Отв: Цемент в пирамидах Пользователь: АнТюр (IP-адрес скрыт) Дата: 29, January, 2011 16:22 //////Figure 47 is an excellent example of the use of mortar fill in the third pyramid. The lower block, on which the tape rests, has been only crudely finished. The bottom surface of the upper block, on the other hand, is quite flat. The mortar fill varies in thickness from about 8.5 to over 12 cm. Certainly, there was no attempt in this case to use careful fitting to avoid the pressure points that can cause structural failure.
The flat lower surface of the upper block appears to be a universal characteristic of the irregular blocks in the third pyramid. The need for the flat lower surfaces is simply explained by supposing that the blocks were moved on rollers for part of their route from the quarry to the pyramid. Rollers require a minimum standard of flatness for the bottom surfaces of the blocks. The large amount, of mortar and other debris used for fill in the Chephren and Mycerinus pyramids, coupled with the flat-bottomed rocks, suggests another aspect of the construction technique. Irregular tops on the construction blocks make a very poor surface for rolling the next layer of blocks into place. If a layer is first filled with mortar and other debris, however, the top can then be watered and smoothed to provide a good surface for placing the next layer of blocks.///// Electromagnetic Sounder Experiments at the Pyramids of Giza.

Цемент в пирамидах есть. Причем, его применяли не для сцепления верхнего и нижнего блоков между собой, но для выравнивания поверхности нижнего блока перед укладкой верхнего. Таким же успехом могли отливать блоки нужных размеров. |
