I was watching Paul Cooks videos and for some reason the algos sent me here I wonder if it is because he says geopolymer 20 times in most videos.

[@cryptofxalgorithms]

There is ample evidence most of the pyramid blocks were made of geosynthetic concretelike limestone blocks composed of limestone aggregates and old form of cement , Lime and Sodium carbonate. The geosynthetic granites of the pyramids to me would then have been made of an earlier form of Lime composed liquid glass probably from Lime and sand under heat as binders for aggregate granite or other stones.

[@crazyjay6331]

I think they had both advanced machinery and advanced geo polymers, you need machinery to polish blocks afterwards, also there are granite mounds around India that have been carved away, to leave the exquisite temples imbedded within, and lots of examples of blocks being left in mid quarry globally. Also in Egypt there are the remains of a massive granite statue that has flint and quartz veins and would have stood as tall as the Statue of Liberty. Given the toughness of the granite blocks at Giza, you would need machinery to polish or correct any casting mistakes, or you would need machinery to mine it from a mountain, either 🤷‍♂️way you need advanced machinery which is way beyond what is currently claimed, so sit back down u chumps that think u can just shut the book on this ting now, not that you have. Just anyone out there who thinks this is the trump card for advanced machinery, it’s not, we still have the rest of the puzzle to solve and it’s one of those billion piece puzzles that old people buy😂 Also as far as Ik, no one recently has made truly solid granite geo polymer like it is at Giza - if it even is. And yes I’m aware the pyramids are not made of granite although it is featured.

quite simple really. the hard part came with the mathematics and the science to make it all fit.

Usually you wait 24 hours to demould them. Some mixtures need only 4 hours or less. Heating up increases the solidification reaction greatly. 60 to 80 °C for instance, and covered to prevent from drying.

I seem to remember some blocks were geopolymere and some were not. I think maybe the larger ones lower down were geopolymere. Can't remember might be backwards and smaller up top were. You can see some ground level with the bumps on them. Maybe some outer stones were. Still a problem. I've heard ideas about water buyancy to float stones up. Might be the best idea.

They were simply clay/limestone earth that was scooped up from the edges of Lake natron and packed into forms. There is no reason for fossils to be ground up. SEM proves it

[@VenturaIT]

They actually took the fake pyramid blocks to labs and the labs couldn't tell which was fake and which was natural limestone. The fossils aren't ground up because they use loosely bound limestone aggregate, not ground limestone. Watch the videos. Andesite - kzbin.info/www/bejne/qJecon5vhrmfp5I

"6- There are granite blocks that are carved but roughly trimmed. So, your theory is wrong. We have never claimed granite was artificial (another hearsay). Indeed, granite is not carved (they did not have the right tools) but split (a very different skill). You will read below in the extended abstract under the “Religious context” why they used granite, because it represents the southern country. The granite was not carved in a quarry, but simply taken from individual boulders found in great quantities in the Aswan region. The boulders were split to fine dressed faces, leaving a typical rough undressed back. They represent less than 0.1% of the total blocks. Workers had 10 years to install them in the pyramid, and 10 years to carve a unique sarcophagus with whatever technique they have at their disposal. In short, we don’t care! We care about the 99.9% of limestone blocks. For Kheops, one block must be placed every 3 minutes." www.geopolymer.org/faq/faq-for-artificial-stone-supporters/

@@thecure4470 No, you're the one on a tangent. This is a video about the blocks of the pyramid and geopolymers not about something else, just because there is something completely different doesn't mean or prove that they are carved or cast. it doesn't mean anything. Perhaps the box is carved, I haven't seen any xray or electron microscope examination of the box you are talking about. I'd wait to hear a real scientist like Davidovitz comment about it before I make a decision. Problem is that archaeology isn't really a science, it's an "activity" or a "study" but not a pure science. Geopolymer is a science. Nobody really knows what happened in the past, but the best theory is the geopolymer theory and for a theory to come in out of the blue and be able to have all the science support it 100% is impressive. Right now it's the leading theory. That doesn't mean they didn't split natural rock. It doesn't mean they didn't cast granite that looks natural then split it. It doesn't mean anything. There are bowls and containers that are also different kind of geopolymer than just limestone, or the stones in south America, geopolymers can be nearly any type of earthen material.

[@stephenphillips4984]

This idea is totally misconceived. The whole point about the geopolymer theory was to explain in terms of moulding heavy blocks of stone whose structure, size and/or numbers was hard to explain in terms of the technology/tools known to have been possessed by the indigenous people. There is NO evidence of moulding - all the blocks are of DIFFERENT shape and size - precisely what gangs of men would produce who had to remove what was available in quarries. The quarries used either on the Giza plateau to build the pyramids or near the megalithic sites in Peru and Bolivia are well-known and prove from scientific assays that the blocks were hewn from them - their mineralogy proves it. So why on earth would any people MOULD their building blocks when it was simpler to extract them from quarries? The geopolymer theory is useless, disproved by tons of evidence and has no power to explain anything better than conventional explanation coupled with lost high-technologies. The geopolymer theory crept in through the backdoor of popular interest in alternatives to academic views about megalathic monuments. But there was never any need for it! Quite apart from no evidence to support it other than contentious claims made by the Geopolymer Institute, which have been thoroughly debunked by many scientists and which have never been tested by any other laboratory.

The imprints of the bags they poured to stuff in are still there for all to see, it's impossible to chisel stone so the surface looks like burlap.
