Import Basalt Powder — Buy in wholesale FOB from Supplier in Turkey

Astas Insaat offers basalt powder, a fine volcanic rock material processed from crushed basalt aggregate quarried in Turkey. The powder derives from natural basalt, a mafic silicate volcanic igneous rock, and is supplied in bulk or jumbo bags for industrial and infrastructure markets. The material's high compressive strength and durability make it suitable for demanding applications where mineral filler performance matters. The supplier indicates availability of analysis reports upon request, which buyers should obtain to confirm chemical and physical properties for their intended use.

Mineralogically, basalt powder consists of plagioclase feldspar, pyroxene, and olivine crystals ground to fine particle sizes, typically passing 75 micrometres or finer depending on application requirements. Standard basalt powder for asphalt filler applications typically exhibits a density of 2.8-3.0 g/cm³, with Mohs hardness around 6, and low water absorption compared to limestone alternatives. The mafic composition provides natural alkalinity and contributes to pozzolanic reactivity in certain cementitious systems. Typical loss on ignition values range from 1-3%, reflecting minimal organic content and carbonate contamination in properly processed material from volcanic sources.

Primary buyers include asphalt producers seeking filler for hot mix formulations, concrete admixture manufacturers, railway contractors specifying ballast fines, and agricultural operators applying basalt for soil remineralisation. The construction sector in Europe and the Middle East represents the largest import demand for Turkish basalt derivatives. Trade terms, minimum order quantities, and lead times must be confirmed directly with Astas Insaat, as these are not stated in the available data. Buyers should request sieve analysis, chemical composition, and plasticity index test results before finalising specifications.

Astas Insaat is based in Ardesen, Rize Province, in Turkey's northeastern Black Sea region, an area with extensive volcanic geology suitable for basalt quarrying. The supplier holds a harbor trust tier on the platform, with a response rate currently showing 0.00% and no recorded average response hours, indicating limited or no recent engagement through platform messaging. The company's address is confirmed as Rize 53400, Ardesen, Turkey, with operations focused on basalt rock powder, aggregate, and sand production for wholesale markets.

The supplier's communication indicates willingness to provide price quotations and analysis reports upon buyer enquiry, suggesting direct negotiation is the established trading pattern. No verified certifications, production capacity figures, export licence details, or years in operation are stated in the available profile. Buyers should independently verify quarry operational status, environmental compliance documentation, and export authorisation before committing to volume orders. The Rize location offers potential shipping access through Black Sea ports, though specific loading facilities and incoterms must be confirmed with Astas Insaat directly.
