How Strong Is Concrete? Hydraulic Press Test!

welcome to the hyic Press Channel today we have real science video we are going to test how strong is concrete and we have these five different types of concrete here and thanks to VAP and rudus for providing the test samples these are from their local concrete factories test laboratory so these are the same test samples as they use to make sure that their product is up to the standards and we have five five concrete samples we have weak as floor concrete and then couple on the between and then we have high strength concrete that is made to be used on bridge here in Finland and it has to be also able to withstand the cold and salt from the like Road road salt salt this is pretty straightforward and I can calculate how strong this should be but I'm not going to to spoil it before the test I'm going to tell it on the end of the video okay this is the first one regular basic floor concrete and it doesn't have any extra flavoring into it so let's see how strong it is I can say that we surely can crush it but I'm not going to tell more and I'm going to go quite slowly so we can read the reading oh my God it's much stronger than I thought [Music] yeah I was pit worried that it's going to be a shitload of dust but it hardly made any dust it was like much more explosive than I thought I I thought it's going to like slowly crumble yeah me too but that was quite violent yeah let's see did we got the high speed we had some problem with the triggering cable oh we got it yes come have a look and this is monochrome camera because this doesn't need so much life and it's it's running 5,000 frames per second concrete is also not that colorful so might might use the monochrome camera here when it's check the eyes okay here it goes a yeah this is super nice yeah it's like one side yeah but this is the this is the uh same they always fa like this this the same uh failure method as on the window killer brass cylinder [Music] oh down it goes yeah the eyes are the eyes are the thing it's so nice bom okay let's check what is the next concrete concrete type that we have then the next one this the same regular floor concrete but this has microfibers in it so they are bit like the steel things on the concrete just much smaller so they're going to make this stronger but how much stronger that's the question okay here we go again 73 on to [Music] Beed [Music] what look at it hot hey hey you can see the fibers you can see the fibers and they clearly work because it's like cracked but it still stays together yeah I think I'm going to save it like that it's so funny looking I don't want to destroy it because now it's really weak but it looks so funny yeah but it was it looks also tougher guy than the last one the last one funny guy but this is the tough guy yeah yeah but hey viers they're good for you eat your veggies okay and then the next one my note says that this is house building concrete so if you are going to build a house you are going to build it from this and this is also probably the same that we going to use on our future press bunker so this is the probably last video with the safety box 5 million we are going to build press bunker 10 million it's so goddamn good that it's straight straight to 10 million No 5 million needed yeah it also has the wife window 5 million yeah it's it's like perfect in every way but we're going to make video be the pr Channel about the bunker very soon but here we go with the house building concrete this doesn't have any fibers this should be slightly harder uhoh oh my God the whole press stopped that was much stronger how much was it can we even crush the next on yeah we can that was like almost 20 tons more than the floor concrete next ones are bridge concrete those are even harder but uh yeah complete Mayhem in the Box okay here it goes oh Mr Nice Guy going down looks almost like some building building collapsing oh oh the GoPro goes yeah boom yeah I I'm going to say that the next one is going to be interesting because they're even harder okay now we are going to probably go over 100 tons because this is much stronger this is concrete meant for Bridges and this can take the freezing cold and also the salt that they spread around here during the winter to keep the roads not super sliber so so let's see how it goes and then we have one after this that is going to be even stronger oh my God that's [Music] strong cool that was really strong the table jumped out from its place yeah check this not optimal not optimal yeah we have to we have to drop that in backage place yeah but that was a that was a loud loud explosion let's see the high speed yeah this was first one to lose its face yeah just explodes yeah oh oh [Laughter] no oh what a mess oh they say uh from the like concrete laboratory that the these don't explode super much but they don't have this flexible press so concrete doesn't usually explode it's just our press that makes makes the explode because table stretches so much when you press it down and when the concrete lets let lets it go then it really goes yeah but we're going to clean up this and put the last one in okay then the last one this the same concrete as the previous one but this has small steel WIP viers in So based on the first fer thing I think this is about the same strength but it's going to stay more intact when it goes so it's not so prown to like going all over the place after first small crack and the steel vipers inside of this they are doing the same thing as the like regular steer reinforcing things so they're not adding like compressive strength that much concrete is already plenty good on that but they make it better on like other directions so we are probably cannot see the full benefit of th here on this test and here we go the PR loud as hell he je yeah I was pretty good on like pretty good on like seeing the future again we have the unfortunate table situation but I can fix it h that went well yeah but the thing split in two the the steel wires are much bigger than I thought they are quite big yeah o Che those at the back interesting that they can just mix them there like so large yeah let's have a let's have a look on the high speed I think that's going to be interesting right through the hey check oh there is like small things going on yeah before the thing and then it goes yeah there are some metal strings also flying yeah those are like extra SHP now yeah boom yeah really interesting and here are the results and they are actually really easy to calculate because the first number on the concrete type thing it means how many megapascals the concrete can take of pressure in this specific test and then the next SEC second number that's the MEAP pascals on like Cube test but we tested the cylinders and and I calculated the expected results that these have to pass and they are much much stronger but that's partly because these are quite old these are made on start of the summer and it's now Christmas so they're quite old usually these are tested after one month and the concrete keeps getting harder after that yeah but I think this was really interesting and I have still five more samples so if you have some other ideas that we should test with the concrete please let us know and that is all for today thank you for watching and have a nice day
