Light weight aircrete ...

salah1

Hi guys:
This is my first post I hope I will get some reaction. I plan to make some light weight concrete using water solution (made by water and some detergent).
What should be the air pressure to get dense stable foam with 90-100 gram/litre density??
Some articals and videos says it should be about 90psi ,others like Harry aircrete gives 15psi ...
Thank you.

Are you trying to reduce the weight of the mix? Or just reduce the conductivity?

They can add an air entrainment at the redimix plant, or you could add it to a home batch
