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).

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

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.

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.

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

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.🙏💓

[Melogode]

The part where he started talking about the clinker and the clinker cooler (02:10). It reminded me of that one Rick and Morty episode with the Plumbus. 😅😂😂😂😂

A good general knowledge video. Important information all in one place. Well done!

[MrBonediver]

Worked at a cement plant for a few!! Raw meal is cooked to become clinker, then mixed with gypsum to make cement!! Mix cement with rocks (aggregate) becomes concrete....

I do construction work and I never actually knew what cement was made of. It can be a lot of physical labor though especially when doing larger pours, or working with drier concrete. I’ll bet working in the rock quarry blowing up rocks and operating large machinery would be super fun though

[MrProgrammerGuy]

This was an VERY well made video. Clear, concise and well explained. Great job!

[karihardarson]

The video is very well made - but the background music is intrusive.

[xBloodXGusherx]

This puts into perspective how complex something so common is..

1:40 The narrator says: A long "cyndrilical" furnace...
instead of cylindrical.

[davidtruchon]

where is the guy that scrape the rock in the picture

[fwengsolutions]

A cyndrilical furnace - that's something I'd liketo see! (1:44)

[edwinbasuki]

Retired RM, Kiln and CM operator here..very good explanation.

[andreaskashungu]

Is this Ohorongo Cement from Namibia am seeing at 2:43 to 2:57? Proudly Namibian..

[JoyKumarShil-ew]

Before saw this video i dont know how to make cement but after seeing this i have been understanding it is more tough but we think that it is very easy but reality it is too much tough😢😢😢

[RJ-zvvw]

Wow.This is wonderful. Thanks for sharing.
