Bro took drug for alarm
So how is the great leader? 🤣
how thick are the slabs?
Those siren noises and ice cream truck music would drive me crazy working there
I did that exact same work decades ago, just for a few days, it was demanding. The most impressive moment is they put the cables into extreme tension before pouring the concrete.
Warning lights all over the place and loud horns. Everybody's going in worker's emplacements with thick steel doors, in case of a cable snapping. It's no joke.
they had laid out cables on friday I accidentally nicked one with a welding stinger over the weekend. I told them about it and they pulled it anyway. It held till the machine was 250' 1/2 way down then it snapped and got balled up in the machine. lmao
I've seen a rope go through a the rear and front windshield of a 4x4, let alone a steel cable!
I struggle to imagine the damage a snapping steel cable could cause.
Many horrendous accidents have occurred when tow ropes, tow cables or tow chains snap on vehicles. The stored energy is immense and God help anyone that gets caught in the whiplash.
I thought it interesting that even after cutting through the pre-stressed cable, it showed only minor shrinkage from the cut surface.
We did decades ago in Spore and we used beam for stressing and not single tendins
Quick explaination on curing: Concrete is mixed with water to trigger the creation of crystals between the particles in the concrete which cause it to get hard. Thus, the wetter the concrete, the better it cures. That's also why they cover the slabs with blankets, so they don't dry out. And that's also the reason why you can actually build under-water structures in-place with concrete. Interestingly enough, concrete also binds the water permanently. So when you see concrete, it's actually soaked in water, even though it is dry.
Nice that you can make these videos. If anyone tried this in the USA, all the companies would refuse access, fearing you might get hurt and sue them.
how efficient and clean working
OK, a different question then, how are YOU doing?
Couldn’t be better! Thanks for asking :)
몰랐던 많은 직업이 있고
많은 직종이 있고
모두들 열심히 사는모습
Салам алейкум я из Кыргызстана 😀👍 🇰🇬🇰🇿🇰🇬🇰🇿
생산 효율성과 품질은 아주 아주 좋아 보이네요
Mr. Kim nice video thank you.
4:55 놀랬슴다
не знаю почему у меня в рекомендациях подобные видео.... но мне нравится))
Мне тоже как-то подсунуло. С тех пор залипаю
Приятно смотреть на хорошую работу.
Turn on closed-captions, thank me later.
Informasi menarik dan menambahkan pengetahuan.. Salam ukhwah dari Malaysia sahabat semua 🙋♂️🇲🇾
Never seen such a clean precast factory before, very impressive
Parabéns belo vídeo.
🇧🇴 Fans n1 👀 bolivia saludos cordiales desde Sudamérica Santa Cruz bolivia 🇧🇴 excelente okey 👍 💯 puntos maravilloso me encanta ver este tipo de videos 📹 okey 👍👀👍👍💜👍👀👍👀🇧🇴😊
Strong and nice , Korea really strong in work.
if you don't turn on CC idk why you are here..
Dots. And human.
Très impressionnant 👍👍👍
Korea always becones a leading country...!
Neat video, great personality.
informative videos. plus, i like your sense of humor 😜
1:50 that's some eerie sounds playing, think I'd go crazy being a worker and having to listen to that all day.
Amazing seeing those slabs formed by extrusion , I'd been expecting the use of formers .
Siren sounds like 'the clangers' ,a british kids program from the 70s .
Concrete on a grand scale!!
Nice bem feito
Your CC english is OK, man, no worries ❤ Thanks for your hard work.
Muito interessante
Титры просто шедевральные !
The music is so strange but cool!!!
Работал на подобной линии 10 лет назад. Только механизации было поменьше
Musical cables! Für Elise fills the factory 😂. And 2:14 Clangers, without the soup dragon. Great video as always, brilliant text as ever.
I’d go crazy if I’d be hearing a tune that much during the day, no matter if that is Beethoven or Lady Gaga.
and the Oscar for 'Best CC Comments in a Korean Documentary' goes to..... Factory Monster. (standing ovation from several people)
Wow Thanks :)
I agree. Your commentary is very funny.
👏👏👏👏
👏👏👏👏
Yes, I always laugh, very cute sense of humor!
BRILLIANT
Классные титры
Работал на таком производстве.
Только из механизации у нас был миксер,совковые лопаты и модернизированый отбойный молот.
А так,все то-же самое, цемент, щебень, вода и арматура 😂
Man, don't worry about your English, your videos is pretty self explanatory .
Make more videos about industry, and Thank you !
I appreciate that!
Wow. Its amazing
1. PS 콘크리트라고 부르는 슬래브이다.
2. 미리 강선을 긴장해서 배치하고 콘크리트를 타설하는 공법이다.
3. 강선을 자르면 바로 스트레스가 도입되기 때문에,
"프리텐션" 공법이라고 부른다.
반면,
콘크리트를 먼저 양생한 다음,
나중에 강선을 강하게 긴장해서 스트레스를 주는 것을,
"나중 스트레스" 즉,
"포스트 텐션" 이라고 부른다.
4. 위 영상의 경우에는,
강선이 아래 쪽에 배치되어 있다.
때문에,
강선에 의한 압축력 때문에,
슬래브가 위로 솟아 오른다.
통상,
PS 콘크리트 빔이나 슬래브는,
휨 모멘트 때문에 이렇게 중심축에서 벗어나게 긴장재를 배치하고,
그 결과,
프리스트레스를 도입하면,
빔이나 슬래브가 위로 솟구치는 현상이 생긴다.
5. 너무 강하게 긴장하면,
솟구치다가 콘크리트 중앙부분이 똑 부러져버린다.
물론,
애초 설계때부터,
이렇게 프리 스트레스를 도입할 때의 모멘트로 인한 파괴가 되지 않도록 한다.
6. 위로 솟음이 발생한 빔이나 슬래브는,
사실 중앙부의 인장 응력이 파괴에 가까운 상태이다.
따라서,
"내가 많이 들어 봤어!" 이러면서,
위 영상의 슬래브나 빔의 한 가운데 줄 하나 걸치고,
크레인 등으로 들어 올리면?
바로 뚝 부러져버린다!
شكرا على الشرح 😊😊 لكن أين تستعمل هذه الخرسانة تحديدا 🤔🤔
That is a very impressive operation.
I think listening to that Ice Cream Truck music all day would have me chopping up my co-workers with an axe by the end of the week.
Thanks,Be Safe
Hyvä video. Kiitos 👍
Joo. Paremmin konet kuin Parma! 😂
Looking forward to your next video.
More to come!
Not only does Korea make the best cars in the world, but also the best concrete beams. Well done. Great upload.
but its Italian technology )))
Thanks for sharing each one teach one there is no need to keep information for all of humanity is only here for a short time we are all just passing through
Just say "Great!" - after all, Kim is the most common name in the South as well if I'm not mistaken - so there is bound to be a Mr. Kim who's doing great 🙂
Mr. Kim that they r always asking is the one who is in the North. That’t why I keep on saying “Ain’t North” :)
@Factory Monster sorry about the people who think they are being clever but are actually idiots.
잘 보고 갑니다!
This is so cool
Good video. Wonder what the weight of each is?
Хороший контент 👍
Хороший понятный перевод 👍
Спасибо! 😊
what is the strength of concrete and what is it usually applied for? is it strong enough to applied for bridge?
نتمنى أن تتوحد الكوريتان في سبيل ازدهار هذا البلد.
Love the videos, thanks for sharing. ❤❤❤
The workers in that factory must be sick from hearing Bagatelle in A minor, or Für Elise, by Beethoven all day as some the machines move around playing it as a warning... 🤣🤣🤣
Cast in place reinforced concrete has better structural integrity than a building assembled with the prestressed units shown in this video imho,
Clear as mud.
ESSA CARA Q FICA TRADUZINDO TEM UM BOM HUMOR 😊
우리나라 기술력..어쩔~~~~
I like how the different lines/cats/production lines have different sound design, it probably helps synchronizing everything, as well as informing workers of everything going on without the need to look
Great Video. Please give my regards to Mr Kim!❤
I very much enjoyed this video, as well as I have enjoyed all the others that have shed so much light on the wonderful people of S. Korea. I also found your comment about having a year to study English interesting and very brave! There are so many Americans who have not at all mastered their own language, nor care to! It’s a very sad testament to the degradation of the U.S. public school system. Alas, I digress. Thank you for your diligent work on the videos.
Хороший завод
Ich würde wahnsinnige werden, wenn ich den ganzen Tag die künstliche Musik von Beethoven hören müsste ...
Very good, but how is Mr. Kim doing?
HEY
I thought pre-cast pieces like this needed a plate/anchor on the ends to hold tension. If they are able to cut the cables like this and still hold tension, then I learned something else today!
You are thinking of post-tensioned slabs.
I think :D
The friction force between the cable and set concrete is more than enough to hold the tension.
@@PedroPereira-si3sy yes that's correct. These are pretensioned and the concrete sets around the cables, gripping them along the full length.
そうゆうわけにはいか無いでしょう、
ワイヤー構造では、回転しながら経年変化とともに緩むでしょうね。
両端にストッパーは、必要なのでは。
それと、コンクリの打ち方・締め方が緩いので、
とてもじゃないが強度の確保はでき無いのでは
One of the advantages of tension before pouring the concrete is that when the external tension is released, the steel expands and clamps itself.

Great video, thank you! What is concrete and reinforcement grade?
Работал в фирме которая делала отечественное оборудование для бетонных заводов и подобных производств. Две машины знакомые. Только уборщик у нас другой делали.
Very cool.
♥️👍super, I like it 😊
Ill give you a year 😂. Your videos are the bestest.
Over 1/8” strand slippage. Top of hallow core showing signs of mix being to wet. Curious as to next day breaks.
Great video
How are the cavities made, did I miss that in the process?
Those musical warning alarms would drive me crazy.
What is with the music. It must drive them crazy. I would lose my mind.
Wow.
Szokás szerint remek videót készítettél. Habár a beton öntés-falformázás egy kicsivel több figyelmet érdemelt volna.
Great
i do this kind of work at the moment.
I've drilled into these sooooo many times n there was one time where the voids were full of water and I had to wait around 5-10 mine before I could stick the concrete anchor in
Those are probably from the North
@@Factory_Monster 😅 LMFAO 🤣
Post tensioned is safer but pre tensioned much more exciting.
I’m interested in the sounds & music the factory uses. I guess it’s to reduce stress but also are safety signals. I’d like to learn more about that.
What are those sounds for
What kind of admixture being used is type f or purely water on it
Tnx
Нихао!!! Как дела у товарища Ким?
what's the strength of concrete and how many wire strand used and also the size of wire strand used
THANKS and it's covered so it will cure slower. Slower is stronger. Thanks again.
The covering keeps the concrete from drying out. Water is necessary for concrete to cure. Parts that dry out aren't properly cured.
@@GilmerJohn That's what i said.
In the Philippine is already have this, maybe philippines is the first making this kind of plant in free cast
한개씩 나온다면 배수로 사용가능 가격만 저렴하면
работал в цеху ремонта и изготовление форм жби . тут более все технологично
Funny comments, love it.
How stress given to wire for hollow core slab
Good video, ı like. I cant but one of them but like and subscribe you 🙂 good luck to more videos.
И что стальные тросы из мелкой проволоки лучше, чем стальная арматура? Очень сомневаюсь. Да, вы скажете про предварительно напряженный бетон, но все равно прочность на срез у арматуры такого диаметра будет куда выше, как и ее характеристики.
Было интересно, спасибо.
korean is best in contruction
Unreal!!! Who on earth dreamed this up? My God what an undertaking to build this manufacturing process. Mind boggling!
Maravilhoso!!!!!
