Xi'an University of Architecture and Technology has developed a kind of high ductility concrete, which is a fiber reinforced composite material based on cement and quartz sand.
It has high strength, high toughness, high crack resistance and high durability. The tensile deformation is more than 200 times that of ordinary concrete, and the impact resistance and collapse resistance of the reinforced brick wall can be improved by more than 10 times.
According to reports, it is used to reinforce buildings, when the construction thickness reaches about 1.5 centimeters, even if it reaches a rare earthquake of 9 degrees, the house will not collapse.
At present, this technology has been popularized and applied throughout the country, mainly involving the reinforcement of school buildings, the renovation of farm houses, the protection of cultural relics and the renovation of historic buildings.
