How CEMENT is Made

[@abcdef-qk6jf]

I used to work at a cement factory. The video is factual correct without getting into too many details. Modern grey cement production uses a tower with a calcinator and a cyclone - the cyclone removes a lot of water very quickly. You need less heat to remove the water. The production is sped up multiple times making it far more energy efficient than the rotary kiln. Cement production uses a lot of waste products like the ash mentioned. Waste has become a ressource - you pay for.... Cement production releases a lot of CO2 - however a lot gets trapped again in the process of curing (when the cement hardens).

[@ryanbeard1119]

Yes. Please tell the lefties that cement when curing natural sequsters C02.

[@wp2746]

Thank you for sharing, glad to hear co2 gets back into the concrete.

[@cattnipp]

are you an engineer?

[@annunacky4463]

I did the control systems for a preheater precalciner system. It had a short kiln…the clinker cooler was the hardest to keep smooth control.

[@northlondonmasons107]

Cement absorbs Co2 ? Thought that was just lime ? Cement hardens from hydration though right ?

[@thomassmith2058]

Cyndrilical! Nice.

[@ironwill4035]

It's 5am in the morning and I'm learning about cement...pretty dope.

[@davidjaap2130]

Retired R/M driver here. Did a good job explaining about cement. The ancient Egyptians had their own version said to contain lava ash. I know this vid was about cement but maybe you could do a series focusing more on concrete.🙏💓

[@robinpage2730]

It was the Romans, not the Egyptians. Volcanic ash, called pozzolana, or pozzolan, was mixed with slaked lime, and that mix was mixed with sand and gravel to make Roman concrete. It lasts for thousands of years.

[@goodcitizen3780]

​@@robinpage2730 ...and cures in seawater too!

[@annunacky4463]

@@robinpage2730 I heard it also had tiny chunks of sea shell embedded in it. Seems the shell was a reservoir of calcium carbonate that seeped into the surrounding cement material over eons and sustained its structure. When we made it, it was all ground very fine for strength and fast set. The Roman stuff lasted, well it still lasts…

[@darthvader5300]

​@@robinpage2730 Pozzolana is not just a form of volcanic ash but as a sandy form of volcanic ash made out of micro-particles of micro-porous silica almost like diatomaceous earth to allow 10,000 times more surface area to react with the burnt quicklime or slaked lime to form a NON-POROUS calcium silicate which is also very strong. Since the late 1960s many scientists and engineers has been trying to find ways to improve on this principle of calcium carbonate to silica inter-reactions. In the Eastern Roman Empire they have no pozzolana or pozzolana sandy volcanic porous ash but they instead used a substitute called crushed and powderized bricks which has been crushed and grinded until it is as fine as white flour. How long it will last? One archeologist demonstrated how that product is made by mixing an equal volume of burnt quicklime and powderized brick powder and adding sufficient water to form a mortar and slap on on a rock wall wet with sea water to make it water proof and he said "IT IS GOOD FOR THE NEXT 5,000 YEARS!" Others use either silica sand with a silica content of 95%, or silica brick with a silica content of 97% or, quartz-quartzite-diatomaceous earth with a silica content of more than 97% up to more than 99%. They are all crushed, pulverized, grinded, powderized to become as fine as bleached white wheat flour so that they will dissolve in water (water is a universal solvent) and when mixed with water soluble burnt quicklime or slaked lime they form calcium silicate cement. One scientist-engineer went so far by mixing an equal volume of sodium silicate (waterglass with a 50% silica content and 50% sodium carbonate content) mixed and dissolved in hot water and allowed to cool into a viscous liquid similar to honey and then mixed with an equal volume of burnt quicklime or slaked lime until both has completely dissolved together (plus some additional water so that he can add a calculate volume of sand and-or graded gravel which are both mica free so that the resulting cement mortar and-or concrete is very strong) that he ended up with a weird form of almost glassy or glazed form of calcium silicate mortar and-or concrete which is very strong and virtually non-porous!

[@stevebuckley7788]

Modern Portland Cement is simply synthetic volcanic ash. You can use any kind of silicate, it's the temperature, heating and cooling times that determine the quality of the final product.

[@The_abdelhafid]

Thanks for the information! I'm now able to start manufacturing cement

[@vicromono4799]

Very good brief explanation accept one. The finishing process is performed at the time the concrete is curing and not after. Usually 3 to 4 hours after being poured, skreed, floated and or fresno smoothed, a trowel, broom or stamp finish is applied. The only finish performed after curing is acid etching, grinding and polishing. 70% strength it usually obtained after 7 days. 90% after 28 days. Concrete can cure for up to 90 years. The Hoover Dam project was still creating heat from curing years after completion.

[@hime273]

I don't even remotely believe that whole Hoover Dam claim. It sounds like another asinine claim to wow and dumbfound the masses.🙄 Are we to believe that they imbeded wireless Tempurature sensors throught the concrete? Concrete Dams are poured in blocks, using a quick curing cement, and each block is essentially cured by the time another block is poured on top of each block. Are we to believe that the Hoover Dam is the one concrete structure in the world that somehow created an anonymous forever lasting chemical reaction that defies Physics?

[@vicromono4799]

[@Quizzicality]

I run a concrete plant. There are a few batches (recipes) we use all the time for things like driveways, sidewalks, foundations etc but for special projects (large commercial jobs etc) there are hundreds to choose from and my company has experts that can whip up a new one whenever needed. There's also a lot more than just retarder. There's water reducer which also increases the strength of the concrete, fiber (steel, plastic and glass varieties), and we can even change the color of the concrete.

[@Factora_eng]

I would definitely qualify as a retarder. Are there job openings?

i think concrete isn't in tensile strength but more of it's compressive strength (crushing force) that's why we have different strengths in mpa or psi. tensile strength refers to reinforcement bars (pulling force)

First, you take the dinglepop, and you smooth it out with a bunch of schleem. The schleem is then repurposed for later batches. Then you take the dinglebop and push it through the grumbo, where the fleeb is rubbed against it. It's important that the fleeb is rubbed, because the fleeb has all of the fleeb juice. Then a Shlami shows up and he rubs it, and spits on it. Then you cut the fleeb. There's several hizzards in the way. The blaffs rub against the chumbles, and the plubus and grumbo are shaved away. That leaves you with a regular old plumbus!
