Research by Dr.Michel Barsoum and students turn sheds new light about how the ancient pyramids of Giza were built.  Traditional theories state that the Great Pyramids of Giza were built because of enormous amounts of manual labor to haul large chunks of quarried stone across the desert and up ramps. To many researchers, this theory seems not only beyond imagination but also beyond plausibility. Some researchers have rejected the traditional theory all together and instead postulate that the stones making up the pyramids were cast using an early form of cement known as geopolymer.

However, research by Dr.Michel Barsoum and students suggests both theories are correct to some degree. Read more about these theories, concrete and more in the article featured on Medium.
