Is this sarcasm? The theory is entirely logical. Concrete is a sand/gravel slurry that is held rigid until a hydrating binder cures. One can even make free-standing continuous-cast concrete objects with minimal forming, simply by slip-casting. Silos are made that way.
Funny you should mention "slip-cast" or, as we say in the biz, "slip-form."
Not two weeks ago I was pumping concrete at the new Holnam Cement plant near Harleyville, SC.
They are building some really BIG silos there. Slip forms--one continuous pour, no cold joints. No small task. A dedicated miniature concrete batch plant on site mixing concrete 24 hrs a day for weeks at a time.
Kinda cool, but the mining aspect of the operation is not pretty.
Yeah, the Egyptians formed the blocks of the pyramids in situ, similar to what was done on Easter Island. And how did those Incas REALLY get their stones to fit so perfectly?
Whatever they did with granite, it works better than concrete, which is much weaker than most folks suppose. If I had the patent...
