2008 m. Nr. Priedas Geomechanical study of building materials of the Hawara pyramid (Fayoum, Egypt)
The contemporary environment in which the monument stone element has managed to exist is essentially determined by climate, industry, geochemistry and sometimes by biospheric agents. In practice, their effects cannot be readily separated. They are a delicate and complex interplay of many factors in practically every case. Nevertheless, these weathering factors may be considered separately, and most important of them are insolation or solar radiation, causing failure through thermal expansion and contraction; moisture leading to fracturing, crumbling and discoloration, exfoliation and finally to deterioration.
