  "summary": "A new study examining Roman concrete from Hadrian’s Villa in Tivoli, Italy, may provide a clue to how the ancient Egyptians constructed the Great Pyramid of Giza. Researchers from several universities found that Roman concrete not only resists decay but actually grows stronger over centuries through a self-healing process. This phenomenon, driven by carbonation and mineral growth, could potentially explain how the pyramid's massive stone blocks were constructed and maintained for over 4,500 years, suggesting that the builders may have used a calcium-rich concrete-like material that evolved over time.",
