Some notes on mudbrick strength:

And compressed earth block (CEB):

Basically mudbrick has a compression strength of 1.5+ Megapascals (MPa), and CEB is generally even higher. One atmospheric pressure is 101 325 Pascal; a Megapascal is more-or-less one million Pascal, or 10 times atmospheric pressure. In other words, one MPa is 10 times stronger than it needs to be to resist the force of gravity on earth, stand on its own and not be crushed.
A good mud-brick has a MPa strength of around 1.6 to 1.9 MPa, CEB is 2-3 MPa, while a clay-fired brick has an MPa strength of around 14. Concrete ranges between 15 and 25 MPa.
