The steam curing is probably needed for strength. Concrete always cracks as it cures - there's no way to completely stop ALL cracking. If it develops large cracks, the concrete will be weak, but if it only develops micro cracks that you can't even see, it will be MUCH stronger. One of the ways you can minimize cracking is by keeping the concrete wet while it cures. That's why when they pour concrete driveways, it's best to keep misting water on them for a day or two. It will increase the strength of the concrete tremendously. Another way to minimize cracking is to keep it the same temperature all over the concrete. And since the center will get quite hot (concrete makes its own heat as it cures), they use heat to keep the outside from cooling off too quickly. And what is hot AND wet? Steam.

[@yudoball]

Thanks for explaining

[@jh-ny2jh]

very helpful explanation

[@saravanakumarsanderan7944]

Concrete cures the more its moist. its a process called hydration and it happens over time. concrete gains its full compressive strength over months. The steam helps penetrate the micro grains of the concrete compared to letting diffusion to the work, which takes longer i guess.

[@Tygor3533]

My thoughts exactly as I do concrete work work myself

[@bobmam5707]

Not really, it's a chemical reaction with the limestone inside the concrete, where if you grind up limestone, bake it, then get it wet again, it hardens up greatly, and it will just keep getting harder the more and more it's exposed to water, with diminishing returns granted

[@NikeaTiber]

Re: your questions during the video The first object they were securing to the steel cage was the baseplate. This is the "top" of the piling, as the piling will be sunk into the ground. The steel building will be bolted and possibly also welded to these baseplates. The steaming helps the concrete cure faster. It hardens better, faster this way. Thanks for uploading this video; nobody will ever see those pilings when they are in use but it is nice to know what the roots of your high-rise look like.

[@EdwardDowner]

That baseplate and later on at the 5:15 mark are also probably part of pre-tensioning the reinforcing bar. To add to the steaming part, it's done after the concrete has had enough time in the centrifugal tumblers (my name, don't know the official name) to set up enough that the walls don't collapse under gravity. No "massaging" is taking place ;']

[@SJR_Media_Group]

This is excellent example of automated high production rate making concrete piles. Adding reinforcement is automated and very fast. We used to lay rebar by hand, tie by hand, cut and bend by hand. The long steel sections are held in correct spacing with pre-drilled steel ends. Wrapping with thinner wire and welding help keep all pieces in proper alignment and spacing. Adding concrete into form and spinning gives a uniform thickness of finished piles. Longitudinal steel is post tension or pre-stressed, adding to overall strength. Sometimes they use a high-early concrete that cures in a week instead of 28 days. Here, the piles are steam cured to quicken cure time. I've seen where they have to make many hundreds of piles for a single job. Piles can be various lengths depending on requirements. They can do all that in less than a week. Fun Video - thank you.

@@Factory_Monster you are welcome

[@shlkyc02]

The plate and the bolts into the endplate at about the 2:20 mark serve dual purpose. It helps hold the rebar steel pattern in place, and it looks like it pulls it into tension. The "P" in PHC stands for pre-tensioned, which is where you pull the steel before casting the concrete around it, and it essentially makes the concrete "tighter". This has to do with the relative strength differences concrete has when it is pulled vs. when it is pressed. The oil is formally called a "form release agent", which really does the same thing oil in a cake pan does. Steam is used to cure this concrete, I'm going to guess because it is hot and wet. Concrete needs a lot of water to cure (harden), and a high-strength concrete has a lot of cement, and therefore needs a lot of water. This is a chemical reaction, so if you write it out, there's no water in the end result. Keeping it hot and saturated speeds up the reaction by giving it plenty of reaction material and energy. I'm shocked they're hollow in the middle, which was a surprise after they spun the cylinder. I normally don't work with PHC piles, and spinning concrete is usually not recommended because you can separate the components and end up with uneven distribution. It's quite a fast speed, so I'm guessing the aggregate mix has to be very uniform to avoid this problem. Thank you for posting, this has been very interesting to me.

[@tomruth9487]

Kevin C Yes you can bet they have worked on every aspect of their concrete mix. You bring up a good point of the different materials in the concrete can't separate when it's spinning and have to stay properly mixed. Not easy to do I imagine.

[@justwastingtimeonyt9952]

Good comment

[@NasirQazi1]

You know concrete. Well explained. Thanks.

[@markfryer9880]

Kevin C. Well commented! As far as spinning the columns goes it was mentioned that they go from speed 1 to 7 while they are on the spinning wheel sets. The initial slow speed would allow the concrete to press against the mold without any risk of deconstruction of the mix and then as the speed increases the centrifugal forces will evenly compact the concrete against the mold. The steam curing provides heat and moisture to facilitate the proper curing of the concrete in a shorter time frame than if the concrete was allowed to cure normally. After all time is money and the sooner you have a finished product the sooner it can be delivered to the client and free up factory and yard space.

[@angelfdez4644]

In 2:20 the operator is just placing the ring. The tension process (stretching) happens later, when the steel reinforcement is placed inside the mold, and continues until demolded. Sorry, I can hardly speak English

I have a degree in materials engineering, and have worked in concrete prestressed bridge beam construction. The comments below are correct. The steam aids in curing the concrete. The base plates are used to tension the steel rebar core. These both help speed the process and make for a much stronger end product. Steel is very strong in tension and concrete is very strong in compression. When you combine the two strengths of each you get an even stronger more flexible end result.

I’ve always wondered, could you make the moulds with ridges, lines & groves so the finished product came out looking like wood. The reason being is it would be possible to replace historic rail or road trestle bridges with concrete poles that look like wooden bridges. They’d be stronger and last forever. I’m sure you’d only need 10 or maybe only 5 or 6 different moulds, as you rotate the poles so show a different side. They could also have flat spots for the angle beams that act as struts and crossmembers and they could be made out of concrete as well.

Steam is used to speed up the curing process. Concrete does not dry, it chemicaly converts the cement and moisture into a hard substance. Heat speeds up all reactions, the use of steam provides moisture so that the concrete mix does not dry out. Without the steam curing they would have to wait much longer before de-molding and it would greatly decrease the factory's output.

Great film. Good comments below. Used to work concrete construction but only with regular formwork for walls, foundations, etc. you can see how the concrete came down to the tube as almost dry. this gives them the ability to form it somewhat, then the spinning spreads it to the outside without having sloshing water in the mix.

The cables are 'butted', these cables are then spaced correctly by the wire that is spot welded in a continuous wrap. When the end cap is fitted it also holds special bolts which have tension nuts fitted to their end. As the bolts are tightened the nuts which fit over the buttes ends of the cable are pulled tight. In similar fashion as rivet nuts are used in manufacturing. A second set of bolts fit only into the mold. After forming and curing the end cap is removed, leaving the tensioned nut. Half of the nut has threat left exposed, which are seen at the end of the vid and will be used in connecting the pile.

You admit if you don't know something, instead of making something up like a lot of the channels which make similar videos. This is weird but I actually look forward to reading your commentary, it seems so friendly yet intelligent :)

thank you and the factory for sharing with us.... im from the US and have operated many concrete boom pump trucks (possibly another video idea?) anyhow mad respect for these guys and this production not to mention the acceptionally clean (in my opinion) work environment.... very impressed thanks again and hello from Arkansas USA

The amazing thing is the mind that conceived the flow of the rods and the mechanism at each stage. That is the engineering feat!!

[@MyNathanking]

8:08: Remember the centrifugal spinners earlier in the video? The centrifugal force ensures that the concrete is spread evenly all around the inside of the mold. That hollow center would be impossible without the centrifugal force. That means that the molds have to be spinning the WHOLE TIME the concrete is setting.

[@asthavarojil4055]

But how can the concrete become tight if is continuously spinning.

[@-_-----]

Awesome! Thanks you so much for the video, and to the workers + managers for letting you film! I can't believe that sucking-device actually lifted that pile out of the mold - that must be some insane suction power....

[@Factory_Monster]

That’s exactly what I thought! the suction power!

[@tomruth9487]

Or I was thinking it was magnetic and so is held by the steel in the cage, but maybe not?

[@Leptospirosi]

I think high temperature in a steamy atmosphere helps the concrete to reach its standard exothermic reaction while curing without depriving it of too much moist on the outside and the inside hollow surface. It is probably the ideal environment for the fast curing concrete they chose.

[@Leptospirosi]

@@lagresomadsl but you don't want it to do that too fast, especially in such thin sections as these. They are heating the casting up to speed the curing reaction and keep it uniform, so they also have to steam it up to slow the concrete loss of humidity and prevent the casting from cracking.

[@josephastier7421]

It is amazing how smooth the finish is on the inside.

[@DigitalOutlawed]

i found that so interesting too, how come the centrifugal force can do that on its own? and how do they measure exactly the amount of cement needed to get even edges and and even width everywhere?

Though i,m an Engineer and design these precast piles but happy to see their construction at factory . Thanks for ur knowledgeable sharing ♥️

[@Factory_Monster]

Thanks for watching :) I respect you design those machines

[@idadho]

Curing with steam speeds up the curing without reducing the strength. The steam heats the concrete and prevents it from drying out/losing moisture. For most chemical reactions, for every 10 degrees increase in temperature, the reaction speed doubles.

Curing is needed because, during hardening process concrete releases lot of heat. If it is not cured, the heat will cause cracks in the final set concrete. U can do the curing by steam or ponding or many other ways.

Amazing👍

[@davidkillens8143]

For such a structure to be high strength, the longitudinal bars must be under a lot of tension. The plate you were inquiring about was to attach the ends of the bars. Basically they do both ends. The operation at 5:15 fastens a huge nut that is turned to apply that tension.

[@Factory_Monster]

What a detail explanation! Thank you for sharing your knowledge ;)

[@davidkillens8143]

@@Factory_Monster This technique is called "pre-tensioning". For example, those lovely arched concrete bridges use this technique (and post-tensioning) to give them the strength they require.

[@ly5046]

In the process at 2:22, the worker installed the plate at the end of longitudinal bar, is that also preparing for the Pre-tensioning?

[@davidkillens8143]

@@ly5046 Yes. This is one end being prepared for pre-tensioning. The video did not show the other end, but it received the same, or broadly similar treatment. One end is static and fixed, the other end is tightened, as displayed at 5:15.

[@tomasdvorak7307]

@@davidkillens8143 Minor correction: the nut doesn't apply tension, it only fixes the wires in the elongated position once the tension had been applied hydraulically.

Heavy industry...it's an another universe. I had the chance to work for one, the most interesting and one of the best work/life experiences i ever had. I could use a machine of 400000 euros and weld with a MIG/MAG welding machine of 20000 euro worth 😍. I stayed only 6 months. After 1 month, with all the coaching of the team and the manager, i was ready for production and was in the green in production time!!! We started at 4:00 and finished at 14:00, sometimes we got to start at 2:00, it was perfect, no traffic jam at those hours X'D. The job was awesome : safety equipment, tools, the products... But sadly, it's not well paid. I couldn't afford to stay there, one of the hardest choice in my career. What kills me the most, is that in Europe, every manual work sector is short handed. Well of course nobody is gonna work for a shitty pay! Really sad and stupid. Because those jobs are equal as being an engineer or a doctor, you gotta be rigorous, if not, somebody can be hurt or killed, if you take your job lightly or if you don't give a damn f***.After that, I worked in Switzerland as an IWS in an office, sitting all day long on a chair...i had the triple salary without the overtime pay. The job consist on coordinating welders, redact welding procedures, keep the welders certification in check with the task they do, etc, etc. I lasted 6 months, it was interesting, i had to work with awesome TIG welders, god welders to be precise. I asked my boss if i could work with them, to learn how they weld, to have a better view of how they work and to perfect their procedures. He said no X'D. How do you expect me to coordinate people and perfect their work procedures if i don't know how they work! X'D epic. That was the second hardest choice in my career X'DDD

이과정이 너무보고싶었는데 감사합니다

[@hannibal6898]

I may answer some questions... Concrete has a "curing" period in wich it's (initially) super prone to dehydration (up to 7 days) and then a late curing period (up to 28 days) in wich it's prone to rupture, you must take care of it for a whole month before it gives you all you expect of concrete... But in fabricated pieces like this you use some additives to shorten all the curing (2 hour to set, 7 days to hydrate, 28 days to strenght) you chemically make it all (sorta) done ASAP, that's where the steam treatment comes from, it heats the additive and concrete to have something we call "high early resistance", reducing the 28 days to one... Also it being full of moisture Will keep concrete from losing any... All of this just to make so the molds are avaliable earlier (those are expensive molds). The most amazing part of this process to me tho was seeing how it was made hollow, by spinning, that process in my head it just wasn't supposed to work lol, but it totally does, it blew my mind... Concrete sets as crystal "needles" and the spinning in theory should prejudice that process, resulting in weak concrete, but somehow they sorted that spinning range and speed just right to have a perfect piece at the end of the 2 hour setting period 🤯
