Belite clinkers with increasing aluminium content: effect of calcium aluminates on calcium silicate hydration
(Elsevier, 2022)Belite cements (BCs) could have advantages over Portland cements concerning durability, low heat development and the use of less demanding raw materials. The activation of BCs by sulfur addition at the clinkering stage and ... -
C-S-H seeding activation of Portland and Belite cements: An enlightening in situ synchrotron powder diffraction study
(Elsevier, 2022-11)C-S-H seeding in Portland cements is well known from basic scientific works and field applications. Moreover, this activation approach could be beneficial for low-CO2 cements under development where a general drawback is ... -
In situ synchrotron powder diffraction study of LC3 cement activation at very early ages by C-S-H nucleation seeding.
(Elsevier, 2024-02-22)Limestone Calcined Clay Cements, LC3, are being widely researched as low-carbon binders. However, the hydration reactions during the first day are key for their performances and they were not well known. Here, we employ ... -
Influence of curing temperature on belite cement hydration: a comparative study with Portland cement
(Elsevier, 2021-05-24)Belite cements (BCs) could be a more sustainable binder than Portland cements (PCs) but adequate knowledge of the hydration features has still to be built. In particular, the mild curing hydration temperature effects have ... -
Synchrotron Radiation Pair Distribution Function Analysis of Gels in Cements
(MDPI, 2017)The analysis of atomic ordering in a nanocrystalline phase with small particle sizes, below 5 nm, is intrinsically complicated because of the lack of long-range order. Furthermore, the presence of additional crystalline ...
