Fly ash

Fly ash offered by Cong Ty TNHH XNK & XD Phu Trang is a by‑product of coal combustion used as a pozzolanic additive in concrete. The material consists mainly of silica, alumina and iron oxides, providing high reactivity. Particle morphology is fine and spherical, which improves concrete flowability. The product complies with ASTM C618 Class F specifications.

In the construction industry, Class F fly ash is valued for its ability to enhance long‑term strength and reduce permeability of concrete structures. Typical industry fineness ranges from 3000 to 5000 cm² g⁻¹ (Blaine) and loss on ignition is usually between 5 % and 10 %. Moisture content is generally kept below 1 % to avoid adverse effects on mix design. Standard bulk density lies around 0.8 - 1.0 t m⁻³, allowing easy handling and storage.

Engineers and contractors use this ash in commercial buildings, bridges, highways and precast components to lower cement consumption and carbon emissions. The supplier ships in 1‑ton bulk bags and can arrange FOB or CIF terms from the port of Hai Phong. Buyers should confirm the exact chemical analysis report, packaging details and payment conditions directly with the supplier before placing an order.
