Silica Fume/microsilica
Silica Fume, also known as microsilica, is a by‑product consisting mainly of silicon dioxide (SiO2) used as a pozzolanic additive in cementitious mixes. Wuhan Newreach Materials Co., Ltd. offers both densified and undensified grades with SiO2 purities of 85 %, 92 % and 95 % as stated in their catalogue. The material is supplied in bulk form suitable for large‑scale concrete production and can be blended directly into mortar or grout. These grades are commonly selected to meet specific performance targets in high‑strength concrete formulations.
The product is available in densified and undensified physical states; densified material has a higher bulk density which reduces transportation volume, while undensified material flows more freely for certain mixing processes. In the global market, typical silica fume bulk densities range from 300 kg m‑3 for undensified to about 600 kg m‑3 for densified forms, and particle sizes are generally centred around 15 µm. Purity levels above 85 % SiO2 are regarded as standard for most structural applications, and moisture content is usually kept below 5 % to preserve reactivity. The supplier indicates that these specifications align with industry expectations for durability and compressive‑strength improvements.
Key buyers include concrete producers, precast manufacturers and firms producing corrosion‑resistant coatings. The material is imported in bulk bags or 25 kg cartons, allowing flexibility in handling and storage at the destination port. Trade terms such as incoterms, payment schedules and minimum order quantities are not disclosed in the listing and should be clarified directly with Wuhan Newreach Materials before placing an order.

Sourcing Silica Fume/microsilica from Wuhan Newreach Materials Co., Ltd. - China Import Guide
Before placing an order, importers should confirm the exact SiO2 grade, physical form and bulk density that will be shipped. Request a recent material test report that includes purity, particle size distribution and moisture content to verify that the product meets the required specifications for the intended concrete mix design.
Logistics considerations include confirming the incoterm (such as FOB Wuhan or CIF Shanghai), expected lead time for production and loading, and the payment terms accepted by Wuhan Newreach Materials. Because the response rate shown is currently zero, it is advisable to establish a clear communication channel, possibly through a phone call or video conference, to avoid delays in finalising the contract.
Quality assurance steps should involve arranging a third‑party inspection at the loading port, checking the bulk density and moisture content against the agreed values, and obtaining the necessary certificates of analysis and conformity. Importers are also encouraged to request a copy of the factory audit report and any relevant ISO or environmental certifications before shipment.
