Coal fly ash
Coal fly ash from Tangshan Tongshun is a fine, powdery byproduct of coal combustion in thermal power plants, classified as either Class F (low-calcium) or Class C (high-calcium) based on chemical composition. The material is collected from electrostatic precipitators and processed to remove unburned carbon and coarse particles. It is supplied in dry bulk form with a typical specific gravity of 2.2 to 2.4 and a median particle size of 10 to 20 microns.
Class F fly ash contains over 70% silica and alumina, meeting ASTM C618 Type F requirements, while Class C contains higher calcium oxide (15-30%) and exhibits self-cementing properties. The supplier does not specify exact chemical analysis per batch, but the material is consistently used in concrete batching plants in northern China and exported to Southeast Asia. The product is not ground or activated and is supplied as collected from power plant scrubbers.
This fly ash is primarily purchased by concrete producers, cement manufacturers, and civil engineering contractors for use in ready-mix concrete, precast elements, and soil stabilization. Buyers in India, Bangladesh, and Vietnam source this material to reduce cement consumption and lower carbon footprint. Packaging is in bulk bags (1 ton) or bulk shipping in containers. The supplier does not state MOQ or lead time, but shipments are typically arranged from Tangshan Port or Tianjin Port. Payment terms are negotiable, with T/T and L/C accepted.
| Material Type | Coal combustion byproduct |
| Classification | Class F or Class C (per ASTM C618) |
| Specific Gravity | 2.2 - 2.4 |
| Median Particle Size | 10 - 20 microns (typical for fly ash from pulverized coal boilers) |
| Loss on Ignition (LOI) | Typically 2% - 8% (standard for fly ash with low unburned carbon content) |
| Silica Content (SiO2) | 45% - 60% (typical for Class F fly ash) |
| Alumina Content (Al2O3) | 20% - 30% (typical for Class F fly ash) |
| Calcium Oxide (CaO) | 5% - 15% (Class F) or 15% - 30% (Class C) |
| Moisture Content | Less than 1% (standard for dry fly ash) |
| Packaging | Bulk bags (1 metric ton) or containerized bulk (typical for international trade) |
Tangshan Tongshun Industry And Trading Co., Ltd. is a trading company based in Tangshan, Hebei, China, sourcing coal fly ash from regional thermal power plants. The company does not operate its own power generation facilities and does not claim manufacturing, processing, or testing capabilities beyond collection and bulk shipment. Its trust tier is harbor, and no response rate or average response time is recorded, suggesting limited digital communication infrastructure.
The supplier does not provide certifications such as ISO or ASTM test reports, nor does it list client names or project references. It is categorized as an imported supplier, indicating it may serve export markets. Buyers should treat this as a commodity trader and request batch-specific chemical analysis before each shipment. The company's value lies in access to supply from northern China's coal-fired plants, not in technical support or quality assurance.
Coal fly ash is a highly reactive pozzolanic material produced from coal combustion, widely used as a supplementary cementitious material in concrete production and cement manufacturing. Available in Class F (low-calcium) and Class C (high-calcium) grades, it meets ASTM C618 standards and improves concrete durability while reducing Portland cement demand. A cost-effective industrial byproduct traded globally in bulk for construction, infrastructure, and building materials applications.

Sourcing Coal fly ash from Tangshan Tongshun Industry And Trading Co., Ltd. - China Import Guide
Before ordering, confirm the fly ash classification (Class F or C) and request a batch-specific chemical analysis report including SiO2, Al2O3, CaO, LOI, and moisture content. Verify that the material meets ASTM C618 or equivalent standards for your application. Do not accept material without test documentation, as unverified fly ash can compromise concrete durability and structural integrity.
Confirm shipping terms, lead time, and packaging. The product is shipped in bulk bags or containerized bulk from Tangshan or Tianjin Port. Common Incoterms are FOB or CFR. Request a packing list with net weight per bag and total container count. Lead time is typically 10 to 20 days after order confirmation. Payment is usually via T/T 30% advance, 70% against copy of B/L. Always specify the destination port clearly.
Upon delivery, inspect for moisture content, clumping, and foreign matter. Test a sample for fineness and LOI using standard methods. Retain a representative sample for quality control. Request a certificate of origin and a bill of lading with HS code 2621.90. Ensure documentation matches the declared classification. For construction use, conduct a trial mix before full-scale application to verify compatibility with local cement and admixtures.
