The workers build the Great Wall in the Ming Dynasty era, around 600 years ago by mixing flour with chalk, as a standard mixture of adhesive material, said Dr. Zhang Bingjian. Zhang Bingjian.
Glutinous mixture of bricks tied so tightly to many plants grow easly and made effect to wall became strong. However, rejection occurs widely in southern China against construction of the wall because the Emperor Ming asked harvest rice in the south for food and as a mixture of cement workers.
'The mix of ancient cement glue that consist of a special kind of mixture of organic and inorganic,' said Dr. Zhang, an expert in chemistry from Zhejiang University, Hangzhou city, east China, as reported by the Telegraph.
'Organic component, amylopectin, is derived from glutinous rice porridge that is added to the mixture of cement,' he added.
'Inorganic component is calcium carbonate and organic components are derived from glutinous rice amylopectin. Amylopectin is helping to create dense microstructure, making the Great Wall is more stable and have greater mechanical strength, 'according to the report in the journal of the American Chemical Society.
Zhang said, the use of sticky rice, staple food of East Asia, is one of the biggest technical innovation at the time, which helps various tomb, pagodas, and the wall at the time of the Ming Dynasty from the blow of the weather, earthquakes and other natural disasters.[]
