- In this video, Cole Sonafrank, assistance director of research ay CCHRC, explains basic ingredients for geopolymer cements and the importance of using locally available materials in Alaska.
Geopolymer cements use waste materials as a binder and are stronger and more sustainable than conventional Portland cements. CCHRC has studied more than 600 recipes of geopolymers made with use fly ash, a byproduct of coal combustion, from local power plants.
I like this man's energy. so chill.
slow and very thoughtfull
You mean sane. Most humans were like these several decades ago before the financial terrorists destroyed humanity and turned almost everyone insane because they wanted company.
Thank you for posting this video. Years ago, I made something like this by accident, that I would now very much like to recreate.

excellent video, thank you for spending time on it !
very inspiring, hope this will catch on soon.
This is how the blocks were MADE for the pyramids. They weren't hauled or moved or quarried. They were made with geopolymers and poured where they exactly are
I am honored to be the 1k 👍 on this video
what a wonderfull material
something that would be interesting is using a carbon dioxide releasing agent in the geopolymer and a laser system to fuse layer by layer the clay substances so it will puff up like the graphene foam that forms from doing this with Kapton tape, but being left with a solid block of insulative tough clay structure, instead almost like an intumescent clay material, something else I guess I need to add to my list of ongoing concepts, as I am betting it coupled with the passive thermal diode effect could enable cooling or heating passively anywhere while being able to retain this heat or cooled area's effect from that insulation property of a foamed fired clay.
very well presented.
Highly informative, thank you! I'm writing my minor thesis on a topic involving geopolymer composites and I have no idea about anything yet.
Cool. How did it age? I made my bachelor and masters thesis about geopolymers and, yes, there is so little practical and accurate information out there.
@@Advanced_Materials_Publishing I got a credit LOL. I was honestly happy about that because that was a very stressful time in my life. Turns out flyash-based, polyethylene fibre-reinforced geopolymer composites don’t perform well as structural members after being exposed to elevated temperatures (200 - 800 degC).
You got a credit like a credit point? Mission achieved, I'd say 😄
It’s a beautiful technology that I think is older than we realize! Have fun on your thesis, but remember that more than likely no one is going to read it. But if you like what you learn and are proud of your work you will do great!
Nice video, and thank you for putting this out there. But according to the Geopolymer institute, alkali based products are not geopolymers.... However they are still a good building material that should be explored....
thank you sir❤
Interesting idea that, the pyramids being refashioned mine tailings and waste to stable useful form.
so nice
I wonder which geopolymers were used to build the pyramids?
Sir can i develop brake pads using this geopolymer. May i know its properties
I've been doing concrete in Fairbanks for long time so is my buddy
Whats available locally and what works...
Very informative, thank you! Much better than the useless videos put out by the Geopolymer Institute.
Great video, can we have an update?
Hey this is fascinating- i want to cast some sculptures out of geopoylmers in Brooklyn. What would you suggest using? Thinking super cheap and hopefully reuse biproducts like you did. Thanks!
No way, I'm doing the same in London. Just ordered the last of the ingredients. Did you have any success?
Status updates? I'm hoping to do the same in New Jersey...thanks!!!
No mention of sodium Silicate ?
What do you think about using Dessert sand and use it for geo polymer? Because it is an material which is in huge amount.
The blown sand would be surface smooth, it would not be good. You need sharp sand.
@@undernetjack what if you Mix it with plastic?
@@CUBETechie There are videos showing that exact process on youtube, for making tiles and roofing shingles etc.
@@undernetjack a title or link would be amazing
Development and Optimization of Geopolymers Made ... - MDP by A El-Mir · 2022 · Cited by 9 - Desert dune sand has been used as an essential material in the construction industry.....
Thank you for the video! Do you think geopolymers could be used in environments with huge pressure and/or high temperature? E.g drilling for oil and making tunnels for roads?
+BucketOf Hurt Portland cement used in concrete performs better when blended with these co-polymers. Mixing portland cement with a ratio of Fly ash usually results in a concrete with a higher compressive stength.
There are others like Silica fume which is mixed in for water proof and high acid areas like under the sea etc.
Aaron James Thank you very much!
@Renato unREAL and thats why i mentioned silica fume as well.. different applications.
How would you "foam" the geopolymer?
It is easy, as geopolymer paste which is basically flyash added with sodium silicate and sodium hydroxide, this paste has a density of 2,000 kg/m3 and it is above 60mpa in compressive strength, so you add in foam to expand it or reduce the density, ( but not with stone added as the stone aggregate tents to sink to bottom when foam is added ) if you need a foam generator and foaming agent, contact me please. my name is Alex ( www.lcm.my )
@@lightweightconcrete this is awesome ... I have a foam generator and need to try this. Where should I get the materials!???
@@tf1639 USD 3.5 per liter, minimum order 25 liters, but problem is chipping may take a long time,
a liter is to be added with 30 parts water known as Premix Solutiion and expand 10 timew or shoots into or become 10 liter foams.
@@lightweightconcrete hello. I'm confident that I have an ideal foaming agent. I just want to try geopolymer instead of concrete. I don't know how to get the geopolymer raw materials
sir is the production of geopolymer concrete is cost effective than a conventional cooncrete
too complex to be explained in a CZcams short...
say hi to mr google for me...
What is the product that is mentioned at 02:01 ? Flour what??
+Contrastarian Contrastarian Quartz flour. essentially we find gold deposited in Quartz. The Quartz is crushed and processed to extract the Gold. Once complete you are left with alot of Quartz Dust, or as he called it "tailings" aka Quartz flour. I think it takes 4 tonnes of quartz to extract 1 kilo of Gold or some crazy ratio, so you can imagine there is alot of quartz flour around.

Can limestone be made into a molten paste? and then get back into stone?
SOme guy told me geopolymers were a scam. All that because of a video that has a theory about the pyramids being made out of geopolymers.
"release 80% less co2 during production than Portland cement". Can you back this up with some document or report or something?
Fly Ash usually contains heavy metals including lead, chromium and mercury. It also is often laced with arsenic.
Oil and Coal are best used very sparingly. Want to learn about strength? Examine a bird skeleton (an already dead one please) a spider web, etc.
The Carbon Energy companies LOVE to be paid every month or more often (It's why they hate solar and wind). Oil and Coal LOVE their taxpayer funded subsidies and they LOVE when someone makes a video to help them get rid of their toxic waste.
the love wind and solar when their carbon energy is being sold to the companies to manufacture those solar and wind units, since it takes a TON of energy to make virtually all solar tech just to refine the materials, and the only reason it is some what cheap now is due to processor and chip waste silicon that gets reused to make solar cells so most of the expense is done and already paid for by computer enthusiasts LOL. Solar has a very dirty secret, that it may be possible to use tech like we use for geopolymers and silica gels manufacture to make them with far less energy, (and expand our tech options beyond just pure silicon embedded with boron and coated in phosphorus, I mean there are tons more electron donor elements and proton donors as well, to experiment with, so while those two (boron and phosphorus) work well in pure silicon, what would work well in sapphire? (aluminum oxide crystal) that can be made with sodium hydroxide and aluminum to make sodium aluminate so it can be dissolved and mixed with an acid to extract that sodium leaving gelled aluminum oxide, which how it forms is all down to how we dry that water out of the aluminum oxide gel (freeze dry and get sapphire based aerogel better thermal stability at high temps like for glass kilns to retain heat better and save tons of carbon energy when making glass the old way XD) or slow dry maybe even add something to ultra slow it and have stronger pull on the aluminum and oxygen while evaporating out to make nice solid uniform sapphire crystal, say in the shape of a window, or a flask or plasma toroid XD ) so many possibilities springing out of uncovering and exploiting these loop holes in physics XD
@@ThomasAndersonbsf it’s a year layer, and still nobody has read that rambling wall of text.
@@ThomasAndersonbsf - Right up my alley! Material Sciences are the elephant in the room. Yet, most of the media's "look over here" is toward "energy"...
@@samuelluria4744 yep replicator tech is all about knowing how to manipulate materials both to break it down and prep it as well as put it back together how we want too, and not so much about generic transfer of energy. or energy to matter like startrek heads want to believe.
@@ThomasAndersonbsf - Well said. Presumably, the public understanding of the expendable nature of _any_ form of energy, makes it easier to uphold profit margins. The dream of durability is kept far from their eyes, however, as it's hard to charge more for products which rarely wear out.
Where is the flash going now?
This is the technology of the future. Once humanity removes head from bottom, we will stop using metals and soon find even printed circuit boards made from geopolymers,
not geopolymer, it uses activator
Hempcrete + Geopolymer
sodium hydroxide or sodium oxide?
dehydrated sodium hydroxide? is that something worth doing even if it can be done? (I know some stuff once it hydrates like copper sulfate, it can't just be driven off with heat, as it decomposes releasing sulfur oxides and copper oxide powders, so from what I have seen it takes some sort of strong dehydrating substance like zeolites that have to be pulled and dried in an oven then put back in dry and let it adsorb the water components leaving the anhydrous copper sulfate, and seems like sodium oxide would have one heck of a pull to hold onto hydrogen in its hydroxide state, Now I need to go look and see if that info is available, since otherwise I am going to be spending some time trying it out myself XD

Yeah, touch the sodium hydroxide without gloves or a lab coat... smart

Just primitive, the old megalithic structures are made from Iron Ore fused stone by way of induction heating, and your building materials only last you 50 to 100 up to 400 years well our advanced past building would last for thousands of years, as well you could always reheat and reshape the iron ore stone,
Yes, but it takes months to achieve that strength. We don't have the time to use that process anymore. It's all , now, now, now, get it done yesterday, time is money...
Induction heating was most definitely not used by ancient peoples

They used geopolymers back thousands of years ago to build the monolythic structures we see today, so you haven't invented anything new!
if no one gave them info to start with then it is called reinventing, like "no reason to reinvent the wheel, here is info on exactly how to make a wheel" if they don't have that "how to, then it is an invention, and discovery to modern people who did not have the information because it was lost, else we could say aliens somewhere in the vastness of the universe invented virtually everything because like the simpsons they have had far more time before we had a chance to even start, so of course ":simpsons already did it!" lol
I think the more important statement is "ok now that we have this info where do we go from here," I am researching this stuff for both a chance to develop better tooth filling material, that anyone can make once I have a good recipe and plan laid out to put up online, and to make better materials for building a new place in a given location using resources local to the area, to both make it cheaper and better, as well as make it possible to blend in easily into the area, incase it needs to be hidden, considering how many people there has always been that just want to watch the world burn, or destroy something someone else has made. (and starlink and similar tech is coming that will give us the ability to have internet virtually anywhere in the world be it a hidden geopolymere home in the mountains, or a giant closed cell foam plastic island floating out in the ocean, made by collecting all that plastic pollution in the ocean and melting it into a slurry to be squirted out of a giant 3D printer nozzle on a 3D printer floating on pontoon style floats for its base, so cavities for halls and rooms can be printed right into that giant turtle shell looking plastic foam island LOL. (and turn natural resources found in the ocean into resources to sell when propelling near a coast to do trade there. )
All talk and not a single example.
where are you looking that there are no examples? just wondering so I can avoid the location, if it still holds no actual usable and actionable information.
All science and no CZcams expert clickbait BS.
it's hard to understand this video, maybe because very bad english
Good luck with your very bad English
So Egyptians used mine tailings? Makes sense.
