Dynamic Infracon Pvt Ltd supplies Class F coal fly ash sourced from major East Indian thermal power plants such as NTPC Kahalgaon, Tata Power and DVC stations. The material is classified as Class F under ASTM C618, with combined SiO₂, Al₂O₃ and Fe₂O₃ content exceeding 70 % by mass. It is described as having low carbon content, which helps maintain concrete purity, and it meets ISO and BIS certification requirements as noted in the supplier’s documentation. The ash is available for bulk shipment or in 20‑25 kg bags, depending on the buyer’s logistics preferences.
In the construction sector, Class F fly ash is used as a supplementary cementitious material, typically replacing 15‑30 % of Portland cement in concrete mixes. Its pozzolanic reaction improves long‑term strength, reduces heat of hydration and enhances durability against sulphate attack. Typical bulk density for this ash is between 0.80 and 0.90 g/cm³, and particle size is usually limited to under 75 µm to ensure consistent performance. The material also finds application in road base stabilization, brick making and as a filler in various building products.
Buyers should discuss trade terms such as FOB or CIF, confirm the desired packaging format and agree on any required documentation, including a certificate of analysis. Because the supplier’s response rate is currently listed as zero, it is prudent to request a sample batch and verify composition before committing to larger volumes. All regulatory compliance and certification copies should be obtained directly from Dynamic Infracon prior to shipment.

Coal Fly Ash is a pozzolanic byproduct sourced from major East Indian thermal power plants including NTPC Kahalgaon, Tata Power, and DVC stations. Classified as Class F per ASTM C618, it contains high silica and alumina content with low calcium oxide, making it ideal for cement and concrete blending, reducing construction costs while improving durability and workability. Exported in bulk or bagged form to Bangladesh ports, it serves as a cost-effective supplementary cementitious material for the South Asian construction and infrastructure sector.

Prior to ordering, verify the ash’s classification, chemical composition and the availability of a recent certificate of analysis. Request a sample to test fineness, bulk density and pozzolanic activity, especially if the material will be used in high‑strength concrete mixes. Confirm that the supplier can provide the required ISO and BIS certification documents and that the product meets any local environmental regulations.
Logistics are typically arranged on an FOB basis from the Kolkata port, though CIF terms can be negotiated. Lead times depend on the order size and packaging choice; the supplier should supply an estimated shipping schedule once the order details are finalised. Payment terms are usually a 30 % deposit with the balance payable before shipment, but they can be adapted after mutual agreement.
Upon receipt, arrange a third‑party inspection to confirm particle size distribution, moisture content and loss on ignition against the supplied test report. Verify the bulk density and ensure the packaging integrity, especially for bulk shipments. Retain all certificates of analysis and compliance documentation for quality control and future project audits.
