This video is ideal for me - a non professional with an amateur interest in chemistry, and science in general, but not patient with endless, confusing, disconnected minutiae. Now I have a little understanding of how concrete works, and how it fits into chemistry, construction, ecology, economics, climate change, etc.. Great job!

the disconnected minutiae is the professors not willing it give the technology away.

Big correction, at the start he describes the production of quicklime. Quicklime IS NOT cement. Lime is a component of mortar. Modern cement is Portland Cement, it is made under a different process. There is no lime in modern concrete, only mortar.

The fact that the background music is Breaking Away by Ratatat makes this that much better

Awesome! Simple and profound at the same time, and beautifully animated.

This is great. I have a very small hole in concrete. I am planning on filling it with a dry mix of equal parts cement and sand. After that, I plan on putting drops of water in it. This should allow my repair to have zero air bubbles, fingers crossed.

Love the Background Music, I love Ratatat! and of course the content

This was exactly what i wanted to hear, even though i know little about chemistry. It was interesting to see how they make cement (keeping all the factory equipment aside) & what it chemically does.

Thanks. That was just what I needed. But, was it a mistake when you wrote C3S not C3Si or does it change how it's written somehow? I'm not being sarcastic, I genuinely don't know. I don't understand chemistry but I'm interested.

minute cement, sounds like a good story for a book about chemistry.

So the cristals formations is not a chemical reaction exactly? But why does the ions release heat? What chemical principle is related to this?

can you electrolyte it before it's crystalized with some quartz aluminum? if it grows like a long line like carbon nanotubes

hello sir, i make flower pot from concrete. what if i heated or burn it? does it make faster for hardening process ? (sorry for my poor english)

Which one is better for concrete, pure purified water , Ground water or water that has been heated

There is any step to make flexible concrete in the process? like using microwaves lasers, xray, ultrasound or some technology so you have some parts of the concrete ultra flexible to replace the wire mesh?

You’re summing up random stuff asking if it “maybe does that”. Sounds to me a bit like throwing a drill into custard and hoping magically a Audi R8 appears 😅

Good work. You covered a lot of topics in one Video, great for some people. I would have enjoyed, a Dedicated video on each video. Thank You.

0:45 C3S would be a calcium sulfate, not a Ca silicate. C is the symbol for carbon, S is the symbol for sulfur. Si is the symbol for Silicon. Also, Al is the chemical symbol for aluminium, not A. But minor errors are no problem. Thank you for sharing and demystifying the glories of cement.

@pauldodson2018 2 жыл бұрын

Btw- you wrote the chemical rxn. Ca + SiO2 --> C3S. That would be Carbon Sulfide. It should say Ca2SiO4 (Calcium always has a +2 charge and the silicate polyatomic ion would have a-4 charge).

@d113lll7 2 жыл бұрын

There is a special notation used while discussing chemistry of cement. C3S doesn't mean carbon sulfide. In fact, it's just a shorter way to write 3CaO × SiO2

Dear Swiss Scientist, I am embarrassed to say I have an MS in chemistry and never knew the chemistry of concrete! Thank you!-Paul

Hello, the video is really nice, congratulations! However, in the video it is written that "the needles are C-S-H (not Ettringite)" (1:57)... but I think the needles are actually the ettringite and not the C-S-H. C-S-H is amorphe/multiples morphologies. (en.wikipedia.org/wiki/Ettringite#/media/File:CaOH2SEM.jpg) :D Bye, have a good day!
