The Ancient Egyptian pyramids of Giza, specially the greatest one built by Cheops is the first and most famous one of the seven world wonders. The greatest pyramid of Cheops is the first, oldes and hugest pyramid built by man in Egypt and all over the world. It has been built more than 5000 years ago by the great Egyptian pharoh Cheops within 20 years.
The workers were from all over Egypt and counted up to be more than 120 thousands men between 18 and 40 years of age. It is stands still as a most wonderful amazing of the world as a proof of advanced management, technical, medical and massive work - long term project.
The stones used to build the pyramid were prought from Granite quaries at Aswan about 900 Kilometers south of its location, carries on huge boats traveling down the nile to the nearest river harbour about 5 kilometers from its location, the travelling to its place on glidres over rollers. The smallest stone weighs about 2000 kilograms used to make the highest part of the pyramid, while the largest one weighs about 9000 kilograms, used to make the ceiling of the pharoh burying room with one piece of stone. they had used an amazing very efficient method to do so which is a vaccum pocket on both mating surfaces of every stone.
The Ancient Egyptian builders used for that great building of man are 1,400,000 For that great pyramid and the other quite two smaller ones of Cheops`s incistors: Shefrin and Menkaoraa, the smart ancient Egyptians had no glues, cements or welding methods sifficient enough to keep that huge amount of stones to keep them adjoint together for as long time as mother earth itself would last.
They did not use any cementing material. They used vaccum, the most efficeient powerful and simple method that can confront ever lasting time, massive pressure and annually weeather stresses. At the middle of each mating silk-polished face of a stone they made agrove or a wide and shroud cavity, brush it heavily with flamble oile and burn it while closing up the distance between the mating surface untill they coincide while oil is burning on. So the oil consumed air in the groove to burn, reducing the pressure withen, so much that the greater atmospheric pressure forces the stones together, in such a strong satable and sustained way that allow them to last along the history and guaranteed to keep them like that for no one knows how long.
