Major results of our paper
 The inner and outer casing stones of the
Great Pyramid are not natural.
 The microstructure is consistent with a
reconstituted limestone where the cementing
phase is either silicon dioxide or a Ca-Mgsilicate.
 The starting materials are believed to be
diatomaceous earth, dolomite and lime.
 In other words, some of the blocks must have
been cast in place.


Diatomaceous earth consists of fossilized remains of diatoms, a type of hard-shelled algae. It is used as a filtration aid, as a mild abrasive, as a mechanical insecticide, as an absorbent for liquids, as cat litter, as an activator in blood clotting studies, and as a component of dynamite. As it is also heat-resistant, it can be used as a thermal insulator.
