There is a guy on you tube that built his own miniature Stonehenge made of cement. He used the known ancient techniques, by himself, to move blocks that weighed upwards of 10 tons.
Cement is a fine grayish powder. How did he get it to stay put when the wind blew?
How about moving 1000 ton or 1200 ton stones like the ones found at the temple of jupiter in Baalbek, Lebanon? Has anyone figured that out yet?
