Another day of patient gradual progression.
A bit challenging that the square tube/square pipe filled with crushery and cement got so heavy even for 4 men, probably around 140-160 kg.
Even just leaning against the wall it was bending a lot from the weight of the wet cement and stones inside.
We barely got it up on the roof but it was an effort that we didn't feel 100% in control of and everyone got tired from it, so I think we will probably leave the other square tubes empty for now and just consider buying couple extra to add strength.
That saves us literally a ton of weight on the wall too, if each is around 150 kg and we would do 6-7 of them.
I wish that I had some engineering software right now that I could run some numbers through, but I do know that our blocks are stronger than those from most two story houses around here, so we should be fine.
However, if the square tube bent this much from just the cement and crushery inside it, it means these beams will struggle with a full floor on them, so I will support the beams a lot both while we make the floor and after.
I feel a little bit like I am skating on thin ice honestly.
