Specification of High Purity Silica Fume Concrete Admixture for Ultra High Performance Concrete UHPC
High Purity Silica Fume Concrete Admixture for Ultra-High Performance Concrete (UHPC)
Pangkalahatang-ideya ng Produkto
This admixture is a high purity silica fume specifically created for ultra-high performance concrete (UHPC). It is an extremely great powder made from silicon metal or ferrosilicon manufacturing. The material has a high surface and strong pozzolanic task. It reacts with calcium hydroxide in cement to form added calcium silicate hydrate (C-S-H), which strengthens the concrete.
Mga Pangunahing Tampok
Severe Purity: Includes over 95% SiO two with extremely low levels of carbon, chloride, and alkali. This makes sure stable efficiency and long-term toughness.
Great Bit Dimension: Average bit dimension is around 0.1 sa 0.2 microns– patungkol sa 100 times smaller sized than normal cement bits. This fills small spaces in between concrete grains and makes the mix denser.
Enhanced Toughness: Assists UHPC reach compressive toughness above 150 MPa. It likewise boosts tensile and flexural strength.
Low Permeability: Lowers water and chloride ion infiltration. This protects steel reinforcement from corrosion and expands service life.
Workability Control: Made use of together with high-range water reducers, it preserves excellent circulation without hemorrhaging or partition.
Teknikal na Pagtutukoy
– SiO two content: ≥ 95%.
– Loss on ignition: ≤ 3.0%.
– Materyal na klorido: ≤ 0.02%.
– Particular surface area: 15– 30 m ²/ g (by wager).
– Bulk density: 200– 300 kg/m ³.
– Lilim: Light grey to off-white.
Advised Use
Isama 8% sa 12% by weight of cementitious products in UHPC blends. Always make use of with a high-performance superplasticizer to maintain workability. Mix thoroughly to ensure also circulation. Shop in a completely dry place away from wetness. Gamitin sa loob 12 buwan ng pagmamanupaktura para sa pinakamagagandang resulta.

Applications of High Purity Silica Fume Concrete Admixture for Ultra High Performance Concrete UHPC
Applications of High Pureness Silica Fume in Ultra-High Performance Concrete
Why Silica Fume Matters in UHPC
Ultra-high efficiency concrete (UHPC) requires really strong and thick product to work well. High pureness silica fume is an essential part of this mix. It fills up little gaps between cement fragments. This makes the concrete much tighter and stronger.
Silica fume additionally aids the concrete last much longer. It blocks water, asin, and other unsafe points from getting in. That suggests much less splitting and much less damages in time. Frameworks constructed with UHPC remain risk-free and strong for several years.
Kung Saan Ito Ginagamit
Home builders use UHPC with high purity silica fume in position that need leading performance. Think of bridges, mga lagusan, and tall structures. These projects face hefty tons, harsh climate, or consistent stress. UHPC provides the strength they require.
It’s also typical out of commission work. Old concrete can be fixed with slim layers of UHPC. The silica fume aids it stick well and match the initial surface area. This saves money and time compared to complete replacements.
In precast components, like panels or beam of lights, UHPC enables thinner designs without shedding strength. That cuts weight and delivery costs. Manufacturing facilities like it since the mix moves smoothly however establishes quickly and hard.
What Makes High Pureness Important
Not all silica fume functions the same. High purity implies less pollutants like carbon or dampness. That results in much better reactions with cement. The outcome is much more constant high quality and greater stamina.
Making use of clean, fine silica fume also enhances how the mix looks. Surface areas come out smooth and uniform– vital for visible components of structures or art items made from concrete.
Service providers and designers select high purity silica fume since it delivers what UHPC promises: severe durability, stamina, and reliability in real-world use.

5 FAQs of High Purity Silica Fume Concrete Admixture for Ultra High Performance Concrete UHPC
Frequently Asked Questions About High Purity Silica Fume for UHPC
What is high purity silica fume?
High purity silica fume is a very fine powder made from silicon metal or ferrosilicon production. It contains over 92% silicon dioxide (SiO₂). The particles are much smaller than cement grains. This helps fill tiny gaps in concrete and makes the mix denser.
Why use silica fume in Ultra-High Performance Concrete (UHPC)?
Silica fume boosts strength and durability in UHPC. It reacts with calcium hydroxide in cement to form more binding compounds. This reaction reduces pores and blocks water paths. Bilang resulta, UHPC becomes stronger, less permeable, and more resistant to chemicals and weather.
How does silica fume affect workability?
Silica fume can make fresh concrete stiffer because of its fine particles. To keep good flow, you often need to add superplasticizers. With the right mix design, UHPC stays workable while gaining high early strength and long-term performance.
Is all silica fume the same?
Hindi. Quality varies by source and processing method. High purity silica fume has low carbon content and consistent particle size. Impurities like unburned carbon can reduce performance. Always choose a product tested for UHPC use to ensure reliability.
How should silica fume be stored and handled?
Store silica fume in dry, sealed containers. Moisture causes clumping and lowers effectiveness. Use proper dust control during handling—wear masks and eye protection. Silica fume is safe when managed correctly but can irritate if inhaled as fine dust.
