Spread the years , the Great Wall still towering , weathered challenges . What is the secret to create enduring strength of that works wonders ?
The Great Wall - the pride of the Chinese people in particular and humanity in general has undergone over the years endure rain or shine . Robust architecture , great that seemed to be made up of extremely rare materials and complicated , but in fact , glutinous rice - special things simple , folk and popular in Asian diet Europe is the main material makes the solid walls of this magnificent , a study results indicate .
Sticky rice is the main reason that a fundamental building mortar used in ancient China has been Vietnam features super . The researchers also discovered that the mortar is still the best material for the renovation of ancient architecture .
Stucco is building a cohesive material , used to fill joints between bricks , stone , or between other types of construction materials . Research by Chinese scientists checklist Zhang and colleagues discovered that the Chinese workers brought ancient glutinous rice mixed with liquid mortar ( mortar sand ) and " the oven" special type of mortar durability , extremely adhesive ideal .

The pride of humanity |
Sticky rice mortar probably was the first mixed mortar world is composed of the inorganic component and organic . This mortar durable than conventional sand lime mortar with very good water resistance . Even experts checklist Zhang also said that this is one of the greatest innovations in the history of mankind . The ancients took advantage of sticky rice mortar to build special tombs , stupas , palaces , of which the architecture still exists to this day . With solid features , a number of ancient architecture and time challenged the mechanical effects of human and natural , viable even after the powerful earthquake .
The study also discovered a substance "secret " called amylopectin . It seems that the main cause of this is mainly made miraculous power of sticky rice mortar at the Great Wall . Amylopectin was found in glutinous rice and other starchy foods other .
Checklist Zhang said: " The analysis , research shows that ancient mortar is a special composite material consisting of inorganic and organic substances . Inorganic component is calcium carbonate here , organic matter body is amylopectin . substance in glutinous rice which is mixed into the mortar more common . Additionally , we also discovered that amylopectin in the mortar which acts as an inhibitor : on the one hand , it suppresses the increase of calcium carbonate crystals , on the other hand , it creates extreme texture sustainable micro , tight . structure makes mortar mixture of inorganic and organic aforementioned features powerful adhesive " .
Which "secret power" help The Great Wall to last?
