Davidovits Proposes Geopolymer Pyramid Theory. Joseph Davidovits was a chemist specializing in synthetic mineral materials and industrial binders In the 1970s, he noticed pyramid stones behaved differently from natural limestone under chemical testing He examined a casing stone from the Great Pyramid (the Lauer sample) under a microscope
In the late 1970s, chemist Joseph Davidovits examined casing stones from the Great Pyramid & found telltale signs of man-made concrete: trapped air bubbles, organic fibers, & other anomalies. Natural limestone formed over millions of years wouldn't show these features. Could ancient builders have cast blocks like concrete?
Key Facts
- Joseph Davidovits was a chemist specializing in synthetic mineral materials and industrial binders
- In the 1970s, he noticed pyramid stones behaved differently from natural limestone under chemical testing
- He examined a casing stone from the Great Pyramid (the Lauer sample) under a microscope
- He observed telltale signs of artificial composition: trapped air bubbles, organic fibers, and bits of animal bone and teeth
- These features are characteristic of man-made concrete, not natural limestone formed over millions of years
- The theory proposes blocks were cast in place using three-sided wooden molds connected to finished blocks
