Post # 41 reference (Concrete Pyramids) is mostly about a book touting concrete pyramids by Morris and Davidovits.
This is one silly assertion made at the web site referenced at # 41, “If laborers were cutting the stones, where is the scrap from the trimming, bad blocks, and the blocks that fractured or were damaged in transit? There are not any[11]. With concrete, the rocks were beaten to a powder, hauled to the site, burned, mixed, and cast. Everything is consumed and can be reused by powdering and heating it again.”
Not “if” since the quarries are still in existence today where laborers removed the cut stone.
“Burned”? With what as fuel? “Beaten to a powder”? By what means? What kind of “rocks”? Only one kind is used to make concrete by heating, not “burning”.
Utter rubbish! Why not claim space aliens with mysterious tractor beams?
Nut job logic says that if they don’t understand something then it’s a mystery that no one understands. That leaves them free to come up with some whacko theory that ignores all the obvious evidence and allows them to say no one can disprove what they have failed to demonstrate in the first instance. Just make and keep making the same silly assertions as though they were fact and maybe gather the whole mess into a book.
no need to beat anything to powder. The formers were mainly filled up with stone, and then some sort of liquid was poured in. That’s the only possible way it could have been done. The amount of work which would have been involved in carving all of those stones is totally prohibitive; it could not have been done.
That reminds me of the time I found myself traveling in Egypt with a tour group who thought they were all reincarnated ancient Egyptians, who in turn had been reincarnated Atlanteans. One of them remarked that there wasn't any evidence of the stonecutting the Egyptians were supposed to have done. And I looked around me at a landscape that was basically nothing but sand and rocks of various sizes, and thought, "Huh? What are you looking for?"
On another occasion we were looking at a long flight of steps carved in the side of a cliff, leading up to what we were told was a crypt. One person said, "I'd hate to have been a pallbearer in those days," to which another replied, perfectly seriously, "Oh, it wasn't a problem because they had the secret of levitation." And I just thought, "WHAT DID THEY NEED THE STEPS FOR THEN???" Sometimes people just don't think things through.
