Premium Silica Fume from a Trusted Chinese Manufacturer
Henan Superior Abrasives (HSA) is a professional manufacturer and global supplier of premium silica fume (microsilica). With years of production and export experience, we provide high-quality silica fume for customers in the construction, refractory, oil & gas, and precast concrete industries.
Our silica fume is manufactured under strict quality control to ensure stable chemical composition, consistent particle size, and reliable performance in demanding applications.
What Is Silica Fume?
Silica fume, also known as microsilica, is an ultrafine pozzolanic material collected during the production of silicon metal and ferrosilicon alloys.
Due to its extremely fine particle size and high amorphous silicon dioxide (SiO₂) content, silica fume significantly improves the strength, density, durability, and chemical resistance of concrete.
Typical applications include:
- High-strength concrete
- Ultra-high-performance concrete (UHPC)
- Bridge and highway construction
- Marine structures
- Industrial flooring
- Shotcrete
- Oil well cementing
- Refractory castables
