It appears that the folks over at the Geopolymer institute really nailed it. For many years so called "experts" have either been lying or just naive.. And that sent thousands down the rabbit hole. Including myself. But the explanation is the most rational.
It's concrete.
How did they do it? The same way we do it today.
Concrete is made up of aggregate, water, and a binder that we call cement. As soon as the Egyptians had a rudimentary cement made of calcium carbonate which is obtained from the soft limestone quarry or from sea shells, plus clay, they could then add their aggregate in the form of small pieces of limestone that they could chip off with a stone axe and the silt/sand and water from the Nile River. The first pyramids were small but as the cement techniques and formula was improved they moved on to creating forms in place, and then pouring the concrete mix into the forms.. Just think of or watch a video on how the slab for a house is constructed. It took many years to do this starting of course from the ground level, letting it cure and dry, then advancing to the next level of the Pyramid. The experts kept telling us that the Pyramid blocks were solid stone, but the reality is different... The blocks of stone are actually made from small stones packed together with a cement made from the same stones....
