Part 7/9:
The Secrets Behind Longevity
What really sets the Great Wall apart from other structures is the resilience of its mortar, a blend of inorganic materials and a unique organic component. Through meticulous examination, researchers unveiled that sticky rice was incorporated into the mortar mix. The starch from the rice significantly enhances the binding properties, ultimately allowing for a structure that grows stronger over time—unlike conventional cement that deteriorates.
Moreover, every element of the Wall was engineered with careful consideration of the environmental conditions. Built using layers that allowed for both strength and flexibility, the Great Wall has successfully endured the ravages of time and nature, standing tall against forces like wind, war, and humidity.
