OT: GeoPolymers... Super Ancient Concrete built the Pyramids ?

[cbelt3]

This is so amazingly cool

"The story of geopolymers is worthy of a Dan Brown novel, with an unlikely cast including a maverick French scientist, a secretive caste of ancient stone masons and the U.S. Air Force Research Laboratory. Along the way, the mystery of the pyramids gets solved, but it might just end with American bombs bouncing off impervious bunkers"

I met of a guy that went to Italy to research ancient concrete "secrets." 50 years later, two demolition businesses went broke trying to take down the concrete building he put up.

I guess those demolition businesses were experts in taking down house made of wood

Regular commercial demolition companies. The second company knew about the first one and I believe they had recently taken down an overpass with a significant amount of concrete. They beat on it with the biggest hand held jackhammers they had for a couple of days, then a jackhammer on a bobcat.

Not to worry. You just need a bomb that makes a big bang. :-)
