You mean 97% local quarry stone or 100%? What's your error probability, the 5% default? Because the 3% geopolymer binder is overlooked by most geologists as Davidovits could empirically prove by sending his one lab-made geopolymer t

Yes. Do you see how the joints have the same air-gap through their irregular shape? The shape of one block at the joint follows exactly the neighbor block at a fixed distance. That's explained by the shrinking over time during completing the curing process. It w

Davidovits experiments with pouring 15 tons of pyramid limestones in northern France (St. Quentin), with each block of 1-2 tons, showed how it only takes 2-4 hours until they cou

That's explained by the experiments done by Davidovits. Those seashells (nummulites) are part of the gravel-like natural limestone scraped from the quarry. As the natural material is kept in that gravel state and not grinded to sand, the sheashells easily make it into

Not powder. Take a look at Davidovits famous video with his Egyptian-style dressed colleagues building a collection of 15 tons of pyramid limestone. The limestone they use is soft and can be scraped by hand or simple woode

I’m well aware of the percussion-theorists’ emotional reaction about this research using contemporary material analysis methods directly looking at what is there.

As an engineer I see it this way: Until an actual wall is build out of three-dimensionally irregular hewn blocks without air gap in the mortar-free joints, I just consider the method as proven which actually could produce that. And that was demonstrated in the famous 2006 video by Davidovits, who created full size geopolymer pyramid limestone blocks which hardened within a few hours, even includi

QuoteIn this post, I review the idea that monumental architecture in Egypt or elsewhere was created by pouring concrete into forms to make stones. From powdered stone.
Since Joseph Davidovits first proposed the notion as early as 1988, various proponents of fringe archaeology like to claim that the monumental architecture of cultures around the globe was created through the use of geopolymer.

It isn’t very often that a theory comes along that one single piece of evidence, one tiny little detail, can destroy the entire thesis.
But here is one of them.
In a nutshell, the author asserts that the pyramids were built centuries earlier over many generations for purposes unknown. This single sentence sums up what the author wishes were true, so that he could proceed with his basele

Once again we see someone proposing a theory about what could be, rather than looking at cultural evidence to document a theory about what should be.
There’s nothing like pulling from completely different chapters of The Histories and mashing them together as if they were written in the same paragraph. And then asserting the theory solves problems for which we have no evidence of their existen
