Concrete Silica Fume supplied by Quanzhou Winitoor Industry Co., Ltd. is an amorphous silicon dioxide (SiO2) microsilica powder used as a pozzolanic additive in concrete mixes. The material provides high‑purity microsilica content that significantly enhances density, compressive strength and long‑term durability of concrete. It is particularly valued for marine structures, bridge decks and high‑strength precast elements where performance specifications are stringent.
Typical commercial silica fume contains at least 95 % SiO2 and a specific surface area around 20 000 m² kg⁻¹, both of which drive pozzolanic activity. Moisture content is usually kept below 1 % to preserve reactivity, and bulk density ranges from 0.5 to 0.7 g cm⁻³. Particle size distribution is centred on a median diameter of 0.1‑0.2 µm, allowing the powder to fill voids in the cement matrix. Suppliers commonly ship the product in 20 MT flexible intermediate bulk containers (FIBCs) or 25 kg paper sacks.
Readymix plants, precast manufacturers and infrastructure contractors are the main buyers of this additive. Quanzhou Winitoor Industry offers both bulk and bagged supply, and buyers should confirm the preferred packaging, FOB terms and the letter of credit payment method with the supplier. The company states that its silica fume complies with ISO and SGS quality standards, but exact certification documents should be requested before contract finalisation.

Shipping is arranged on a FOB basis, and the supplier mentions flexible minimum order quantities to suit different project sizes. No additional corporate history, employee numbers or client references are provided in the listing.
Silica fume is a high-performance pozzolanic additive widely used in concrete and shotcrete applications to significantly improve density, compressive strength, and long-term durability including corrosion and chemical resistance. This supplementary cementitious material is particularly valued in marine structures, bridge decks, and high-strength precast concrete where performance specifications are stringent. As a global trade commodity in bulk or bagged form, it is sourced from ferrosilicon and silicon metal production facilities worldwide, with leading suppliers in Norway, the United States, and China, and typically shipped in 20 MT flexible intermediate bulk containers (FIBC) or 25 kg sacks to construction material importers and readymix plants.

Sourcing Concrete Silica Fume from Quanzhou Winitoor Industry Co., Ltd. - China Import Guide
Before placing an order, importers should obtain a recent chemical analysis report that confirms SiO2 purity, specific surface area and moisture content. Request the supplier’s ISO and SGS certificates and verify that the testing laboratory is accredited. It is also advisable to ask for a sample batch to evaluate workability and compatibility with the intended cement type.
Quanzhou Winitoor Industry ships the silica fume on a FOB basis from ports in Fujian, typically using 20 MT FIBCs or 25 kg sacks. Buyers should confirm the estimated loading time, vessel schedule and any port handling fees. Payment is usually made by irrevocable L/C, but the exact terms should be negotiated and documented in the sales contract.
During production, the supplier conducts particle‑size distribution and moisture tests in accordance with standard methods; importers are encouraged to arrange a third‑party inspection at the factory before shipment. The final shipment should be accompanied by a Certificate of Analysis, a Material Safety Data Sheet and the ISO/SGS certificates referenced earlier. Retaining these documents facilitates customs clearance and downstream quality assurance.
