Cement and clinker inspection services

Cement is a hydraulic binder made by finely grinding clinker, natural gypsum and additives. Contact with water triggers hydration reactions and forms cement paste. As hydration products develop, the paste sets and subsequently hardens into a material with strength and dimensional stability.

Cement contributes directly to the quality of construction works. Its quality is therefore an important consideration when selecting construction materials.

ITVC Global offers the following cement inspection services to help customers control product quality.

Scope of work

At the plant

Pre-loading inspection: sample and analyze cement or clinker quality, and determine the weight of cargo loaded onto barges

Alongside the vessel

Determine the weight of cargo carried on barges alongside the vessel
Tally jumbo bags used for cement shipments
Take samples for moisture analysis
Determine the weight loaded onto the vessel by draught survey

Cement quality testing parameters

The tables retain the method codes, editions, sample quantities and timing from the original catalogue. Confirm the applicable method edition, sample quantity and turnaround time with the testing provider when ordering. The original catalogue does not specify the sample quantity for exactly two parameters; this requires separate confirmation.
