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.

Super High-rise Buildings

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, with 2,395 buildings above 150 meters, 823 buildings above 200 meters, og 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, Silica røg, granulated blast furnace slag and other mineral admixtures can be added. Such as Silica røg , 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, seepage resistance, corrosion, impact resistance and wear resistance, with water retention, prevent segregation, water secretion, significantly reduce the role of concrete pumping resistance.

Silica Fume Other Applications

• Ildfaste materialer. Silica dampe er almindeligt anvendt i støbning, sintrede, og smeltede ildfaste materialer. F.eks, det kan bruges i høj ydeevne, høj kvalitet, og lav-cement ildfaste støbegods og præfabrikerede dele, luftgennemtrængelige mursten, storstilede jerngrave og øser, og mere.
• Mørtel og beton. Silica-røg kan også bruges til havnekajer, højhuse, jernbanebroer, reservoirdæmninger, betonbelægning, og mere.
• Beskyttende belægninger. Nano-silica sol tjener som et aktivt materiale til brandbeskyttelse, miljøbeskyttelse, og antikorrosiv belægning.
• Væg og dekorative materialer. Silica-røg kan også bruges til termisk isoleringsmørtel, polymermørtel, og som grænseflademiddel til vægisolering.
• Kitt. Microsilica kan bruges i spartelpulver til udvendig og indvendig vægisolering.
• Fyldning og forstærkning. Det bruges også som fyld- og forstærkningsmaterialer i harpiks, gummi, maling, umættet polyester, og mere.
• Tilsætningsstoffer. Endelig, silica dampe er almindeligt anvendt som et tilsætningsstof i andre aktive områder.
