Sorry, I thought this was to do with ancient Egyptian stone being cast, not a worldwide thing. The limestone in Egypt is nummulitic, which would not be the case if the stone were concrete (it would have to be pulverised to be concrete, leaving no fissil traces). I believe Davidovits also said that natural limestone and geopolymer limestone was very difficult to tell apart, begging the question of how he could tell. And I repeat, there are several texts talking about stone being cut and hauled, and not a single mention of any casting of stone in molds. And several large scale quarries from the north to the south of Egypt. There was even the suggestion that because the evidence was so great that the stone was natural, that *only* a certain amount were cast, the rest being naturally carved....which also begs the question of why bother?

So they would break up perfectly good limestone to a fine powder, take out all the nummilites, just to chuck them back in when making the concrete, giving the impression of perfectly good limestone? And then despite it being cast in molds,they would used tools to recarve the geopolymer (you can see chisel marks on almost all stone in the various sites in Egypt).
Why bother? What question does casting the stone answer?
