Buy & Import Ultra Fine Fly Ash from Yescon - Wholesale Supply

The product offered by Yescon in Pakistan is Class F Ultra Fine Fly Ash, a coal‑combustion by‑product used as a supplementary cementitious material. It achieves a fineness of 400 mesh, with 80 % of particles passing a 45 µm sieve. The loss on ignition ranges from 3.5 % to 4.0 %, the moisture content is below 1.0 % and the sulphur trioxide (SO₃) content is limited to under 2.5 %. All parameters comply with the ASTM C618 specification for Class F pozzolan.

In the cement industry, Class F fly ash typically exhibits low calcium content and high silica‑alumina ratios, which contribute to long‑term strength gain. A fineness of 400 mesh is considered ultra‑fine and improves particle packing, reducing the water demand of concrete mixes. The low loss on ignition and moisture values reported by Yescon are within the usual industry limits that ensure stable storage and predictable reactivity. Such material is especially valuable for high‑strength concrete, grout and shotcrete where durability and permeability are critical.

Ready‑mix producers, precast manufacturers and infrastructure contractors commonly source this ash to replace a portion of Portland cement and lower overall carbon footprint. Yescon lists the product in bulk, but the minimum order quantity, exact packaging format and delivery incoterms must be confirmed directly with the supplier. Importers should request a recent Certificate of Analysis and verify that the ash meets the ASTM C618 test results before shipment.

Yescon is based in Karachi, Pakistan, with the address listed as Mubashar Plaza, University Road. The supplier carries a harbour‑tier verification on the marketplace, indicating basic vetting, while its response rate is currently recorded as 0 % and no average response time is provided, so buyers should anticipate confirming availability via direct contact.

Frequently Asked Questions About Ultra Fine Fly Ash from Yescon
The ash is graded to 400 mesh, meaning 80 % of the particles pass a 45 µm sieve. This fineness is verified by sieve analysis and is essential for achieving dense particle packing in high‑strength concrete.

Sourcing Ultra Fine Fly Ash from Yescon - Pakistan Import Guide

Before confirming a purchase, importers should obtain a recent Certificate of Analysis that details the ash’s chemical composition, LOI, fineness and sulphur content. Request a sample for laboratory testing against ASTM C618 to verify that the supplier’s data match the actual material. It is also prudent to ask for a safety data sheet covering handling and storage requirements, especially the need for dry conditions.

Yescon ships from the Karachi port network, and buyers can select common incoterms such as FOB Karachi or CIF Shanghai depending on their freight strategy. Because the supplier’s response rate is currently low, confirm the expected production lead‑time and shipping schedule in writing before the order is locked. Payment modalities, including letter of credit or advance transfer, should be agreed upon and linked to the receipt of the quality certificates.

Arrange for a third‑party inspection agency to sample the ash on board and test the fineness, LOI and sulphur levels according to ASTM C618 methods. The inspection report should be provided before cargo release, and any deviation from the agreed specifications must be documented for possible rejection. Maintaining records of the test results, shipping documents and the supplier’s certification will streamline customs clearance and future re‑orders.
