Reference Cement for Strength Measurement

This reference cement allows you to validate your process of applying the CEN 196-1 standard by comparing your expected results with results obtained by European reference laboratories for: Strength at 1,2,7 and 28days, Setting time, Heat of hydration.

The certificate of analysis was carried out and checked by the office of France-Ciments in Clichy 2 available references: RESI22 and soon the new RESI 25 at the end of 2025

DELIVERY

The Reference Cement is packaged in 2 aluminium sealed folios of 500g (2x500g), allowing to produce xxx samples

PARTICIPATION AND EXECUTION OF THE TESTS

An Inter laboratory testing campaign is organized each year by France-Ciments formerly ATILH. Participating in this campaign are the laboratories of the cement industry in France, Europe and more widely in the world, the laboratories of cement users and research and control centers in the field of construction materials.

This participation is mandatory for laboratories accredited by Cofrac for tests on cement. The tests are carried out according to standard methods where they exist and according to current and traditional methods where they do not.

STATIC ANALYSIS

Outlier removal is performed at the 98% level by the student test. Reiteration is set at this threshold, to keep only the values related to the “Normal or Gaussian” distribution and fully defined by the two parameters: mean and standard deviation. The coefficient of variation symbolized by ‘V’ is the ratio between the standard deviation and the mean ‘X’
