New thought on the creation of the great pyramids

I was just discussing at work today with a colleague the topic of the construction of the great pyramids. I posted on the site here last year a bit about new thinking on the process, and today found another article about possible casting work done in the creation of the pyramids.

The widely accepted theory-that the pyramids were crafted of carved-out giant limestone blocks that workers carried up ramps-had not only not been embraced by everyone, but as important had quite a number of holes.

According to the caller, the mysteries had actually been solved by Joseph Davidovits, Director of the Geopolymer Institute in St. Quentin, France, more than two decades ago. Davidovits claimed that the stones of the pyramids were actually made of a very early form of concrete created using a mixture of limestone, clay, lime, and water.

A year and a half later, after extensive scanning electron microscope (SEM) observations and other testing, Barsoum and his research group finally began to draw some conclusions about the pyramids. They found that the tiniest structures within the inner and outer casing stones were indeed consistent with a reconstituted limestone. The cement binding the limestone aggregate was either silicon dioxide (the building block of quartz) or a calcium and magnesium-rich silicate mineral.

. . .

Egyptologists are consistently confronted by unanswered questions: How is it possible that some of the blocks are so perfectly matched that not even a human hair can be inserted between them? Why, despite the existence of millions of tons of stone, carved presumably with copper chisels, has not one copper chisel ever been found on the Giza Plateau?

That still doesn’t tell us how the big blocks that weren’t created on the spot got there and in place. It doesn’t answer all the questions scientists have about the pyramids. But it is a promising step forward in understanding how they were built.
