1. Low heat concrete
Replacing cement with silica fume, the strength remains unchanged and the temperature of the concrete changes, which is the most effective way to obtain low-heat concrete while maintaining the same early strength.
2. Waterproof concrete
Due to its low permeability, in some relatively humid places, micro silica fume is an indispensable waterproof material for some underground structures, such as underground parking lots.
3. Corrosion resistant concrete
Micro silica fume is suitable for some structures exposed to seawater and deicing salts, such as ports, docks, local groundwater and onshore buildings with chlorides in the soil and air.
4. High-strength concrete
Micro-silica fume offers great economic benefits to developers, such as reducing the thickness of columns and walls in high-rise buildings and improving structural layout. In the process of construction, silica fume concrete is also easy to pump.
5. Self-compacting concrete
Due to its very high surface area, silica fume concrete is sticky, preventing bleeding and separation, which is extremely important for self-compacting concrete, which is fluid and easy to separate.
6. Sulfate resistant concrete
Micro silica fume concrete has low penetration and chemical resistance, and can provide better sulfate corrosion resistance than other cement adhesives.
7. Chemical resistance
Silica fume concrete is widely used in structural parts exposed to a range of harsh chemicals, making it extremely valuable in industry and agriculture.
8. Wear resistance
Micro silica fume concrete is extremely wear-resistant, which can save a lot of money and time and improve efficiency in the construction of ground and pavement. It is also resistant to hydraulic abrasion and is suitable for spillways of dams.
Whether it is dry or wet production, micro-silica fume used in shotcrete can reduce springback, increase thickness, and increase the scour resistance of offshore construction. When used with fibers, it eliminates mesh and reduces cracks.
