Pyramids Were Built with Concrete Rather Than Rocks, Scientists Claim

The Ancient Egyptians built their great Pyramids by pouring concrete into blocks high on the site rather than hauling up giant stones, according to a new Franco-American study. 

The research, by materials scientists from national institutions, adds fuel to a theory that the pharaohs’ craftsmen had enough skill and materials at hand to cast the two-tonne limestone blocks that dress the Cheops and other Pyramids.

Despite mounting support from scientists, Egyptologists have rejected the concrete claim, first made in the late 1970s by Joseph Davidovits, a French chemist.

    It would be interesting to see a time comparison of cutting and hauling stone to building a mold, pour/packing it, vibrate out the air pockets and let it cure for 5 to 90 days (depending on make up and temps).
    A mold would explain the exacting dimensions better than a stone saw. and they had all the available material right at hand to make stone. I would love to see a selection of unweathered blocks and the shiny sheath stones that used to be on the pyramid. We could compare them and see if the building blocks were cut and polished or molded as the sheathing stones would have to have been cut and would show evidence of being cut and polished.
