Grey Portland Clinker from Musa Yapi Ltd. is a calcium oxide-rich hydraulic binder intermediate, supplied in bulk or big bags FOB Turkey. It is produced to meet EN 197-1 and ASTM C150 standards, containing key mineral phases such as C3S and C2S, which are critical for the performance of the final cement. The clinker is sourced from Turkey’s Mediterranean, Aegean, Marmara, or Black Sea ports, offering flexibility for global buyers.
The mineral phases in this clinker, particularly C3S (alite) and C2S (belite), determine the setting characteristics and strength development of the cement. C3S hydrates rapidly, contributing to early strength, while C2S hydrates more slowly, providing long-term durability. Typical industry specifications for grey Portland clinker include a Blaine fineness of 300-400 m²/kg for the final cement and a 28-day compressive strength of 40-50 MPa, though these depend on the grinding process and additional additives.
This clinker is primarily used by cement producers and ready-mix concrete manufacturers seeking a reliable feedstock. Turkey’s strategic location as a Mediterranean export hub allows for efficient shipping to Europe, Africa, and the Middle East. Buyers should confirm the clinker’s compliance with their target cement standards and its suitability for specific applications, such as general-purpose, high-early-strength, or sulfate-resistant cement.

Before ordering grey Portland clinker from Musa Yapi Ltd., verify the chemical composition, particularly the lime saturation factor, silica modulus, and free lime content, as these are critical for cement performance. Request a mill test certificate to confirm compliance with EN 197-1 or ASTM C150 standards for the specific batch. Additionally, check for the presence of any minor phases or impurities that could affect the clinker’s hydraulic properties or the color of the final cement.
Confirm the logistics details, including the port of loading in Turkey and the Incoterms (typically FOB for this supplier). Ensure the chosen port can accommodate the vessel type and size required for your shipment. Lead times may vary depending on vessel availability, so coordinate with the supplier to align production and shipping schedules with your demand. For big bag shipments, verify the bag specifications and handling requirements to avoid damage during transit.
Upon arrival, conduct quality checks, including visual inspection for color consistency and laboratory tests for chemical and physical properties. For bulk shipments, consider third-party inspection services to verify the quantity and condition of the clinker before discharge. Ensure all documentation, such as the bill of lading, commercial invoice, and certificate of origin, is accurate and complete to avoid customs delays. For cement producers, also confirm the clinker’s grindability to optimize mill performance and energy consumption.
