Accuracy in Cement Hydration Investigations: Combined X-ray Microtomography and Powder Diffraction Analyses
(MDPI, 2021-11-17)Cement hydration is a very complex set of processes. The evolution of the crystalline phases during hydration can be accurately followed by X-ray powder diffraction data evaluated by the Rietveld method. However, accurate ... -
Limestone calcined clay binders based on a Belite-rich cement
(Elsevier, 2023)Portland-based Limestone Calcined Clay Cements, LC3, are receiving considerable attention because the CO2 footprint can be reduced up to 40 %. Here, we report a related family: Belite-rich-LC3. These blends are expected ... -
Phase and microstructure evolutions in LC3 binders by multi-technique approach including synchrotron microtomography
(Elsevier, 2021-06-19)Limestone Calcined Clay Cements, LC3, are attracting a lot of attention as it is possible to reduce the clinker factor by 50%, which means a cement CO2 footprint reduction of 40%. This is compatible with maintaining the ... -
Reactivity of C3S and model cement in presence of Na2S2O3 and NaSCN
(Springer, 2023-01)The impact of NaSCN and Na2S2O3 on the reactivity, microstructure and morphology of C3S and model cement (with a clinker containing 85% C3S and 15% C3A) pastes was systematically investigated. Results concluded that both ... -
Recent Advances in C-S-H Nucleation Seeding for Improving Cement Performances
(IOAP-MDPI, 2023-02-09)Reducing cement CO2 footprint is a societal need. This is being achieved mainly by replacing an increasing amount of Portland clinker by supplementary cementitious materials. However, this comes at a price: lower mechanical ... -

Structure of stratlingite and effect of hydration methodology on microstructure
(ICE publishing, 2015)Stratlingite, Ca4Al2(OH)12[AlSi(OH)8]2•2H2O, is an AFm phase which appears as hydration product of aluminum-rich cements. These binders may be calcium aluminate cements, calcium sulfoaluminate cements and also Belite Calcium ...
