Lately, we're fascinated by the new discoveries and theories surrounding the construction of Egypt's pyramids. These ancient structures continue to reveal secrets as our understanding of the engineering and materials construction grows. As you may have read here recently, at least one engineer is challenging the commonly held notion of just how the pyramids were built. And now, some researchers suggest that the Egyptians used both man-made cast block along with with limestone block quarried and hauled to the site in the way our traditional explanation proposes.

As originally published on the Watershed Materials blog, Michel Barsoum, professor of materials science at Drexel University, believes that only the exterior casing blocks and the blocks at the higher levels of the pyramids were cast geopolymer blocks. This article goes to state that as predicted, new theories that suggest that even a small portion of the stones in the Pyramids at Giza were man-made blocks formed from an early form of concrete have erupted into a firestorm of resistance and vitriol, most notably from those with the most to lose when an established theory is pulled apart. As much as Barsoum assumed that solid materials analysis could indisputably prove how some of the pyramid’s block were made, the debate still rages on. You can read the entire article here. It's definitely worth your time.
