Project New ternary cement

Characterisation of ternary cement « CEM X » with a high limestone filler content

Generalities  

Final aim of this research: Characterisation of a new European cement

Interest: Normative – General knowledge of hydraulic binders chemistry

Summary  

The European working group « Ad Hoc CEM X » of CEN/TC 51 WG 6 has given the mission to the CRIC-OCCN to characterize a new ternary cement « CEM X » with high limestone filler contents. This project is realised in collaboration with the CRIC-OCCN Testing Department.

The four compositions (AA, BB, CC and DD) of the CEM X which are manufactured industrially and tested are summarized in the table below:

The performances of these four compositions are compared between them and also with these of the following cements: CEM I, CEM II/B-M (S-L), CEM II/B-L and CEM III/B depending on the type of the test considered.

Three different test programs will be carried out:

− Full mechanical and chemical characterisation of the cements .

− Comparative study of the following performances::

+ Mechanical on concrete (density, compression, traction, Young-modulus, shrinkage, creep …) ;

+ Durability (Carbonation, Freeze-Thaw using two methods, Chloride diffusion in concrete and Sulphate Resistance on mortar).
