Two tiles. 1hr30min. 3/4 -ish bag quickcrete + portland.
We will need at least 4 people (the more the better!) per final pour, and will also need to complete two pours a day; friday through tuesday at 8-9am and 7-8pm – these times can be adjusted but should remain 12 hours apart. Hopefully this level of production will take care of 1-2 potential failures per pour, and leave us with enough successful tiles to construct our wall.
