The great Pyramid of Giza is one of the seven wonders of the ancient world that is still remained intact for many generations. It is an interesting structure to discuss because of how long it is standing through everyday forces, such as wind force and any disasters. Most structures in our age need maintenance in a yearly basis to maintain its life span and longevity. The Materials used on the structure plays a big role in deciding the life span of any structure in the world.
The Secret Formula of Longevity
The secret of longevity that we see on the Great Pyramid of Giza is a sign that there a formula to build a structure to withstand forces and has a long life of hundreds to thousands of years. In my opinion, the materials used on the structure can be the reason to the long life span of structures in the ancient world. Currently we are using Concrete as the main source of material in structures around the world like schools, houses and factories. The minimum life of concrete building is about 20 years and the maximum is about 100 years. Discovering new creative ways or finding a new materiel to build a structure may double or triple the current estimate for buildings around the world. As engineering evolve to find the secret of long life span structure, but as for now the secret is still unknown.
