Hi Tyler, would be impossible to sleep in your class! Love your videos!! Thanks so much for using this platform to teach and share your amazing knowledge! You actually funny too sometimes! LOL. Keep up the good work!!!! Please finish entire video before adding additional video ads on screen.
Could you make a video for plain simple people that just want to know exactly what type of cement or concrete to buy that would be strong yet still affordable but also easy to use to put in holes for fence post or even inside fence posts and if you think that is needed or not plus what kind exactly to use for your driveways or steps or whatever instead of getting all sophisticated and technical and just tell people exactly what they should buy at their local Home Depot or wherever and tell them exactly which bags to buy and if it's premixed concrete or if people are going to mix their own cement with sand and gravel and exactly how much sand and gravel they should put with the cement and how much water exactly to mix with it all so that it's still strong but also able to be worked with and why? I think a lot of people would like all these simple questions to be answered clearly!
What are your views on the use of Portland cement for mortar and its effects on bricks? Some say that it is detrimental to bricks in the long-term and it is better to use lime mortar as it allows the mortar to be sacrificial rather than the brick itself. Also they say that Portland cement increases damp and humidity inside buildings as it prevents the water vapours from escaping. Sorry for the essay!
Persians have had sarooj mortar since atleast 1500 years before christ which is hydralic. The greeks and etruscans used hydralic mortar long before the romans. Minoan palaces where constructed with hydralic mortar. So romans did not devolop it. And if your talking about siliceas concrete look towards nabeateans who built petra they predate rome and used concrete to make cisterns.
Very interesting video but the end is missing, no explanation how the portland cement gains strength faster and why did the previous types gain it slowly, was it due to the time for CO2 to diffuse into it to form carbonates? The portland type does not form carbonates or does it already have the carbonates when water is added?
From your discussion of Roman cement around 8:00 is it correct that we cannot just take Portland Cement - and add volcanic ash to that directly on our own - to recreate something similar to Roman cement? Apparently, when we mix these together another industrial process that cooks these at a high temperature is required?
I have a question for anyone who knows about cement …. Did Native Americans use cement anywhere in North, Central, or South America between 2500AD and 400BC? Any insight will be greatly appreciated
Tyler I need to understand external suplimental heat on cement castings . I'm making sheds for ranch feed storage out of Air Crete - I wish to make it strong enough to resist animals
Grew up next to the Saylor kilns in Coplay, PA. This area was once the cement capital of the country with dozens of companies due to the large limestone deposits in the area. There are still 4 plants in operation but all foreign owned now.
Sad that you didn't mentioned Louis Vicat, he's the one who found modern concrete in 1814, and made his work available to all for the sake of science, not royalties.
You've bought into the CO2 hype. CO2 increase has always FOLLOWED (lagged) temperature increases , even the present day high priests of climate change do not have any data/graphs that shows otherwise. First you get higher temps, CO2 follows much later. CO2 is good for the environment if you like green things.
Whatever the fact may be, or whatever your beliefs on climate change may be (I don't think anybody will change your view) -- it is still incredibly stupid to pump huge amounts of pollutants into the air that WE BREATHE, the waters we drink, and into the entire eco-system, as well as to use enormous amounts of limited "fossil fuel" resources unnecessarily or wastefully. ... not to mention all the other by-products and corollary after effects of these industrial processes on our health and the health of all creatures around us that just happen to support our existence and make life interesting / beautiful.

... at last I found complete explanation of its chemical composition. Many thanks! Great video!
This is very interesting and well done presentation of the history of cement

GREAT VIDEO !!! SO SO UNDERRATED....WHICH IS NORMAL BECAUSE NORMAL PEOPLE ACCOUNT FOR 70% OF HUMAN BEINGS...THANKS AGAIN, I WILL DOWNLOAD IT RIGHT NOW

Sorry for the essay!
Very clear explaination Thamks a lot
Thank you, truly.
That was really really interesting. What a great channel. Thanks for your videos.
can i use wood ash ,slaked lime and salt(NaCl) to make some type of cement/concrete hydraulic or not?
Thanks for this!

Great Video Tyler.

I would love to know the answer to this as well. Fascinating topic.
What do you think about the k 2019 documentary about the pyramids being made with non hydrolic cement like you talk about here?
Well explained !! I did not know about the Portland patent !!
Thanks for watching.
No problem.thx

If suppose no volcanic site nearby ,than how about stone dust ,is this two similarity ???
it propably needs to be cooked.

9:00 Some Men Just Want to Watch the World Burn Mr. Wayne
lime without sodium how it breaks silica in the crystal to make the form c-s-h?
the what?
👍
