Finnally, some answers to very old questions; gotta love that material sciences stuff.....lots of bandwidth being applied to the field lots of news pending.

Solving the Mysteries of the Pyramids
Drexel Materials Professor Uses Scientific Research to Prove the Use of Early Lime-Based Cement in Pyramids

Dr. Michel Barsoum

Professor Michel Barsoum, Distinguished Professor in the Department of Materials Science and Engineering at Drexel University, and colleagues have found scientific evidence that parts of the Great Pyramids of Giza were built using an early form of concrete, debunking an age old myth that they were built using only cut limestone blocks.

The results of his study have been published in the December issue of The Journal of the American Ceramic Society (“Microstructural Evidence of Reconstituted Limestone Blocks in the Great Pyramids of Egypt,” by M. W. Barsoum, A. Ganguly, G. Hug).

Although this discovery does not solve all of the construction mysteries of the pyramids, the impact of these findings has great potential for developing countries and for the construction industry. The basic raw materials used for constructing these “geopolymers,” as this early form of concrete has been dubbed, can be found virtually any where in the world. Replicating this method of construction would not only be cost effective and long lasting, but would also produce less carbon dioxide than the process used for creating Portland Cement, the current building material of choice.
