As a civil engineer, I must say that wasn't a concrete specimen. It was missing gravel ...and gravel is the key to compression resistance .... + concrete needs 28 days to reach its expected results. As far as I could see what has been tested was a mortar sample. - Not saying that it would make that much of a difference in terms of general results.
You called it very late on the ice/paper one. It started cracking long before. But the point about the weakness of unreinforced concrete is well made. In tension it is very poor stuff, and a press produces shear stresses with a tensile componont hoizontally.
I don't think that the concrete had enough time to cure. Cool test though, I'm in awe at how different substances in ice have that much of an effect on the strength.
I disagree EVERY, SINGLE, TIME, in EVERY, FREAKING, VIDEO, about how many kilograms each object resisted. You are not coherent even with yourself. What were you waiting for with the ice+paper? You wanted that one to win so you waited until it was completely destroyed to note the number.
It is a blurry end, it is nothing sure in there. Is not like it is breaking and you can notice of what is the limit. It is slowly putting more and more pressure and not breaking
Btw the number is the limit of the maximus pressure (X) that the object can resist before giving less resistance that the X number. Right after 12k kilograms, we know that it is the limit because it went to 11k right after.
Ele sempre faz isso. Em vez de medir o esforço feito pela prensa até o momento em que o objeto se rompe, ele contabiliza o peso durante todo o tempo em que a prensa vai aumentando o peso, e só para quando o esforço feito começa a diminuir, quando o objeto já se rompeu há muito tempo. Ridículo!

Using gin and vermouth instead of mortar would make a significant difference.
Working in foundation repair, you're 100% right.
The British Navy looked into sawdust ice boats in World War 2. They called it Pykrete.

agreed
Mix concrete and metal shavings, this should create something very strong.
I was very surprised that ice with paper is the strongest.
I'm pretty sure they build fancy car bodies from fibreglass.
I don't think you gave the concrete enough time to cure
That *_"concrete"_* was more like clay.....
It seemed to have chosen the weakest concrete possible.
Incroyable
Bro handling fibreglass like its nothing😂😂😂
ice and cotton
“Concrete” missing aggregate and sand!

Just to be fair,.. I wouldn't exactly call that sawdust, more like wood shavings...
Lol, ice started to crack at around 437 not 1437, what the heck is with this test?:)

Ice and condoms
