Fly Ash Class F
Sepra Exim Pvt.ltd., based in Hyderabad, Telangana, supplies Class F fly ash produced from the combustion of bituminous and anthracite coals. The material is an aluminosilicate pozzolan that complies with ASTM C618 Class F specifications and contains a higher loss on ignition than Class C ash. Its low calcium content and high silica and alumina levels make it suitable for concrete durability improvements.
In the cement industry, Class F fly ash typically shows alumina contents of 25‑35 %, silica of 45‑55 % and calcium oxide below 10 %. The loss on ignition usually ranges between 5‑10 % and the median particle size is around 45 µm, providing the fineness required for effective pozzolanic reaction. Suppliers often ship the ash in bulk bags of 25 kg or as bulk cargo, which aligns with standard handling practices for large‑scale concrete projects.
The ash is commonly used by ready‑mix concrete producers, precast manufacturers and infrastructure contractors who replace 20‑30 % of Portland cement with the additive to gain higher late‑age strength and reduced permeability. Buyers should confirm the exact bulk density, typical moisture content below 5 % and any required certifications before placing an order. Trade terms, minimum order quantities and lead times are negotiated directly with Sepra Exim and are not disclosed in the listing.

Sourcing Fly Ash Class F from Sepra Exim Pvt.ltd. - India Import Guide
Before placing an order, request a recent Mill Test Report and a Certificate of Analysis that detail the chemical composition, LOI and particle size distribution. Verify that the ash complies with ASTM C618 Class F and that any required certifications, such as ISO 9001, are available. Sampling a small batch for on‑site testing can further confirm suitability for your concrete mix design.
Logistics for bulk fly ash typically involve FOB or CIF terms from the port of Hyderabad, with shipment volumes measured in tonnes. Lead times commonly range from four to six weeks, but exact timing should be confirmed with Sepra Exim. Payment terms are negotiated per transaction and may include letters of credit or advance payment, depending on the buyer’s risk profile.
Arrange a third‑party inspection at the loading port to verify bulk density, moisture content and absence of foreign material. Ensure the supplier provides a detailed packing list and shipping documents, including a bill of lading and customs clearance paperwork. Proper storage after arrival - dry, covered facilities - helps maintain the ash’s performance characteristics.
