The CSA Expansive Agent offered by Frankie Fu is a cement additive manufactured in China. It consists of calcium sulfoaluminate clinker blended with natural anhydrite, delivering controlled expansion during cement hydration. The product displays a specific surface area between 200 and 400 m2/kg and a specific gravity ranging from 2.8 to 3.0, as listed in the supplier data. It carries the model designation “Expansive Agent” and is supplied with a one‑year warranty and online technical support.
Production follows ISO 9001:2000 quality management and ISO 14001:1996 environmental management systems, ensuring repeatable performance. In practice, the additive is mixed with ordinary cement at typical dosages of 5 - 10 % by weight to achieve early‑stage expansion and reduced drying shrinkage. Buyers usually receive the material in 25 kg paper bags or as loose bulk packed in 20 ton containers, with a typical moisture content below 0.5 %. The particle size distribution commonly lies between 10 and 30 µm, which supports uniform dispersion in concrete mixes.
The agent is widely used in self‑stressing concrete, pipe manufacturing, and crack‑resistant structural applications, making it a key input for producers of expansive cement, grout and shotcrete. Primary customers include ready‑mix concrete plants, infrastructure contractors and manufacturers of precast concrete elements. Trade is normally arranged on bulk or bag shipments; buyers should confirm the appropriate HS classification for cement additives and request a formal quotation for quantities and Incoterms. As the supplier does not publish minimum order quantities or lead times, interested importers should contact Frankie Fu directly to negotiate bulk pricing and delivery schedules.

Before placing an order, importers should verify that the CSA Expansive Agent meets the ISO 9001:2000 and ISO 14001:1996 certifications claimed by Frankie Fu, and request a recent test report showing specific surface area and moisture content. It is also advisable to obtain a material safety data sheet and confirm that the product is classified under the correct HS code for cement additives in the destination country.
Shipping is typically arranged either in 25 kg paper bags or as loose bulk in 20 ton containers, so buyers must decide which format aligns with their handling facilities. The supplier does not publish lead‑time or minimum order quantity, therefore the buyer should ask Frankie Fu to confirm the expected production schedule and preferred Incoterms such as FOB Tangshan or CIF Shanghai. Payment terms are not disclosed in the listing and should be negotiated, with common options including T/T against a commercial invoice or a letter of credit.
Upon arrival, a third‑party inspection can verify the specific surface area (200‑400 m2/kg) and specific gravity (2.8‑3.0) against the supplier’s test report. Importers should also check moisture content and ensure the packaging is intact and dry before unloading. Requesting the original ISO certificates, a certificate of analysis and a compliance statement with local cement additive regulations will help confirm that the material meets the required performance standards.
