Roman mortars and the secret of the pozzolanic reaction
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?
you should use no mortar if you want it to last 1000 years. dry stack your stones.
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 :)
So adding hydrated lime to Portland cement could cause cracking under heat if I herd correctly
heard that is it’s now cows
minute 3:20 the 5th equation is wrong right? it should start with 2Fe3O4 instead of 2Fe2O3?
These videos are pretty sweet. Please keep it up!
Very comprehensive and valuable informatiom
th-cam.com/video/t9KKz7hgzCU/w-d-xo.htmlsi=j7Im5-ZWB8VGd3l5..Noch Fragen?
Keine Ahnung, was das für Physiker sein sollen, die so einen Schwachsinn verbreiten. Es gibt KEINEN Treibhauseffekt in der Atmosphäre ! Der Treibhauseffekt beruht auf der Verhinderung von Austausch von Wärme und Luft ! In der Atmosphäre findet ständig ein Austausch statt!
great video. A huge thank you
Awesome video
Useful information keep on the good work. I’m a civil engineering student and I find your channel pleasant.
Thank you so much for educating us. I have a request, could you please post the references in the description that were mentioned at the end of the video for easy access to the audience? Thank you.
