The pyramids are constructed from concrete

The pyramid cast stone hypothesis

Please first read the introductory article: Why the construction methods of ancient megalithic structures are better kept secret.

The largest pyramid is that of Khufu, standing at 147 meters high and constructed with around 2.3 million blocks, each weighing between 2.5 and 15 tons. The prevailing belief is that the entire pyramids were constructed by tens of thousands of laborers who carved the stone blocks. Even if this is true, questions remain about how the 15-ton stone blocks were repeatedly lifted to carve them precisely to fit accurately against the adjacent stones.

Various hypotheses exist; some claim involvement of extraterrestrial beings. None of these hypotheses seemed remotely plausible to me. Subsequently, I discovered that the pyramids could be constructed with geopolymer cast stone. Everything fell into place after that.

It is important to know that the pyramids contain two types of stones: smaller irregular stones and precisely fitting stones, which are sometimes enormous. The smaller irregular stones are, as the archaeologists claime, were indeed carved out of the rock and moved manually. However, this does not apply to the precisely fitting stones.

Several scientists have discovered that the precisely fitting stones were not carved but cast in a liquid state and then hardened, similar to concrete. Although the geopolymer hypothesis has been unequivocally proven, it is ignored by the established order of archaeologists. However, the dismissal of proven facts by the scientific establishment has occurred many times in the past. For instance, with Einstein's theory of relativity, which was initially not believed. But at some point, the established order could no longer ignore it.

In this article, I want to make clear to everyone how the pyramids were actually built. It is very easy to demonstrate; you only need to observe closely, use common sense, and avoid bias.

Problems with the quarried stones hypothesis

It is true that the Egyptians were capable of quarrying and transporting enormous blocks of limestone and granite from the rocks. Evidence of this can be found in ancient quarries that sometimes still contain partially quarried stones. A famous example is the unfinished obelisk of Aswan. Based on this, we can conclude that using quarried stone blocks of enormous size in the construction of the pyramids was indeed feasible.

There are, however, insurmountable problems with this hypothesis:

  • Many stone blocks have irregular shapes but fit precisely against adjacent stones. This implies that they must have been precisely carved to within 1/10-millimeter accuracy, exactly mirroring the adjacent stones. Aside from being a pointless endeavor, this seems practically impossible, especially when using bronze chisels. Furthermore, why would the Egyptians invest so much effort when the inner stones aren't even visible?
  • From a logistical standpoint, it seems practically impossible to accomplish this work for millions of stones within a limited timeframe.
  • How were these stones, some weighing up to 15 tons, transported? Why would the Egyptians go through so much trouble when they could simply have halved the stones?

The precisely fitting stones of the pyramids were built with concrete

But fortunately, there is no need to puzzle over these questions. As mentioned earlier, many stones of the pyramids are made from cast stone. This fact has been proven and can also be easily observed, as I will explain now.

Once you understand that casting stones in ancient times, similar to modern concrete, was possible, the cast stone construction method makes a lot of sense. You can clearly see that the stones were poured to each other in liquid form. It can be observed that the concrete has occasionally flowed beneath the formwork:

The scientific evidence of Joseph Davidovits and Michel Barsoum

However, there is also a scientific proof, which was provided by among other Joseph Davidovits and Michel Barsoum: the composition of the stones does not correspond to naturally occurring limestone. So, it is impossible that they were carved out of the rocks. Joseph Davidovits is a specialist in the field of geopolymer. He has been researching the construction of the pyramids since 1974. For a more in-depth exploration, consider reading his book: Why the Pharaohs Built the Pyramids with Fake Stones.

Some evidence supporting the pyramid cast stone hypothesis

  • Through casting, the stones naturally fit together seamlessly. However, it's worth noting that due to earthquakes, many stones are no longer as neatly aligned as they were originally.
  • Calculations indicate that using casting techniques made it feasible to build the pyramids within a 20-year time frame.
  • Paleomagnetic research suggests that the stones in the pyramids are not natural rocks.
  • The density at the bottom of the stone blocks is greater than that at the top.
  • The hieroglyphs on the Famine Stele describe the minerals used in the casting mixture.
