Super Concrete or How to Build a Pyramid

I ran across this story on wired.com today about super concrete and the US Military. Among the story ideas, including bombs bouncing off bunkers and other fantastical applications like mugs that don't shatter, the writer mentioned a French scientist, Joseph Davidovits of the Geopolymer Institute, who claims that the Ejyptian pyramids may have been built with a re-agglomerated stone rather than massive blocks.

An intriguing idea that solves a lot of heretofore baffling logistical challenges.


The applications for construction of major projects, even today, are enormous. Quick runways, immovable and nearly indestructible foundations... other ideas?
