Davidovits experiments with pouring 15 tons of pyramid limestones in northern France (St. Quentin), with each block of 1-2 tons, showed how it only takes 2-4 hours until they could remove the wooden mold to pour the next block on the side to it. If you see how many blocks you need for each of the about 100 layers of the Great Pyramid, there is enough time to let one layer harden enough to be able to continue on the next layer above. At maximum a few days in the much warmer Egyptian climate compared to northern France.
