After the 2008 Wenchuan earthquake, China revised the “code for seismic design of buildings”, which put forward higher requirements for building seismic. Is it possible to have a curved concrete to resist earthquakes? Don’t tell me, someone did it. On the evening of October 9, “bendable concrete” developed by Professor Deng Mingke’s team of School of civil engineering of Xi’an University of architecture and technology appeared in CCTV-2 “entrepreneurial heroes”. < / P > < p > according to the introduction, this kind of “bendable” high ductility concrete has the characteristics of high strength, high toughness and high crack resistance. Adding special fiber with high strength and toughness into the material, the tensile deformation can reach more than 200 times of that of ordinary concrete, and the brick wall strengthened with it can increase the impact resistance and collapse resistance by more than 10 times, which can be used in dangerous building reinforcement and other scenes. < / P > < p > according to the introduction, this kind of material is mainly used in the reinforcement of masonry buildings, which can be widely used in the reconstruction of old residential areas. Deng Mingke’s team is also making basic technical reserves for expanding more application fields. < / P > < p > not only that, the construction of this material is also very convenient, only need to spread a layer of 10 to 20 mm high ductility concrete on the wall surface, can play a reinforcement effect. After a large number of experiments and practical engineering verification, the construction period can be shortened by 70%, and the cost can be saved by 30% at most. < / P > < p > it is worth mentioning that in the program, Deng Mingke gave a 2.5% equity transfer ratio, hoping to raise 10 million yuan, and actually obtained 11 million yuan of intended financing on site, which also means that the market valuation of the project is as high as 440 million yuan.
