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.

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.

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

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.

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 ;']

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.

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

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.

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.

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

Fascinating as always. So efficient working process. The biggest trick is spinning the concrete to evenly distribute them into a hollow cylinder. I would not want my car to argue with one of these. I think the reason the columns are cured at elevated temperature is the secret of creating prestress concrete. As the temperate is raise the steel reinforcement bar/wire expand more than the concrete. Once cured and returned to ambient temperature, the steel want to contract and hence imparting tensile stress on the concrete and reinforce it.

My father was in the Korean War serving in the US Army in a Corps of Engineers construction battalion as a surveyor. The battalion specialized in Railroad construction, bridge repair, airfield construction. And demolition of same. The Americans were greatly impressed with the use of prestressed concrete by the Japanese throughout Korea. They were further impressed about the skills of the Korean labor force and Korean supervisors. I can only imagine how impressed he would have been with this.

The Steps at 0:45, 2:23 and 5:15 belong together in a way. They attach 2 Plates a 2:23 one is hocked into the knobs at the end of the steel wire (created at 0:45) this one remains in the Pile and is used to attach it to other stuff during construction. the other plate bolts into the holes in the first one and has a central hole to wich a thick screw is attached in 5:15. What they are doing at 5:15 is an extremely important step. They are pre-tensioning the Steel wires (pulling very hard and fixing in pulled position) in 5:34 you see the bolt that keeps the Steel in tension and is attached to the plate from 2:23. This pre-tensioning makes the Piles much much stronger than ordinary cast in place concrete piles. This process is also almost impossible in ordinary construction and really only done in pre-cast concrete (except in bridges). In normal concrete you have to develop cracks for the steel to take any load. With this method the pile may stay crack free depending on load.

Центрифугированная опора. Хорошая, но очень хрупкая вещь. И дорогая. В Союзе повсеместно использовали так как давало экономию на бетоне при значительной высоте (центральная часть опоры или балки не несет нагрузки, а только добавляет вес, поэтому двутавр крайне эффективен, а рельс похож на двутавр). Но есть проблема - химия и токи утечки съедают опору напрочь. В Новомосковске, есть несколько опор, которые повернуты в сторону комбината. Там уже нет бетона. В Самаре сколько этих опор вандалы попротили. Сейчас переходят на оцинковку, но суть не меняется.

This is so cool to see a smooth surface tube being formed just by a centrifugal force from spinning the mold... Remember, there was no cast inside the pillar, only on the outside. That means they have to use the same carefully measured amount of concrete mix each time, with controlled dispersion, to obtain the same wall thickness.... Lots of effort went into developing this technology.

@@anoirbentanfous Concrete contains more water than you think ... My guess is that if the steam is higher than 60⁰C, it will cause the water within the concrete to heat up, with problem that, due to thermal mass, the water inside the concrete may boil off, causing unseen voids within. As this pillars are in compression, those voids may start creating microfractures, from one void, to another, until, even with the reinforcment, will cause the column to go out of spec, in terms of loading strength. Have too many go out of spec, combined with the wire starting to rust, due to moisture collection, and, quite literally boom, you have a structural collapse ...

Steam does not exist at 60 deg C, only at temperatures above 100 deg C......... what may be happening here is Steam is being introduced and used to maintain an Air temperature of 60 deg C within the curing "oven". The humidity may also be useful for ensuring the concrete doesn't "dry out" too quickly during the curing process. Otherwise the system would be inefficient by turning fuel in to heat to make steam, rather than just using fuel to make heat in an air heater, to cure the concrete?

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 🤯
