What are the compressive strength & modulus of rupture for the bricks?
What are the nominal compressive strength & modulus of rupture for the bricks as per the international building code(IBC2018)?
You appear to be using 555PSI to create them but were you able to test their strength as individual masonry units? Naturally this will vary depending on the composition of the earth used but do you have any typical numbers? I’m curious about passing inspection.
