Sacsayhuamán features intricate polygonal stonework. A controversial hypothesis proposes Inca blocks may have been cast from geopolymer materials rather than carved, though this theory remains disputed among researchers. Alternative interpretations suggest traditional carving techniques explain the precision, with quarries showing stones in various stages of production. The geopolymer theory remains a minority view.

Key facts
- Hypothesis that Inca polygonal blocks were cast from geopolymer materials rather than carved from solid stone
- Geopolymers are artificial stone created by mixing silica/alumina-rich mineral powders with alkaline solutions, hardening at low temperatures
- Blocks shaped while in semi-wet plastic state, pressed into final positions adjacent to previously formed blocks
- Seamless joints achieved through material deformation and pressure rather than precise carving
- Curved interfaces between blocks indicate soft material compression rather than flat stone-to-stone contact
- Scoop marks on stone surfaces described as evidence of material removal while still in semi-plastic state
- Similar scoop marks observed at Aswan Quarry (Egypt), Stonehenge (England), Domus de Janas (Sardinia), and other megalithic sites globally
