usually don't contain sand. This isn't something unusual about this video, it's true for most aircrete recipes.
