Hello CaptO,
This is an extract of the ministry of public instruction and fine arts and it is about a test series of Portland concrete, they tested how long it takes to set up, to dry, the hardness with different amount of concrete, the thermal axpension and so on.

That's interesting - maybe. Perhaps from an engineering standpoint, I suppose.
I wonder why he kept it?
Thanks for the translaton!
