Traditional assumption: Great Pyramid contains 2.3 million blocks of cut limestone, each weighing ~3 tons Alternative theory: Large proportion of pyramid core is rubble (undressed stone of varying sizes) bound with gypsum mortar Evidence from Hemiunu's mastaba (G4000) at Giza shows outer casing of fine limestone with inner core of irregular limestone blocks and rubble
New research challenges the classic view of the Great Pyramid. The traditional assumption: 2.3 million cut limestone blocks, each weighing around 2.5 tons. But evidence suggests much of the core may be rubble bound with mortar.
Key facts:
- Traditional assumption: Great Pyramid contains 2.3 million blocks of cut limestone, averaging 2.5 tons each
- Alternative theory: Large proportion of pyramid core is rubble (undressed stone of varying sizes) bound with gypsum mortar
- Evidence from Hemiunu's mastaba (G4000) at Giza shows outer casing of fine limestone with inner core of irregular limestone blocks and rubble
- Almoon's Tunnel analysis reveals alternating pattern of rubble and dressed masonry blocks
- Estimate: approximately 25% of Great Pyramid's core may be rubble rather than precision-cut blocks

- Estimate: approximately 25% of Great Pyramid's core may be rubble rather than precision-cut blocks
- Similar construction method documented in Old Kingdom mastabas and 12th Dynasty pyramids (Senusret I pyramid)
- Evidence of sand and rubble fill discovered beneath Queen's Chamber and horizontal passageway
- Outer core blocks vary significantly in size, many smaller than assumed 3-ton average
- Architect Hemiunu (grandson of Sneferu, nephew of Khufu) credited with pyramid design; held titles of vizier and chief justice
- Using rubble construction would reduce quarrying, processing, and placement time while maintaining structural integrity
