Egyptian Pyramid blocks = an artificial re-agglomerated limestone concrete?

I heard about this concept years ago. Never again heard about it, but it is amazing. Not sure if there is any new news about it, if they guy still researchs it, if there are things not accounted by this method, etc.

I AGREE

(remembered about this when reading the egyptian drill holes thread, that's why I posted this thread)



edit:

from their website, most news, as well as the video, seems to be from 2006

however, they have a 2013 article which they claim reinforce their hypothesis

apparently, a research investigated a theory about the geopolymer hypothesis, that the blocks magnetic moments would be parallel if made in situ

Quote:

Our paleomagnetic investigation of the two great Egyptian pyramids, Kufu and Khafre, is based on the assumption that if the blocks were made in situ by the geopolymer concrete technique described above, then their magnetic moments would all have been parallel, oriented approximately in the north-south direction. However, if the pyramids were constructed from blocks transported from the nearby quarries, having been rotated randomly during transport and construction, then the directions of their magnetic moments would be oriented randomly

the conclusion seems to say that the in SITU technique may have been used, but natural stone blocks would also have been used NECESSARILY

Quote:

The aim of paleomagnetic investigation of the rock material of the great Egyptian pyramids, Khufu and Khafre, was to find out the directions of the magnetic polarization vectors of their building blocks. This is one of the possible ways to verify the hypothesis according to which the blocks were produced in situ by a concrete technique. The analysis of a limited set of paleomagnetic samples provided the following results. The paleodirections of three sampling locations (2 from Khafre and 1 from Khufu pyramid) exhibit the common north-south orientation, suggesting that they may have been produced in situ by a concrete technique. The block from one sampling location of the Khafre pyramid is of natural limestone and evidently comes from the adjacent quarry. It is likely that the block from one sampling position of the Khufu pyramid comes also from the same quarry. Finally, we conclude that even if the geopolymer concrete technique was used, the pyramids were constructed from a mixture of natural and artificial limestone blocks.

the hypothesis author however does not disputes that. It seems he always claimed it and provides a quote from his book

Quote:

In his book “Why the Pharaohs built the Pyramids with Fake Stones“, Professor Davidovits has clearly shown the location of the natural limestone blocks and terraces (see essentially the Circuit of the Pyramid Plateau at Giza, Egypt, pages 233-262). For example, we know that in the pyramid of Khafre, more than a quarter of the volume of the pyramid is natural stone, namely the terraces carved in the inclined limestone plateau and which constitute the first 5 layers of the pyramid. The book is available at the Geopolymer SHOP and www.amazon.com
