Are Pyramids Made Out of Concrete?

https://www.geopolymer.org/archaeology/pyramids/are-pyramids-made-out-of-concrete-1/[/vc_column_text][vc_column_text]The website reveals how Ancient Egyptians built the pyramids using man-made stones, which look exactly like natural rocks. The limestone blocks were cast in situ, employing an advanced technology that was later lost, leaving a puzzle hidden for thousands of years inside the pyramid stones. This theory undoubtedly shed an amazing new light on what really happened in Egypt in that remote era.
The Pyramids at Giza have more than 5 million blocks of limestone, until now believed to be CARVED stones, new evidences shows they were CAST with agglomerated limestone concrete.
The scientific background, including analysis, formula, stone making, are disclosed in the recently updated book by Prof. Joseph Davidovits Geopolymer Chemistry & Applications, in several chapters, i.e. Chapters 5, 11, 13, 17 and 20.
Paleomagnetism study supports Pyramid geopolymer stone

A recent scientific study published in the renown “Europhysics News“, The Magazine of the European Physical Society, (2012), Vol. 43, number 6, described how paleomagnetism study on several pyramid stones demonstrates the validity of Davidovits’ theory on the artificial nature of Egyptian pyramid stones.
Two scientists, Dr. Igor Túnyi from Geophysical Institute SAS – Bratislava (Slovak Republic) and Ibrahim A. El-hemaly from National Research Institute of Astronomy and Geophysics – Cairo, Egypt, made the following assumption (quote from their scientific paper):
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 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.

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.
