How Cement Is Made? (Mega Factories Video)

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together. Cement is seldom used on its own, but rather to bind sand and gravel (aggregate) together. Cement mixed with fine aggregate produces mortar for masonry, or with sand and gravel, produces concrete. Concrete is the most widely used material in existence and is behind only water as the planet's most-consumed resource.

Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln. In this process, the chemical bonds of the raw materials are broken down and then they are recombined into new compounds. The result is called clinker, which are rounded nodules between 1mm and 25mm across. The clinker is ground to a fine powder in a cement mill and mixed with gypsum to create cement. The powdered cement is then mixed with water and aggregates to form concrete that is used in construction.

Clinker quality depends on raw material composition, which has to be closely monitored to ensure the quality of the cement. Excess free lime, for example, results in undesirable effects such as volume expansion, increased setting time or reduced strength. Several laboratory and online systems can be employed to ensure process control in each step of the cement manufacturing process, including clinker formation.

Well good documentry. Now latest technology is more efficient by using vertical grinding mills on raw materials and cement side. Hot escpae gases are capture to produce electricity.

This was a good documentary, it brought back memory of my time at the cement plant in Jamaica where I was a pump operator.

[maroofmb]

This video explains the process really well

[Get-into-the-game]

I was just about to say this is Ohorongo cement in otavi, Namibia, southern Africa when I saw the staff uniform and company logo, keep up the good work guys

[chasehopkins]

Gosh I love crushers and mining equipment. My favorite line of work.

[Wallacenawa]

Ohorongo cement in Namibia. I went there in 2nd year of Engineering on a school trip. Glad its featured here.

[storytellerAIhistorian]

thanks to explain whole senario of cement product without steping up:)

[loganwendt]

My favorite part of the manufacturing process was just looking at pictures of the quarry. Thank you for your time

[npcx]

And it all started with a bang !!! The metaphor

[shahzamankhan]

Excellent documentary. Well explained steps.

[edwardhunter]

Thanks, there great peoples in the industries, once apon a time I made concrete, concrete pipes, highways,airport runway, dams, infrastructure for plants, ports for ships, bridges, this country's need more works to be done, brothers just keep it going to have a clean water .

It's CONCRETE! Cement is an ingredient of concrete! I've poured concrete for 20yrs and it drives me nuts when people call concrete cement! 😂😂

[damskiebondat]

I worked at the coal fired power plant before, the coal that was burned & turned into ashes became cement

[ferdinanddiego]

How I wished, there could be a cement factory in my Town, we have plenty of Lime materials in out Town at, Candoni, Negros Occidental, Philippines.

But, we don't have interested investors in here.

[JackKing.]

Take my hat off to the guy or girl that discovered it. Without him or her, I won't be able to do my concrete garden posts 😊

[Aleksanderavo]

This process should be taught in school

[kashifabbasiabbasi]

one humble suggestion: during calcification of cement along with using coal, methane gas, plastic wrapers, plastic wastes along with oxidizer for environmental ecosystem and cleaning may be used. cement industry can contribute in elimination of waste plastic with good supply of oxygen for clean earth.

[KevinCoop]

Largest cement manufacturing plant in the world is in Missouri, USA.

I've had a few close calls in the past, and I've learned the importance of wearing Softgle

[evilelf]

i live a few minutes from a cement like cape canaveral.interesting insight into the methods used and scale of equipment used in the process.
