6. Applications
Silica fume is widely used in concrete field: High-performance project, such as bridge, airport, hydropowder station, seawall, railway projects.
1) Enhance the mechanical properties of concrete.
High strength and early strength has been used in substructures of high-performance concrete.
2) Improve the durability of concrete:
Significant improvements can be seen in the permeability resistance, abrasion resistance, anti-corrosion against chlorideion and anti-freezing of concrete.
3) Enhance consructability.
Improve shotconrete, increase easily strength, control temperature contractors can take advantage of the properties of silica fume concrete to expedite projects or to achieve properties that might otherwise be impossible to achieve.
4) For mortar and concrete in : high-rise buildings, the harbor docks, dams, water culvert, railway public bridges, subways, tunnels, airport runways, concrete pavement and the coal mine tunnel shotcrete reinforcement.
