Microsilica powder with 85 to 96 percent silica content is a pozzolanic additive designed for high-performance concrete and shotcrete. Sourced by Quanzhou Winitoor Industry Co., Ltd. from China, this material complies with ASTM C1240 and EN 13263 standards, delivering enhanced density, compressive strength, and durability in infrastructure applications. It is available in densified or undensified forms, tailored for ready mix concrete where improved impact resistance and corrosion protection are critical.
The product features a fine particle size that fills voids in cement matrices, reducing permeability and increasing resistance to chlorides, sulfates, and nitrates. Typical industry use includes concrete tiles, repair mortars, and oil well grouting, where its lightweight properties and high-temperature performance are valued. Microsilica is a standard supplementary cementitious material in modern construction, often replacing 5 to 10 percent of cement by weight without compromising workability.
Importers of this microsilica primarily serve infrastructure projects, precast concrete manufacturers, and refractory producers. Quanzhou Winitoor Industry Co., Ltd. packages the material in 25 kg bags or jumbo sacks for global export, with logistics originating from Fujian. Buyers should confirm bulk density, fineness, and moisture content specifications, as these directly influence concrete mix performance and setting time.

Before ordering, verify the silica content and fineness of the microsilica, as these are critical for concrete performance. Request a certificate of analysis (COA) that includes silica percentage, particle size distribution, and moisture content. Confirm that the material meets ASTM C1240 or EN 13263 standards, as non-compliant batches may compromise structural integrity.
Logistics for microsilica typically involve sea freight from Fujian, with lead times depending on vessel schedules and port congestion. Clarify Incoterms (e.g., FOB or CIF) with Quanzhou Winitoor Industry Co., Ltd., as these define responsibility for shipping costs and insurance. Packaging should be checked for durability, especially for jumbo sacks, which may require additional palletizing for stability.
Quality checks should include on-site testing for bulk density and moisture content upon receipt. For critical projects, arrange third-party inspection at the supplier’s facility to verify compliance with specifications. Documentation such as material safety data sheets (MSDS) and COAs must accompany each shipment, and buyers should ensure these are provided in English for customs clearance.
