Description
AC-Microsil-Si9+ is a high-purity, amorphous silica dioxide (SiO₂) powder designed for high-performance cementitious and ceramic systems. Composed of sub-micron particles (avg. 0.15 microns), it acts as a powerful pozzolan, optimizing particle packing and chemical reactivity. It fully complies with ASTM C 1240 and AASHTO M307 standards.
Primary Applications
- High-Performance Concrete: Critical for bridge decks, parking ramps, and high-durability marine structures.
- Refractory & Industrial: Used in blast furnace troughs, ladle linings, and sliding gates in the steel and foundry industries.
- Cement & Ceramics: Ideal for lining rotary kilns, preheater systems, and high-temperature kiln furniture.
- Specialized Grouting: Enhances the density of high-quality mortars and precision grouts.
Key Advantages
- Superior Packing Efficiency: The wide particle size distribution fills microscopic voids, significantly increasing concrete density.
- Enhanced Strength: Boosts both early and ultimate compressive strength through intense pozzolanic reactivity.
- Extreme Durability: Drastically reduces permeability, providing a robust defense against chemical attack and environmental wear.
- System Synergy: Works seamlessly with plasticizers to produce ultra-flowable, high-strength mixtures.
