More on the concrete pyramids Tantalising new pyramid theory: they were built from concrete
IT IS a theory that gives indigestion to mainstream archaeologists: some of the immense blocks of Egypt's Great Pyramids might have been cast from synthetic material - the world's first concrete - not carved whole from quarries and hauled into place.

Such an innovation would have saved millions of man-hours of grunting and heaving in building the enigmatic edifices on the Giza Plateau.

Not exactly new though.
