Skyscrapers are landmarks in urban centers, not only promoting land use and economic development, but also a modern transformation of success and wealth. The completion of super-tall buildings represents the image of the city on the one hand, and promotes the development of related architectural, and economic fields on the other.
超高层建筑
Since entering the 21st century, skyscrapers, the symbols of modern cities, have been rising at an astonishing rate all over China, refreshing the city skyline time and again. According to statistics, China has 40% of the world’s super-tall buildings, 和 2,395 buildings above 150 meters, 823 buildings above 200 meters, 和 95 buildings above 300 meters, all three indicators ranking first in the world. Micro-silica powder, as a concrete additive, is widely used in the application of super-high rise buildings because of its own characteristics.
Silica Fume Features
Super high-rise buildings have high requirements for concrete, in order to improve the performance of high-strength concrete and reduce the amount of cement to reduce the heat of hydration, a certain amount of fly ash, 微硅粉, granulated blast furnace slag and other mineral admixtures can be added. Such as 微硅粉 , can fill the pores between the cement particles, while generating gel with hydration products, and alkaline material magnesium oxide reaction to generate gel. Can significantly improve the compressive, folding, 抗渗性, 腐蚀, impact resistance and wear resistance, with water retention, prevent segregation, water secretion, significantly reduce the role of concrete pumping resistance.
