The pyramids of Egypt have always been fascinated. Archaeologists, architects and Egyptologists from around the world interested in the ingenuity of their construction. Many questions remain unanswered about the methods that have been applied. Some theories advanced over the years.

The secrets of building the pyramids of Egypt

The stone blocks were hauled one by one according to Herodotus.

Methods of construction of the pyramids of Egypt remain a secret to drilling. The size of the pyramids and material content not found in modern construction techniques. Knowing that every pyramid is composed of thousands of stones carved perfectly arranged on each other to the top of each building, and some stone blocks weighing up to 40 tons, it is difficult to imagine that human hands could have produce such masterpieces. Several theories have been advanced, some are based on archaeological findings and other studies on mathematics and physics.

Herodotus’s theory was the basis for all researchers. According to the Greek historian who visited Egypt 450 years BC, the stone blocks were transported from Arabia to the Nile, and then dragged onto the construction site. Using ingenious machines made in wood, each block was raised to its final location. Several machines would thus relayed to the apex of the pyramid. To achieve such a feat, the Egyptians had to solve various problems, especially concerning the means of transport, size of blocks, lever systems, construction time, the number of workers.

Probable or not, theories abound

The size of the boulders, which should be noted, not all the same size but perfectly joined together without gaps, puzzles researchers. Indeed, at that time, the hardest material copper was too soft for cutting granite blocks. The elevation system of each pyramid turmoil also specialists. Ludwig Borchardt and Jean-Philippe Lauer assume that the workers used a ramp and then fired adobe blocks on sledges. Other researchers also speak of helical ramp, side ramps, ramp committed … but these ramps were then to be cleared, which would have been a daunting task for most. Moreover, according to Herodotus, 20 years would have been enough to build the pyramid of Cheops, which rises to 146 meters. After some calculations, it would have taken 10,000 men every three months to raise 32 blocks of 2.5 tons per hour.

If all these theories seem unlikely somewhere, Joseph Davidovits ahead of his side a more plausible theory based on archaeological evidence: the Egyptians would have disintegrated limestone and have blended with other natural binders, they would then reagglomerate all in molds to form blocks. This theory solves the problems of transport and those of size. Moreover, J. Davidovits has been demonstrated in full scale feasibility of this technique. Recent research also showed that the ratio between the rate of calcium, silicon and magnesium in the stone blocks of the pyramids is not found on any type of natural rock.
