Did The Egyptians Pour The Pyramids?
A man by the name of Joseph Davidvovits began to contest this classical theory of pyramid construction in 1979. His ideas and research may force even Egyptologists to revise their thinking about how the pyramids were built. Davidovits suggests that the Egyptians actually used man-made stone that was cast at the pyramid site, where it was needed. The process, he says involved pouring slurry of crushed limestone and special mineral binder into wooden molds. Within a few hours the mixture would harden into material almost indistinguishable from rock. Such a construction method would have taken less time, and required far fewer workers.
In 1984 Davidovits presented his conclusions from a analysis of rock samples from three of the pyramids and two limestone quarries at Turah and Mokhatam, traditionally associated with pyramid building. He found that the pyramids samples contained traces of minerals that were not found in the quarry. Instead, they contained as much as 13 percent of what Davidovits calls a “geopolymeric” binder. In addition, microscope examination of the samples showed that the quarried limestone consisted almost entirely of lightly packed calcite crystals that gave it a uniform density. In contrast, the casting stone was less dense and contained numerous air bubbles. Consequently if the casting stones were natural limestone, and did not match that of the quarries than where did the Egyptians get there stone? There are other clues that suggest that the Egyptians poured the pyramids.
The ingredients deeded for the mineral binder- sodium carbonate, various phosphates, quartz, and Nile silt, were all readily available to the Egyptians. In addition the casting stones had a millimeter thick surface coating that appears to consist entirely of this binder. Davidovits suggests that during setting some of the binder came to the surface to form a “skin”, it was the presence of this obviously man made coating that originally prompted him to look for traces of this material within the rock itself. This idea of manufactured stone helps to explain how the sides of the casting stone were so smooth and straight, maybe to straight for a man to quarry, cut, and shape the stone. This could also explain how the Egyptians were able to get the blocks to fit so well together that a postcard cannot even be inserted in between them. The sides of the previously molded blocks could be used as the walls for making the stone in between them. With this system, and a primitive form of concrete, the Egyptians may have completed pyramid construction within a relatively fast and effortless period of time
