The Surprisingly Plausible Theory that the Pyramids were Poured from Ancient Concrete | December 15, 2020 | Today I Found Out

A 3,500-year-old inscription on a stone block found in Egypt is what archaeologists say the oldest weather report of the world. The inscription on a six-foot-tall calcite stone, called the Tempest Stela, describes rain, darkness and "the sky being in storm without cessation, louder than the cries of the masses," according to Nadine Moeller and Robert Ritner at the University of Chicago's Oriental Institute who have translated the 40-line inscription. The stela's text also describes bodies floating down the Nile like "skiffs of papyrus." "This was clearly a major storm, and different from the kinds of heavy rains that Egypt...

Like millions of tourists, from the Ancient Greeks on, the Blairs may have been victims of one of the world's oldest confidence tricks when they walked round the Pyramids on the Prime Minister's holiday trip to Egypt. To the uninitiated eye, the 2.3 million blocks of stones rising to a 146-metre peak on the 4,500-year-old Great Pyramid near Cairo look as solid as pure granite. But French architects and scientists believe they are nothing more than weathered concrete blocks, moulded on the spot, stone by stone and layer by layer, from the ground upwards. The theory, being explored by ...

...using synchrotrons to analyse the synthetic turquoise that was popular during the reign of Pharaoh Akhenaten around 1300BC. Archaeologist Dr Mark Eccleston... says Egyptian 'faience', a fine-glazed quartz ceramic of distinct turquoise colour, was a common material used in items ranging from simple beads to religious artefacts. He says while it was known that larger factories were used to produce the faience, his research has shown less prestigious pieces could also have been produced in ovens in household courtyards... "Large state industries were effectively sub-contracting labour and the household would get something in return, for example more food." ...Eccleston says...

Drexel University researchers are revising the book on the Pyramids of Egypt, the last surviving wonder of the ancient world. The standard hypothesis for their construction speculates that ancient Egyptians carved the blocks out of nearby deposits of natural limestone, using stone age tools, and then floated the stones on barges, and used primitive ramps and levers to wrestle the blocks into place. The fact is, no one knows even to this day how the Pyramids were built. Many of the limestone blocks fit so perfectly that not even a human hair ....

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. The stones, say the historians and archeologists, were all carved from nearby...

Scientists say pyramids could be concrete April 23, 2008 Scientists are taking a new look at Egypt's pyramids to see if some of the blocks could have been made from concrete. Linn W. Hobbs, a materials science professor at Massachusetts Institute of Technology, told The Boston Globe there is a chance ancient Egyptians could have cast the blocks from synthetic material instead of carving them from quarries. Scientists have long believed Romans were the first to use structural concrete. Undergraduates in MIT's Materials in Human Experience class are building a scale-model pyramid made of quarried limestone and blocks cast from...

Riddle Of The Great Pyramids Of Giza: Professor Finds Some Building Blocks Were Concrete In partially solving a mystery that has baffled archeologists for centuries, a Drexel University professor has determined that the Great Pyramids of Giza were constructed with a combination of not only carved stones but the first blocks of limestone-based concrete cast by any civilization.

At MIT, Hobbs and two colleagues teach a course called Materials in Human Experience... The MIT pyramid will contain only about 280 blocks, compared with 2.3 million in the grandest of the Great Pyramids... Hobbs describes himself as "agnostic" on the issue, but believes mainstream archeologists have been too contemptuous of work by other scientists suggesting the possibility of concrete. "The degree of hostility aimed at experimentation is disturbing," he said. "Too many big egos and too many published works may be riding on the idea that every pyramid block was carved, not cast." ...In 2006, research by Michel W....

Egypt's Pyramids Packed With Seashells Jennifer Viegas, Discovery News Fossil-Filled April 25, 2008 -- Many of Egypt's most famous monuments, such as the Sphinx and Cheops, contain hundreds of thousands of marine fossils, most of which are fully intact and preserved in the walls of the structures, according to a new study. The study's authors suggest that the stones that make up the examined monuments at Giza plateau, Fayum and Abydos must have been carved out of natural stone since they reveal what chunks of the sea floor must have looked like over 4,000 years ago, when the buildings were...
