For Cement and Concrete, Fly Ash must be selected by performance requirements, not only by product name.
Miningsun supplies export-ready Class F and Class C coal fly ash from China for international buyers who need stable quality, clear documentation and responsive quotation support. This guide explains what procurement teams usually ask before placing a trial order or full-container order.
Why specification matters
Fly ash is used as a supplementary cementitious material to improve workability, control heat and support long-term durability. The correct Fly Ash grade can improve performance, reduce processing risk and make procurement more predictable. The wrong grade can create handling, strength, viscosity, insulation or compatibility problems depending on the end use.
Buyers should connect the application requirement to a measurable specification such as chemistry, fineness, activity index, viscosity, bulk density or particle-size distribution.
What to request from the supplier
Ask for technical data before placing a purchase order. The supplier should be able to provide COA, LOI report, fineness report and third-party inspection when requested and explain which grade is normally used for Cement and Concrete.
- Relevant standard: ASTM C618 and EN 450-1
- Available grades: Class F, Class C and low-LOI grades
- Packaging options: 25 kg bags, 1 MT jumbo bags or bulk container supply
- Shipment from: Tianjin, Qingdao, Shanghai or major Chinese river ports
- COA and sample approval before bulk shipment
Procurement checklist
Before buying, confirm the grade, documents, packaging, loading port, target delivery date and inspection requirements. For high-value or high-risk projects, request a pre-shipment inspection and keep a sealed reference sample from the approved batch.
