In it, material scientists claim new chemical evidence of concrete in the higher levels of the pyramids.

There is some interesting information there.

A zeolitic cementitious material, called "geopolymer" by Davidovits, was neither observed by light microscopy nor detected by XRD, DTA, SEM, EDXA, or chemical analysis in the sample examined. Neither was an aggregate-cement fabric observed. Seepage of "geopolymeric concrete" into the open joints between almost all underlying pyramid blocks is obviously nonexistent. Shapes and sizes of pyramid and temple blocks seem too diverse to have been cast in molds.

These analyses are performed in the present study, and it is concluded thatthis sample is a natural limestone that was quarried locally in the Eocene Mokattam Formation. There is no evidence of the special textures and zeolite cement that must exist if the sample is concrete.

Several samples of pyramids from Giza were obtained. The samples were analysed by scanning electron microscopy, electron diffraction by X-rays, powder X-ray diffraction, inductively coupled plasmography, Fourier-transform infrared spectroscopy and other techniques. Some scientists who have recently studied the pyramids have suggested that the pyramids werepoured into place, stone by stone. The prevailing theory among Egyptologists is, of course, that the pyramids were built from blocks of natural stone. All of the results obtained during this study directly support the concept that the pyramids are made of limestone and are not cementitious in nature.
