There is one mistake in the diagram of reaction No. 5. Fe2O3 is on both sides of the reaction, which is incorrect. On the right side, It should be Fe3O4.

This is the best explanation ever for cement hydration that's available online! Your efforts in putting this together are truly appreciated! I am here to refresh some theoretical concepts before my comprehensive exam next week! Wish me luck!

I'm taking an Environmental Geochemistry college class and this is a great explanation of pourbaix diagrams, although in our class we refer "potential/V" as "Eh" so we call the diagrams "Eh-pH diagrams" instead, maybe its a colloquial thing.

3:33 eq5 Fe3O4

Isnt the gypsum a plaster?

aggregates?

Why is anybody surprised that CO2 is produced by heating the ingredients for Portland Cement. The limestone is literally from dead sea creatures ... the process is liberating the carbon from the dead sea creatures and returning it to the atmosphere where new life can use it to grow.

I’m a senior civil engineering video and this video made me finally intuitively understand how a lot graph works. And the rest of the video is great to I’m about to watch the whole series

Thanks for your videos-- they're clearly explained and helpful.

You said surface tension is acting towards bulk liquid Then why is it said that direction of surface tension is along the surface ?

👍

Just subscribed, thanks for the video 👍✌️

🙏🏼

Sehr cooles video :D

siuu

Danke

How can I make such videos

You should use proper chemical notation, not this cement chemist abomination.

Why do we need to CaOH2 during the reaction of Limestone and Aluminate sources with water, is it because we need a Calcium source other than Limestone, if so why is Limestone not enough as Calcium source?

Dear Sir, Please suggest any reference book or research article related to the capillary condensation topic.

Which app do you use to produce these videos?

Thanks a ton for this incredible explanation!

Instantly subscribed, made more sense than 10 pages in my textbook

This is some good stuff :)...

thank you

Such an amazing explanation! Thank you !!

starkes Video, bringt mich durch die Prüfung morgen

Love this channel, very high quality content, precise info, good graphs, right to the point without oversimplification...yeap, I suscribe to this.

its amazing most of today's concrete will need to be torn down and rebuilt in 100 to 200 years. whoops

Just what I needed... Thanks

Thank you for the informative video team😊

5:35 if final concrete has 4.5% porosity then why aren't we using this material as water purification filters? instead they sell ceramic filters which are much more expensive. But with one bag of cement you can make hundreds of water filters. Why isn't cement used as water filter?

First, i love ypur videos

Banane

was ein schmutz video ich check gor nix

Thanks

nice explanation

Thank you.

Thank you.

Thanks.

I'm gonna fail this fucking test bro

If I wanted to build a stone house to last a thousand years, what mortar should I use between the stones to last a thousand years?

love from india, good video

8:48 Exothermic H < 0 Spontaneous G < 0

Nice

it was very helpful... with nice graphics

Should that reactant 2Fe2O3 be 2Fe3O4 in equation 5 (3:21)?

Good explanation

Wow ! That gets confusing really fast lol I'm going to watch it at least one more time to make sure I'm getting it right. Thank you for being so detailed with the information. And the graphics / illustrations are wonderful.

Well done ! Love the way you married the history, materials and chemistry together. Thank you. Very useful information :)
