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.Silica Fume used in floor construction site

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.microsilica-concrete

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.Silica Fume Concrete

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.Silica fume as high-strength admixture in concrete

9. Shotcrete

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.Silica fumes in concrete
