But one thing I don't understand.and sound foolish, maybe my ignorance : Ceament it's a kind of glue to connect sand or sand and small rocks (concrete). How can just the "glue" alone work as a material, resistent ?

The air-entrained,cellular concrete my dad made was an 8-sack,Portland cement,per cubic yard of sand mix.At 11-pounds/cubic foot,it would have no structural strength at all,and would basically be for fire-proofing and sound proofing floors in commercial/apartment buildings.
