Is Cement and Concrete the Same Thing

- With a background in materials engineering, Jordan provides a comprehensive overview of cement and concrete in this informative video, and explains what sets them apart from each other. Drawing on his experience working with concrete as a design-builder, he breaks down the chemical components of cement and highlights the variables that impact concrete's strength, porosity, and workability. Jordan emphasizes the importance of the cement-sand-gravel ratio and notes that concrete has high compressive strength but low tensile strength, making it prone to cracking under tension. With clear explanations and helpful visual aids, this video is a must-watch for anyone interested in the fascinating science and practical applications of cement and concrete.
Literally 10s of people found this video useful... and I'm one of them. Thanks !
KK doesn’t know what she was missing 😂
You were a nerd in high school too! Though I don't recall ever getting into a discussion about the difference between them, I have wondered. Thanks for the clarification, funny guy.
Boy are you getting the flack! Thanks, though my father was a highway engineer in California, and I’ve listened to his concrete/seement lecture since I was 6 years old . 69 now so can’t imagine the number of times old dad imparted his wisdom over the years.
Did enjoy your take on the subject just the same. You always bring a smile to my face.
Cheers buddy!
i don't even know when i subscribed, but this is an awesome video. Well Done👍
I appreciate the explanation and the pronunciation of 'cement' :)
great video, thank you, looking forward to your follow-up - rebar :-)
To be a pedant, I would say it's more relevent to be referring to the 'strength' increase over time, rather than 'hardness'.
As a side note, an interesting stroke of luck regarding reinforced concrete is that steel and concrete have almost identical coefficients if thermal expansion, meaning the two don't pull themselves apart with temperature change.
Bro, how do you not have waaay more views? As for concrete, I'll take a vid on anything about it. PSI ratings, insulation vs thermal mass, rebar/rebar alternatives, etc
Liked your segment
Tomayto tomahto! Thanks for the lesson about concrete and cement. The funny story was a bonus. The comments about pronouncing cement had me laughing too. I mean, I have always pronounced it see-ment. Maybe it’s a southern thing. Or a tomahto tomayto thing.
I so appreciate the detailed explanation! You are hilarious, thanks
And that's only portland cement! There are also pozzolans like fly ash or silica fume, natural pozzolans like metakaolin, and ACMs like calcium aluminate, calcium sulfoaluminate, and geopolymers, and that's just the ones I can name off the top of my head.
Just not at the prom if you want to still have a date at the same end of the evening ! ;)
Building 28’x50’-2 story Metal barndominium Home. 3,000 psi concrete. 4” slab. 24” deep beams throughout slab w/ 1/2” rebar in beams. Slab will have 3/8 inch rebar 18 inch on center each way. Will adding fly ash to concrete make it stronger and less likely to crack. Is fiber mesh better to add, than fly ash ? building soil up 12” and compacting it on pad. I heard putting 4” of crusher run base on top and compacting It will allow water under the slab to drain. Concrete and excavation contractors stated they never heard of that.
Referring to concrete as "cement" is like referring to tyres as "rubber".
Tires.😏
@@andrewkennedy9704 Ok, Yankee.
@@NiceMuslimLady 👍
I was into til he topic dude…. Could only take about 8 see-ments before I had to leave though.
Are you sure she wasn't turned off by the way you said cement? I'm sorry, but it's not a hard e sound.
You discussed concrete at the prom instead of her dress and how pretty she was? She should have kicked you in the shins before leaving.
So Roman aggregate is insanely high compared to modern, right? Is that part of why Roman concrete is so durable?
FYI: nerd though I am, even Roman concrete isn't romantic. Cool yes; romantic no.
