If one enters Googel Aircrete one finds on German sides first references to aerated concrete (which is not the same) or to an elaborately manufactured product with plastic balls. This is surprising, because it has probably been known in the English-speaking world for some time (see first movie).
Aircrete consists mainly of air (scavenger-based scum) and a relatively small amount of cement mixed together. It is extremely light, durable, fireproof and has both load-bearing and insulating properties. It can be processed like building foam for insulation, but prefabricated parts are also made with formwork and walls and even roofs made of it .
