Workers could extract massive blocks close to the construction zone, reducing the need for heavy hauling over long distances. Material Primary Source Primary Use Limestone Giza Plateau Core structure and lower courses Granite Aswan King’s Chamber and sarcophagus Limestone Tura Outer casing stones Mortar Local gypsum and lime Bed joints and infill.
Pyramid of Giza Materials Level Bedding and Core Construction Insights
Transportation relied on Nile barges during the annual flood, when water levels rose close to the quarry sites. This strategic use of local material ensured a stable supply chain even when transportation routes faced disruptions.
These additives would have enhanced the mortar’s durability and resistance to moisture, contributing to the structure’s longevity in the harsh desert environment. Most of this elegant casing was removed over centuries for building projects in Cairo, revealing the rougher core beneath.
Pyramid of Giza Materials Level Bedding and Mortar Binding Techniques
Workers likely used copper chisels, dolerite pounding stones, and wooden wedges soaked in water to fracture massive blocks. Mortar and Binding Materials Although the pyramid blocks fit together with impressive precision, a mortar-like substance was still used to fill gaps and create a level bedding surface.
