Abstract
The Waseda University team has carried out a conservation work for the layered stone structure on the slope of the Abusir-South hill in 2006 season. The structure was probably erected in the Third Dynasty, which period is known as a time of the realization of stone structure in Ancient Egypt.
Since weathering of the upper surface of the structure was severe and a large number of the blocks appeared to have been flaking, the upper surface of the structure was covered with not only sand but also a kind of mortar mixed with clay, sand, and slaked lime in order to detain sand accumulation. The mortar was stabilized by hammering.
It is expected that above conservation work will prevent further deterioration of the layered stone structure for years to come.
