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?

Excellent presentation of the science! Thank you
Best video I've seen and wonderfully condensed for quick absorption. Perhaps room for a pun there.
lol
Very informative

Great explanation!

good vid
Looking for dangers of cemical binders.
What does graphene do for the chemical reactions? Especially for the 2D planar carbon?
