Clinker
Clinker from Contec is a cement intermediate produced by burning limestone and auxiliary raw materials at temperatures above 1400°C, yielding a granular product rich in calcium silicates, aluminates and ferrites. The material comprises key hydraulic phases such as tricalcium silicate (C3S) and dicalcium silicate (C2S), which impart the binding properties essential for concrete and construction applications. This clinker is supplied in bulk for cement grinding operations, meeting the core input requirements of cement producers globally.
The composition is typical for Portland cement clinker, with calcium silicates forming the majority of the mineral phases, alongside smaller proportions of calcium aluminate and calcium ferrite. These phases are standard in clinker used for ordinary Portland cement (OPC), providing the hydraulic reactivity required for strength development in concrete. The material is traded as a dry, granular commodity, with particle sizes typically ranging from 3 mm to 25 mm, suitable for direct use in cement mills.
This product is primarily sourced by cement manufacturers and construction material suppliers for grinding into finished cement. Buyers typically confirm bulk density, free lime content and liter weight to ensure consistency with their production specifications. Clinker is commonly shipped in bulk vessels, with trade terms and lead times negotiated based on port availability and production schedules.

Sourcing Clinker from Contec - Viet Nam Import Guide
Before placing an order, verify the chemical composition of Contec’s clinker, particularly the proportions of calcium silicates, aluminates and ferrites, as these directly impact cement quality. Request a mill test certificate (MTC) to confirm compliance with standards such as ASTM C150 or EN 197-1. Additionally, check for free lime content and liter weight to ensure the material meets your production requirements.
Confirm logistics details, including the Incoterms (e.g., FOB or CFR), port of loading in Viet Nam, and vessel availability. Lead times can vary based on production schedules and shipping arrangements, so agree on these in advance. Payment terms should also be clarified, with common options including letters of credit (LC) or bank transfers, depending on the buyer’s preference.
Conduct quality checks upon arrival, including visual inspection for particle size consistency and laboratory tests for chemical composition and hydraulic reactivity. Ensure all documentation, such as the bill of lading, packing list and MTC, is complete and accurate. For bulk shipments, coordinate with a third-party inspection agency to verify quantity and quality before discharge at the destination port.
