Cement Manufacturing Process with the Portland Cement Association

[@l.halawani]

I'm studying construction engineering and we're just starting to work with cement chemistry, it's a bit tough for me and the shorthands for the elements make it so much more confusing. Like naming the calcium oxide C - wth? C was supposed to be carbon *dies a little*. So I spent yesterday hours trying to figure out (among other things) how from calcium and silica we get to carbon and sulfur xD. Your video made things clear, in fact I can say I completely understand this process now and it all makes sense. It's also the best video explaining how clinker is made and what's it made of. Huge THANK YOU man. This video deserves more views and more thumbs up. And the 11 people who pressed the thumb down are the jealous competition who couldn't explain things as well in their productions. :D

Thank you so much! Just joined cement production. Your video is the most useful, what I`ve found. Great job!

[@TylerLey]

Thanks for watching! I have lots more videos you should check them out.

[@abrilramirezh.8505]

Thank you ! That was an amazing explanation, I love this process too

[@TylerLey]

Thank you so much!!!

Loving the videos. I'm a concrete finisher but a doctorate in business so I love seeing the chemistry and entire process. Quick couple of questions: 1. What determines the optimal size of the clinker? Could we not pre-crush it smaller to the size of a pea, grain of rice, or powder and then fire it through the kiln? If we could, it would take less energy, be less expensive, and potentially faster. 2. Where does silica fume and fly ash fall into the process, if at all, and how does that affect the price of cement given that silica fume and fly ash are byproducts anyway? 3. The large US steel mills lost ground to mini-mills that would focus on one type of steel (e.g., rebar). Clay Christensen talks about it from Harvard Business School and how they took over the market. Is there the possibility that smaller cement mills with more modern technology could be used to displace the large mills. It seems (at least in Canada) that there is not a lot of competition in the cement production world. I think we have only three main companies that supply it in Canada. Various other brand names are owned by them. 4. Are there some places in the world that are better for generating cement? I lived in Puerto Rico on the south side for a year and a company there still mines material from the hills and exports cement powder all over the place.

I really enjoy seeing your explanation, greetings and thanks from a Mexican

[@raducojocaru3501]

enjoyed your explanation and the energy. the animation was a bonus too. thanks.

[@kuldeepsankhat8803]

sir, why are you so awesome, i wish you taught in my university.

[@malisehiddenrock7162]

You are such a great teacher! Well done

[@rezanadimi3312]

Many thanks for your full of energetic presentation. In a short time, you shared a lot of information.

[@TylerLey]

Thank you so much!!!

[@khalidsalah8482]

Amazing video thanks

[@sunilprajapat4448]

Thank You very much

[@bambose940]

Clear explanation I like the way u pass on the knowledge to us

[@sitthipongkhunthong6382]

Thank you! for the awesome explanation cement production process VDO. It was clear and get easy to understand. Please keep make the good clip like this

[@newfie-dean5803]

Great presentation!

[@TylerLey]

Thank you!

From what I have heard is that they add limestone to soften the cement depending on the use , like mortar for laying bricks needs to have a little flexibility so they add more limestone to the mix. I could be wrong but that’s what I was told.

Yeah this is a case but one of a primary purposes of Limestone usage while producing CEM1 cements is providing of Aluminate sources (mainly C3A) and Limestone to react and in this way obtaining Monocarboaluminate and Hemicarboaluminate AFm phases which fills the hydration space, decreases porosity and increases the early age strength. Also there are other perspectives of course but it's a detailed topic as other topics in cement chemistry :)

[@mlines8]

Thoroughly enjoying your discussions on cement especially the raw materials aspects. Have you a discussion on metakaolin as a pozzolanic material?

[@LightSpirit24]

Great video thanks very informative.. Can we use solar to help heat up the kiln to save energy?

[@yenezergenene1735]

My lovely Teacher

[@majjood02]

Thank you very much Tyler ..that was really an interesting explanation for the process of making cement which is usually poorly presented..I wish that uni professors could learn from you!

[@rajabwawa7802]

Thank you very much for the information ..great job

[@JW-zr4dk]

Just found your channel great!

[@Dabuilders]

Do you add limestone again afterwards???explain mixing process step please which goes first and last

[@mohananjanikumar1177]

Thank you its very useful , can you just briefly explain about the C3A, C3S

[@TylerLey]

Watch my other videos about hydration. I talk a lot about them there.

[@sunegroennebaek5283]

Thanks for the information. 👍🙏🙏 So from what you are saying.... lime NHL 5 is 25-30% less CO2 intensive then cement? Greetings from Denmark

[@amjadmahmood4355]

thank a lot , very informative video

[@EdoardoJacucci]

Very helpful, thanks! Do you have the sources of the energy consumption and CO2 emission numbers? Is there a report/study?

[@TylerLey]

Check this video out: kzbin.info/www/bejne/qZjagYyZmrOmsLs There are sources in the notes section.

[@stevewaclo167]

What options exist to reduce CO2 in cement production or at least sequester the gas? Also, how was cement discovered and produced?

[@JACRA25]

Tyler has a great video on the history of concrete! kzbin.info/www/bejne/ooGTq4OYoNt1q8k

[@LasseVintherTyron]

Aalborg-Portland. The use of alternative fuels (2018 30 %) and the use of some of the heat from the kilns. I Aalborg about 22% of the district heating comes from Aalborg-Portland (2018 22.000 homes). Search for Aalborg-Portland and you can find more info. (Yes, i Work at Aalborg-Portland 🙂 )

Alite and Belite, they weren't feeling too creative that day!

[@syedomairali7203]

Before it enters the Preheater it goes into a blending silo!!

[@akoponen]

I have long wondered why cement manufacturers don't use large solar mirror arrays to get most of the heat for their production process...large upfront capital cost...free energy thereafter (except for maintenance). Bonus of less impact on the global climate as well as less pollution!

[@l.halawani]

The process of clinker production requires about 2000 dg. C, and it's often mass produced in long (40m+) drum furnaces that work with hundreds of tons of material at once. Imagine the scale of the mirrors required to do this.

Carbon is everywhere. It is the carbon cycle that due to Yahs design, enables life and society to flourish Under the firmament a.k.a. greenhouse, we exist. Not on a spinning ball in a vacuum

[@MrTrulyHandsome]

I am watching this just in case i get isekai’d.

[@mikeb.1978]

This guy is a drag!

[@abdv9908]

Why do you speak about environmental effects of cement manufacturing. Just show how cement is made.
