Fly ash from SMT Biomass is derived from rice husk combustion, with a confirmed amorphous silica (SiO2) content of 85% to 95%. This material is collected directly from biomass power operations in Thailand’s agricultural belt and processed to remove unburned carbon and coarse residues. It meets the physical and chemical criteria for use as a supplementary cementitious material in concrete, as defined by ASTM C618 and EN 450-1.
The product is classified as Class F pozzolan by its high silica content and low calcium oxide levels. Typical particle size distribution ranges from 1 to 100 microns, with a specific gravity of approximately 2.2. It contains less than 5% unburned carbon and under 1% moisture by weight, consistent with industry standards for pozzolanic additives. Unlike coal fly ash, this rice husk variant offers higher reactivity due to its fine, porous amorphous structure.
Buyers include ready-mix concrete producers, precast manufacturers, and cement blending facilities across Southeast Asia, the Middle East, and Europe. The material is supplied in bulk or 25kg polypropylene bags, with standard packaging designed for dry storage and dust control. Lead times are typically 10 to 15 days from order confirmation, and incoterms are negotiable based on destination port. MOQ is 1 metric ton, with container loads available upon request.

SMT Biomass operates from a processing facility in Bangkok, Thailand, sourcing rice husk ash directly from partner biomass plants in the central and northeastern rice-growing regions. The company is verified as a harbor-tier supplier with documented material traceability from combustion source to final product. Its operations focus exclusively on agricultural residue valorization, with no claim to coal fly ash or industrial by-product handling.
The listing does not state company size, years in operation, or client names. Response rate and average response time are not recorded, indicating limited direct buyer engagement on the platform. However, the consistency of material specifications and origin clarity suggest a stable, production-driven operation rather than a trading intermediary.
Rice Husk Ash Fly Ash is a high-quality pozzolanic material rich in amorphous silica, widely used as a supplementary cementitious material in concrete and cement production. It enhances durability, improves compressive strength, and reduces permeability in construction applications. This eco-friendly agricultural waste product is sourced primarily from rice-growing regions and is in strong demand globally as a sustainable alternative to traditional cement additives.

Before ordering, verify the material’s chemical composition through a recent lab report showing amorphous silica content, loss on ignition, and heavy metal levels. Confirm that the batch matches the 85-95% SiO2 range and that moisture content is below 1%. Request traceability documentation linking the ash to a verified rice husk combustion source in Thailand to ensure consistency.
Confirm the incoterm (typically FOB Bangkok or CIF destination), lead time (usually 10-15 days), and minimum order quantity (1 metric ton). Ensure packaging is sealed and labeled with batch number, date of production, and material classification. Bulk shipments require compatible unloading infrastructure. Payment terms are typically 30% advance, 70% against B/L copy.
Upon delivery, inspect for clumping, discoloration, or foreign matter. Conduct a simple sieve test to verify particle size distribution and a moisture test using oven drying. Request a certificate of analysis with XRD or XRF data. Retain a sample for third-party testing if used in structural applications. Documentation must include batch ID, origin, and compliance with ASTM C618 or EN 450-1.
