Fig. 8From: Sustainability problems of the Giza pyramidsa Cracking and splitting of backing limestone blocks due to the high compression and overloading and material decay and strength regression, which affected the great Cheops pyramid stability. b The honeycomb weathering (differential erosion) patterns are obvious on the surfaces of limestone blocks. Alveolization develops her as cavities illustrating a combination of honeycombs and alignment following the natural bedding planes of the limestoneBack to article page
