Try using diatomaceous earth instead of quarts powder(large surface area substance).. Also try calcium silicate in the mix. In geopolymers one needs a calcium and potassium or sodium source together with diatomaceous earth IMO for best results. Also there are a class of geopolymer that needs a little heat to set, these are interesting to experiment with as well. Finally there are catalysts that make the bonding better like a little iron pyrites for example.
Hey Michael, thanks for your suggestions. The experiments with diatomaceous earth we performed in the university didn't work and then I rather persuade other projects. I have a hugh list of cuing projects on which I want to work first. Do you have some literature on the pyrite catalyst or so? Best, Pat
@@Advanced_Materials_Publishing My experience is with higher temp setting geopolymers, using less reactive stuff, not water glass, so adding a iron pyrite catalyst to a mixture of cream of tartar (potassium source) diatomaceous earth(silica source), wollastonite (calcium silicate and calcium source) and kaolin clay and water, produced a nice pink geopolymer(pink granite compositing type) that was nice and hard after being cooked in an oven to remove the water and fired in a wood fire. The iron pyrite catalyst was just an experiment I read somewhere it can be used as a catalyst but I forget where.
@@michaelpudney No prob. Still good input of yours. Kind of why I'm doing this 👍🙂 The German name for cream of tartar is by the way "Weinstein" which litterally means "wine stone" or "stone of wine". Have a good one! Pat
kaolin clay can be found just about anywhere in the world its nothing special to make kaolin clay just have to heat it up 1500 degrees to remove the water bound to it then mix it with sodium silicate some lime and and aggregate thats it
Thank you for sharing your video and experiments. The foamed ceramic got my attention especially, so it will be a working out of ratios. But it looks like something could come together quickly. It's good work!
I appreciate your videos. I've been very interested in this. Have you experimented with organic indigo dye pigment and palygorskite clay? I hear the indigo dye gets trapped in the needle-like tubes of the clay and has great electrical properties of some sort. It would be great to see you experiment with that some day.
Hello! Thank you for your comment and suggestion; I really appreciate it, as I'm always searching for interesting topics to create videos about. So far, I haven't worked with many pigments, but it's something I've been considering from time to time. I've made a note of it so I don't forget amidst all my ideas. Which type of indigo are you referring to? The synthetic one, the natural one, or the green leaf powder? Have a good one! Best, Patrick
I'd like to see GPC used or demonstrated in poured foundations. I am building a home in 2 years (maybe less) and I want to use GPC. Something other than 3D printed homes which seem rinky-dink.
pre-etch your river sand in a lye solution to remove staining and increase bonding to the aggregate. can you give details on the phos acid geopolymer please? I would like to reproduce.
Hello there! Good idea with the etching! Thank you. I have published three (plus two) recipes in the formulations book. The Kindle edition is quite affordable. However, I should mention that phosphorus is likely to become more and more expensive. In the end, if we were to use phosphorus-based geopolymers (P-GPs) on a large scale, poorer countries might face difficulties. If we were to buy a lot, it would increase the prices, potentially making fertilizers less accessible for these nations. Best, Pat
Hey, good idea! I'm working on more content but its a lot of work. I hope in the future I have more time or resources for publishing content and books. But its really a good idea!
@@Advanced_Materials_Publishing Testing compressive strength would be a rather essential aspect of publishing a book on structural material recipe formulations ?
@@heartobefelt What truly fascinated me back then wasn't just analyzing data in a table, but actually witnessing and feeling how a stone could be formed from a bit of dirt and liquids in just one day. For those genuinely interested in making geopolymer concrete, it's essential to experiment with their own mixes and raw materials. In the end, this video is a brief, freely shared concept and not a promotional advertisement for a material suitable for building a house.
Yeah, many mineral materials look the same. For most people all the stones for instance look exactly the same. In my upcoming book there will be an detailed explanation whats the difference between plaster of Paris and GPs 👍
What’s happened in the case put these samples in water? I made some in the cold weather and some more water besides the quantity weight as formula because of too dry to mix ,they couldn’t harder ,they were still fluid,when I got them to heat,they were harder but absorbed water and broken .
Hello! The geopolymer samples are resistant to boiling water, as my first and go-to test is the boiling water test. This involves leaving the samples in boiling water for over 30 minutes. If the samples do not disaggregate, it's quite likely that the geopolymerization reaction was successful. A sample only bound by hardened waterglass would fall apart. I've made a note to create a video about this boiling water test-it's easy to do and provides valuable insights. Thanks for the idea! Best, Patrick
it can be done has been done but its heavily suppressed knowledge because of big business lobbying to keep itout of search engines and out of public knowledge
Yes, it can. But pay attention when you buy it. I know of people (Amazon comments) who got problems with the police or FEDs because Al powder is very reactive and one can make explo*ives from it.
No, it is metal powders like aluminium. So actually the one I used is another one which I keep a secrete. But aluminium works. Have you used boric acid in such a way?
Hey Rob (I assume), marble dust is CaCO3, a sort of lime. That can be used but wont harden/cure by itself, so only as aggregates. But the properties seem to be good, when used as filler. Fine material on the other hand can cause problems in concretes and that like. It love to give some GP material to a stone carver and learn from him if this works well for him, but haven't done it yet. Best, Pat
I did one with Ca(OH)2 which works but takes quite long until it cures. That is like the Romans did their cement. With sodium carbonate I wanted to do some experiments since you can buy it in the drugstore. In general the waterglass-NaOH "activators" are the most promising ones. Anyways, I cant tell right now how it alters the characteristics. Cheers. Pat
Hello! Commercial GPs are mostly made from slag and fly ash. MK-based are too expensive at the moment. They all claim that they want to save the world but in reality is all about the price (which is ok). On the other hand MK-based can reach a higher strength more easily, so to speak. So building purposes it is fly ash and slag and for decorative purposed or cold-curing ceramics, it is MK. But the industry oftertimes try to hide what the really do... :) Best, Patrick
@@Advanced_Materials_Publishing Australia had massive quantities of Fly Ash that they couldnt give away , but after i enquired about sourcing it the cement suppliers panicked and locked up the source to protect OPC ....
I love the look of your geopolymers especially the one with the foaming agent. Is there any chane you can post the english one to a UK address or French address?
He G_lions! Thanks for your question. But I have one myself: What do you mean with "post the english one"? My question is just post what and post where, which platform? Best, Pat
@@Advanced_Materials_Publishing Hey, I was asking about your book and an English translation as Amazon uk wouldn't post to the uk. I used the link you gave in the other video and It worked. I now have a English version of your book! Thanks!
Hello Patrick. I am Wilmar Andrade, I am Colombian but I have lived in Quebec, Canada for 25 years. I am very interested in buying your books but I do not speak German or English, only Spanish and French.... Taking advantage of AI I can translate documents with great precision. I am very interested in your books and I would like to buy them but it would take me a long time to translate them.... I would like to know if you have those books in .PDF and I can pay for them via PayPal or eTransfer or other means that you have. PDF would save me all the time in the world to translate it into Spanish. Please let me know... I want to compare some of your data with. Those of Joseph Davidovits
Hello Wilmar, Thank you for your interest in my work. Unfortunately, all rights to my books currently belong to the publisher, and I am not permitted to distribute PDFs or other unauthorized copies. Amazon has a strict policy against copyright infringement, and authors who violate these rules risk having their accounts terminated and being permanently banned from the platform. They enforce these rules strictly because copyright violations were rampant in the past. While I cannot provide PDFs directly, you may be able to convert the ebook version into a PDF format for personal use. However, I'm not certain if this would be considered a permitted use under Amazon's terms of service, so I would advise caution. If you're interested in accessing my work, I would suggest purchasing the ebook version of the book you're interested in, such as the formulations book which is available at a lower price point. I recommend the English versions, as those are the most up-to-date editions. My plan is to publish translations into other languages once I've completed this current book project, which I hope to achieve by early 2028. I hope you have a wonderful day. Best regards, Patrick
@@Advanced_Materials_Publishing Hi Patrick. Thank you for answering me, I already bought your books electronically and I already translated the book that is in German... it looks very similar to the English version... I have them in PDF and they are for personal use only. I believe they are very interesting, I congratulate you on your research work. My intention is to create an artistic movement here in Edmonton, Canada, where we can use an alternative to concrete. I have a series of artistic pieces that I personally want to make in geopolymers.... and I will thank you because you are the reason for this work, thank you Bro and have a good day. Wilmar
@@wilmarandrade7839 Hey there! Thanks for the kind words, I appreciate it. Artistic movement sounds really cool! If you want to use more geopolymers in your projects, I'd suggest taking some time to experiment. You could mix up a bunch of different batches and use those little plastic sample holders with lids from Amazon. They're like 0.1 liters in size. Make like 20 different mixes, one for each sample holder, and keep them all at around 68°F (20°C). Then, over the next few days, just poke them with something pointy to see if they've cured. Generally, a geopolymer that hardens within the first 24 hours is a good one. The ones that take longer are usually lower quality. But curing times can vary based on the exact mix and conditions. Feel free to hit me up with questions. I don't check social media every day, so it might take me a couple of days to get back to you. But I'm happy to help out where I can. Keep up the good work!
Hey MarekkuCake, kind of. I think if then, they used limestones as aggregates which naturally contain kaolinite in this area and along with naturally accouring soda, maybe more ingrediences, they made the stones. If you are interestet do the following: Watch or observe walls made from synthetic rocks like fired bricks and others made of stacked natuirally rocks. What to you you thinks if you compare? :) Best, Patz
@@Advanced_Materials_Publishing Stones in pyramids or Inca structures seem to be melted or plastic. There no space in between them. But they are stones. It would be logical if there are indeed geo polymers. Softened stone molded and then solidified.
@@marekkucak6581 Yeah, it's pretty likely they used some kind of liquid stuff that hardened up later. I'm thinking it was an early version of concrete because we know for sure ancient folks had these kinds of materials. If you've got the right ingredients, it's not that hard to make. Take the Pantheon and Colosseum in Rome - they're scientifically provable made of similar stuff. And we know the Egyptians and Romans bumped into each other, so they might've swapped some building tricks... I've read about modern concrete workers checking out the pyramids. A bunch of them say it's pretty obvious to them that some parts were poured or packed down, not just stacked up with big stones. I think people love this story of the super villan pharaos with their thousends of slaves... Have a good one! Pat
