It’s not an engineering publication
The article is sparse in specifics or references, simply saying ramps means nothing.
There is in fact very little available on any methods to move massive blocks.

Generally it is a sense of power and/control that is otherwise lacking day-to-day, stemming from also not understanding what considerate is due to childhood trauma, combined with difficulty to control impulses.
Correct, concrete doesn’t contain calcium carbonate.
By weight, this mixture, once set, would be mostly calcium carbonate and calcium hydroxide. The hydroxide becomes carbonate over time as part of the lime cycle, hardening as it does.
This “stone” is as dense and hard as natural limestone.
Mud bricks are not stones blocks. Not comparable.
Again. You will not find an engineer who will support your theory in the context of the Giza pyramids.
To have any object be moved to a vertical position of 45 storeys above the ground, your pulley system will need to be even higher, and supported by some structure.
You will struggle to find an engineer worth his or her salt agreeing with you..
It is obvious that the builders took advantage...
You say pullies and counter weights but you clearly don’t understand how it works.
How many of those cultures are before the wheel was invented?
How many monuments were 45 storeys high?
Large, single, alabaster blocks makes sense since they would have been used for carving sculptures, but would not be related to pyramid building.
Some of the stones weigh as much as a fully loaded semi-trailer, did the Egyptians even have rope with enough tensile strength to move such an object...
You are wrong obviously. It is a construction material that anyone can Google to learn about.
Do you read your sources?
There is nothing about concrete, only soft and hard limestone.
The soft limestone isn’t soft, it just has a high clay content, which is separated when soaked in water...
You keep insisting on concrete but where I the evidence for the use of ANY concrete in ancient times?
Reconstituted limestone with slaked quicklime, which also will naturally turn into limestone, makes the most sense.
There is no reason why the Egyptians couldn’t use reconstituted limestone...
Once again you don’t provide the full text of the source.
In spite of the location of their discovery nearly 150 miles southeast of Giza, the relics do not contain any information about activities related to the pyramid construction at Wadi el-Jarf. “The surprising presence of these documents...
Is it?
Reads like it is about a “mighty” man from Edom who was able to slay his enemies, even though the city was destroyed.
It sounds like he meets with the Jews who’s city/temple has been destroyed, and he praises God nevertheless, asking that he and his people be “remembered” again...
