Applications
Microsilica solutions for diverse industrial needs
Concrete
Microsilica significantly improves the properties of concrete by filling voids between cement particles and reacting with calcium hydroxide to form additional C-S-H gel, resulting in denser, stronger, and more durable concrete.
Key Benefits
- Increases compressive strength by 30-50%
- Reduces permeability and water absorption
- Improves resistance to chloride and sulfate attack
- Enhances pumpability and finishability
- Reduces bleeding and segregation
Specific Applications
Cement
Adding microsilica to cement production improves the cement's performance characteristics, including higher early and final strength, reduced porosity, and enhanced chemical resistance.
Key Benefits
- Increases cement strength at all ages
- Reduces porosity and improves density
- Enhances sulfate and acid resistance
- Allows for lower clinker factor, reducing CO2 emissions
Specific Applications
Refractory
Microsilica is essential in refractory formulations, providing improved flowability for castables, reduced water demand, and enhanced high-temperature performance through the formation of ceramic bonds.
Key Benefits
- Improves flowability of refractory castables
