Bottom Ash from SMT Biomass is a rice husk ash pozzolanic material, a non-metallic mineral residue with high amorphous silica content produced from controlled combustion of rice husk in biomass power generation. The material is graded by particle size distribution and silica purity, sourced from major Thai rice-processing regions. It is traded internationally as a supplementary cementitious material, offering reduced permeability and improved long-term strength in concrete formulations compared to pure Portland cement blends.
The ash consists primarily of silicon dioxide in amorphous form, with smaller fractions of aluminium oxide, iron oxide, and residual carbon. Particle fineness varies with combustion temperature and milling practice; typical d50 values range from 10 to 45 micrometres depending on grade. Colour ranges from grey to black based on unburnt carbon content. The material is hygroscopic and requires dry storage to prevent premature hydration. Standard forms include raw unprocessed ash, classified fines, and milled products meeting specific Blaine fineness targets.
Primary applications include partial cement replacement in ready-mix concrete, precast elements, and mortar; production of blended cements under EN 197-1 or ASTM C595; road base stabilisation; and geotechnical fill where pozzolanic hardening is beneficial. Buyers include cement manufacturers, ready-mix operators, construction chemicals firms, and infrastructure contractors seeking cost reduction and carbon footprint improvement. Trade terms are typically FOB Bangkok or CFR main port, with bulk shipment in pneumatic tankemen or FIBC containers. Buyers should confirm current availability, exact silica content, and whether classification or milling is included.

The supplier operates from a Bangkok address in a major rice-processing and logistics corridor, with access to port infrastructure for bulk export. The listing carries a harbor trust tier, the baseline verification level on this marketplace, with no response rate or average response time data available. Buyers should initiate direct contact to assess communication reliability and technical competency.
Rice Husk Ash Bottom Ash is a non-metallic mineral residue from combustion of rice husk, high in amorphous silica content, serving as an economical pozzolanic material for cement, concrete, and construction applications. This ash is graded by particle size and silica purity, sourced from major rice-processing regions. Widely traded internationally as a cost-effective supplement to Portland cement and fly ash, it is exported in bulk or FIBC bags with MOQ typically starting at 20 MT.

Before placing an order with SMT Biomass, verify the exact amorphous silica content and reactivity through an independent laboratory test of a representative sample. Confirm the particle size distribution matches your mill or concrete mix design requirements, as Bangkok-sourced rice husk ash can vary with seasonal rice milling patterns. Request the most recent certificate of analysis and cross-check against your internal specification for LOI, moisture, and sulphate content. Ask whether SMT Biomass operates its own combustion facility or brokers ash from multiple biomass plants, as consistency in source affects long-term supply stability.
For logistics, confirm the loading port, typically Khlong Toei or Laem Chabang, and whether SMT Biomass arranges inland transport from Jomthong to port or requires buyer collection. CFR or CIF terms are common for regional buyers in Southeast Asia, while FOB suits those with established freight forwarders. Payment terms in Thai biomass ash trade typically range from advance payment for initial orders to documentary credit or open account for established relationships. Clarify whether the quoted price includes bulk loading into hold or container stuffing, and who bears demurrage if vessel loading is delayed.
Upon arrival, conduct independent inspection for moisture, colour uniformity, and lump formation. Sample each delivery for particle size analysis and LOI verification against the CoA. Retain sealed reference samples for dispute resolution. For cement plant use, run a trial batch in your laboratory mill to confirm grindability and strength contribution before committing to bulk volumes. Ensure all customs documentation, including certificate of origin, phytosanitary certificate where required, and MSDS, is complete to avoid port detention.
