X-Ray Analysis and X-Ray
Diffraction of Casing Stones from
the Pryramids of Egypt, and the Limestone of the Associated
by Joseph Davidovits
published in Science in Egyptology, Proceedings of the Science
in Egyptology Symposia, Manchester, U.K., pp. 511-520, 1984.
The hypothesis that the limestone that constitutes the major
pyramids of the Old Kingdom of Egypt is man-made stone, is
discussed. Samples from six different sites at the traditionally
associated quarries of Turah and Mokattam have been studied
using thin-section, chemical X-Ray analysis and X-Ray
diffraction. The results were compared with pyramid casing
stones of Cheops, Teti and Seneferu. The quarry samples are pure
limestone consisting of 96-99% Calcite, 0.5-2.5% Quartz, and
very small amount of dolomite, gypsum and iron-alumino-silicate.
On the other hand the Cheops and Teti casing stones are
limestone consisting of: calcite 85-90% and a high amount of
special minerals such as Opal CT, hydroxy-apatite, a
silico-aluminate, which are not found in the quarries. The
pyramid casing stones are light in density and contain numerous
trapped air bubbles, unlike the quarry samples which are
uniformly dense. If the casing stones were natural limestone,
quarries different from those traditionally associated with the
pyramid sites must be found, but where? X-Ray diffraction of a
red casing stone coating is the first proof to demonstrate the
fact that a complicated man-made geopolymeric system was
produced in Egypt 4,700 years ago.

Prof. Joseph Davidovits, Frédéric
Second Revised Edition ©2000
Professor Joseph Davidovits proposes a
stunning theory of pyramid construction that is based on
scientific, historical, and linguistic studies. The theory
claims that the Egyptian pyramids were constructed using
agglomerated stone (limestone cast like concrete), rather
than carved and dragged blocks of natural limestone.
More than 45,000 copies of the first edition
of "The Pyramids: An Enigma Solved" were sold
from 1988 to 1995, and it is now out of print since 1995.
The book has been revised and edited with
several new chapters, new facts, and new astounding
discoveries. It adds up to 54% of new material. In
particular, the book attempts to demolish the myths and
mysteries of how the pyramids and other remarkable
"stone" objects were created so long ago.
This revised edition is only available on
CD-ROM as an electronic book in Adobe Acrobat PDF format.
It is a 427 pages book with 155 high quality
illustrations, fully printable, Mac, PC, and Unix
compatible. This book is only available in English.
