They use steam curing when it is necessary to have an accelerated gain of strength for the concrete. It depends on the type of concrete used but when it's used, it speeds up production output of the factory enormously. It is used frequently in precast concrete objects that need to be prestressed because the accelerated curing (hydration) causes more internal and external stress (tension) in the concrete, which increases strength significantly. It can be compared with the tempering of glass, where the tempering process causes enormous internal tension and surface tension, which makes it so that tempered glass is much, much stronger than normal glass(*). As long as the stresses in the concrete aren't too large of course, because when the concrete shape deforms too much because of tension caused by curing too quickly, it cracks. Factories like this of course know precisely how fast they can cure, so such cracking will be rare or even unheard of Nice video, thank you (*) A glass "Prince Rupert's drop" (look it up) can be hit as hard as you can with a hammer and it won't shatter, because it was tempered so quickly that the internal and surface stresses are absolutely gigantic. It only shatters if you hit the thin tail of the drop, but not if you hit its body, not even with a heavy hammer swung with all your might

Interesting

It's called release agent, some use diesel oil

Factory monster, I love you romantically.

Fantástico 👏👏

Industrial grade Lego blocks,and proportionally made in the same manner! Amazing welders,and kudos to the geniuses that figured out how to automate those heavy duty processes! As to the steam curing,they would use SUPERHEATED steam,as that is a dry steam,most of the ambient water vapor is squeezed out! When that was used on locomotives,the whole lubrication systems had to be changed,as Saturated steam,do a degree was self lubricating! Minor data,on a rather interesting use! Thank you 😇 😊!

Hey! Thanks for translated subtitles! Especially Ukrainian. I see machine translation wasn't really good, but still... thanks!

That oil is typically called release agent, although oil does still work in most cases. That automatic rebar cage welding machine is amazing, I never could have imagined something like that going into the production of concrete pipes. Thanks for sharing this!

👍👍I want one of those pipes in my kitchen😂. Welder was pretty cool, amazing automation

Same here on the welder!

ik realy like the welding machejjn

Release film, release agent, and other descriptions. But the concrete guys just call it oil.

Production production production

I don't want a giant concrete pipe in my kitchen 😰 *like* *like* *like*

¿Si le agregan mas agua a la mezcla de concreto hara que esa porosidad desaparezca?
